-4.1.28 - Release 16 October 2007
-
-backout changes (B1) & (B2) as they've caused NAT entries to persist for
-too long and possibly other side effects.
-
-Still need to compile in our own radix.c for Solaris as the one in S10U4
-has a different alignment of structure members (causes panic)
-
-keep state doesn't work with multicast/broadcast packets (makes UPnP easier)
-
-ippool -l may only lists every 2nd pool's contents
-
-4.1.27 - Released 29 September 2007
-

+Installation instructions:
+=========================
+
+1. Update HP-UX Kernel
+----------------------
+General instructions on preparation for installing and proceeding with an
+installation of IPFilter on HP-UX can be found at:
+http://coombs.anu.edu.au/~avalon/ipf-mentat.html
+
+You are required to at least install the latest jumbo patches from HP,
+for HP-UX 11.  A summary of those that I used can be found at:
+At http://coombs.anu.edu.au/~avalon/ipf-hp11.html
+
+I do not recommend using anything less than as many of these as will apply
+to your own system.
+
+2. Build and Install pfil
+-------------------------
+Next, you need to download and install "pfil".  This is a STREAMS interface
+for packet filtering that removes the need for packet filtering code to be
+written as a STREAMS module.  This can be downloaded from
+
+http://coombs.anu.edu.au/~avalon/pfil-2.1.1.tar.gz
+
+Unpack this and type "make" in the pfil directory.  Once compelte, type
+"make install" to kick off the installation.
+
+3. Build and Install IP Filter
+------------------------------
+Having got this far, you now need to download the latest IP Filter package
+and compile/install that.  The source code for IP Filter can be obtained
+from:
+http://coombs.anu.edu.au/~avalon/ip-filter.html
+
+Download the latest version that is 4.1 or greater.
+
+This should be unpacked into the same directory as "pfil" is.  The
+directory layout will look like this:
+
+/directory/ip_fil4.*
+/directory/pfil
+
+This complete, do a "make hpux" in the ip_fil4.* directory, followed
+by a "make install".  You will need to reboot for it to become active.

-IP-Filter on Linux 2.0.31
--------------------------
 
-NOTE: I have *ONLY* compiled and created patches for using IP Filter on
-      Linux 2.0.31.  Any other kernel revision may need seprate patches.
-      Also, I've only tested on a x86 CPU so I can't make any guarantees
-      about it working on Sparc/Mac/Amiga.
+The Linux 2.4 and 2.6 series of kernels are supported by this software.
 
-First, you should do a sanity check of your system to make sure it will
-compile IP Filter.  You will need a "libfl" and a "libelf".  If you don't
-have these, install them before proceeding.
+Building has been tested on RedHat 9 and SUSE 9.x, although your results
+may vary.
 
-The installation and compiliation process assumes that Linux 2.0.31
-will be in the /usr/src/linux directory and that all the symbolic links
-in /usr/include match.  /usr/src/linux may be a symbolic link too, but
-it must point to a 2.0.31 kernel source tree.
+In general, you will need to have your kernel source in /usr/src/linux
+to build IPFilter but different Linux projects may differ.  See below.
 
-The first step is to make the IP Filter binaries.  Do this with a
-"make linux" from the ip_fil3.2.x directory.  If this completes with
-no errors, install IP Filter with a "make install-linux".
+Projects
+========
 
-Now that the user part of it is complete, it is time to work on the kernel.
-To start this off, run "Linux/minstall".  This will configure the devices
-you will need for the IP Filter.  Then run "Linux/kinstall".  This will
-patch your kernel source code and configuration files so you can enabled IP
-Filter.  You must now go to /usr/src/linux and configure your kernel using one
-of the available interfaces to enable IP Filter.  IP Filter will be presented
-as a three way choice "y/m/n" - select "m" to enable it.  Save your kernel
-configuration file, rebuild, install and reboot with the new kernel.
+Fedora
+------
+For Fedora, point your web browser at this URL and follow the instructions:
+http://fedoraproject.org/wiki/Building_a_custom_kernel
 
-When you've rebooted with the new kernel, you should be able to load
-IP Filter with the command "insmod if_ipl".  All going will, you will
-see a message like this on your console:
+For me, following the instructions put all of the kernel source code (for
+Fedora 11) in $HOME/rpmbuild. As an example of the directory I used, see
+BUILDROOT in Makefile.
 
-IP Filter: initialized.  Default = pass all, Logging = enabled
 
-indicating that IP Filter has successfully been loaded into the kernel
-and is awaiting.
+Building IPFilter
+=================
+The steps required are as follows:
 
-Darren
+1. Create the binaries
+
+make linux
+
+2. Create the RPM file
 
-Features Not Available on Linux, yet:
+make install-linux
 
-- compiled into the kernel
-"<action> in on <if> to <if> ..."
-"<action> in on <if> dup-to <if> ..."
-"<action> in on <if> fastroute ..."
-"block return-rst ..."
-"map ... proxy ..." (Linux's masquerading is better at present)
+3. In an ideal world, this step wouldn't be required.  At this point you
+need to locate the actual RPM file as the rpmbuild failed in the previous
+step.  Now run:
 
+rpm -i /path/to/ipfilter.rpm
+
+At this point IPFilter should be installed and ready to use.

+Installing IPFilter into OpenBSD 3.0 Kernel
+===========================================
+The installation of IPFilter should be as easy as following the steps
+below.  In cases where "i386" is mentioned, if you are working on a
+different platform, substitute that name there and it should work equally
+as well.  The patches include enabling IPFilter for IPv4 filtering, IPv6
+filtering and bridge filtering.
+
+The commands given below are intended as guides rather than exact matches
+on what needs to be typed.  In many cases, paths to files or directories
+may bear little resemblence to what is presented below.
+
+You may encounter difficulties with step 7 if you have made changes to the
+rc files which cause "patch" to not be able to work out how to apply the
+changes correctly.
+
+If the below steps are followed with no problems then it should be safe to
+perform step 8 and reboot with the new kernel.  Of course if you are not
+using GENERIC then substitute GENERIC for your kernel name.  If your kernel
+config file includes the "GENERIC" one then you will not need to add explicit
+options for IPFilter.
+
+1. Extract your source tree into /usr/src, creating /usr/src/sys.
+
+cd /usr/src
+gunzip -c sys.tar.gz | tar xpf -
+
+2. Unpack IPFilter and apply the patches to the kernel source

+=====================
+Patches to include making IPFilter devices can be found in the file
+3.3-MAKEDEV-diffs.  These diffs are generally only of interested if
+you are going to be building a distribution for others and want the
+correct MAKEDEV scripts to be built.  You may also wish to use this
+to patch /dev/MAKEDEV on your machine to be correct.  Pre-fab'd MAKEDEV
+scripts (or individual patches) for each architecture are not provided.
+You will need to have extracted "./etc" from src.tar.gz to use these

+
+Installing IPFilter into OpenBSD 3.4 Kernel
+===========================================
+The installation of IPFilter should be as easy as following the steps
+below.  In cases where "i386" is mentioned, if you are working on a
+different platform, substitute that name there and it should work equally
+as well.  The patches include enabling IPFilter for IPv4 filtering, IPv6
+filtering and bridge filtering.
+
+The commands given below are intended as guides rather than exact matches
+on what needs to be typed.  In many cases, paths to files or directories
+may bear little resemblence to what is presented below.
+
+You may encounter difficulties with step 7 if you have made changes to the
+rc files which cause "patch" to not be able to work out how to apply the
+changes correctly.
+
+If the below steps are followed with no problems then it should be safe to
+perform step 8 and reboot with the new kernel.  Of course if you are not
+using GENERIC then substitute GENERIC for your kernel name.  If your kernel
+config file includes the "GENERIC" one then you will not need to add explicit
+options for IPFilter.
+
+1. Extract your source tree into /usr/src, creating /usr/src/sys.
+
+cd /usr/src
+gunzip -c sys.tar.gz | tar xpf -
+
+2. Unpack IPFilter and apply the patches to the kernel source 
+
+cd ~
+gunzip -c ip_fil4next.tar.gz | tar xpf -
+cd /usr/src
+patch < ~/ip_fil4.1.14/OpenBSD-3/3.4-sys-diffs
+
+3. Add IPFilter to the source code tree:
+
+cd ~/ip_fil4next
+BSD/kupgrade
+
+If you want to build a new release with IPFilter, stop here and goto
+the section below titled "Building a Release".
+
+4. Build a new OpenBSD kernel
+
+/bin/rm -rf /sys/arch/i386/compile/GENERIC
+cd /sys/arch/i386/conf
+config GENERIC
+cd ../compile/GENERIC
+make depend && make

+
+5. Build and install IPFilter
+

-   
-1. DEFINITIONS
-
-   "Contribution" means:
-   
-    a. in the case of QSS: (i) the Original Program, where the Original
-       Program originates from QSS, (ii) changes and/or additions to
-       Unrestricted Open Source, where the Original Program originates
-       from Unrestricted Open Source and where such changes and/or
-       additions originate from QSS, and (iii) changes and/or additions
-       to the Program where such changes and/or additions originate from
-       QSS.
-    b. in the case of each Contributor, changes and/or additions to the
-       Program, where such changes and/or additions originate from and
-       are distributed by that particular Contributor.
-       
-   A Contribution 'originates' from a Contributor if it was added to the
-   Program by such Contributor itself or anyone acting on such
-   Contributor's behalf. Contributions do not include additions to the
-   Program which: (i) are separate modules of software distributed in
-   conjunction with the Program under their own license agreement, and
-   (ii) are not derivative works of the Program.
-   
-   "Contributor" means QSS and any other entity that distributes the
-   Program.
-   
-   "Licensed Patents " mean patent claims licensable by Contributor to
-   others, which are necessarily infringed by the use or sale of its
-   Contribution alone or when combined with the Program.
-   
-   "Unrestricted Open Source" means published source code that is
-   licensed for free use and distribution under an unrestricted licensing
-   and distribution model, such as the Berkley Software Design ("BSD")
-   and "BSD-like" licenses. It specifically excludes any source code
-   licensed under any version of the GNU General Public License (GPL) or
-   the GNU Lesser/Library GPL. All "Unrestricted Open Source" license
-   terms appear or are clearly identified in the header of any affected
-   source code for the Original Program.
-   
-   "Original Program" means the original version of the software
-   accompanying this Agreement as released by QSS, including source code,
-   object code and documentation, if any.
-   
-   "Program" means the Original Program and Contributions.
-   
-   "Recipient" means anyone who receives the Program under this
-   Agreement, including all Contributors.
-   
-2. GRANT OF RIGHTS
-
-    a. Subject to the terms of this Agreement, each Contributor hereby
-       grants Recipient a non-exclusive, worldwide, royalty-free
-       copyright license to reproduce, prepare derivative works of,
-       publicly display, publicly perform, and directly and indirectly
-       sublicense and distribute the Contribution of such Contributor, if
-       any, and such derivative works, in source code and object code
-       form.
-    b. Subject to the terms of this Agreement, each Contributor hereby
-       grants Recipient a non-exclusive, worldwide, royalty-free patent
-       license under Licensed Patents to make, use, sell, offer to sell,
-       import and otherwise transfer the Contribution of such
-       Contributor, if any, in source code and object code form. This
-       patent license shall apply to the combination of the Contribution
-       and the Program if, at the time the Contribution is added by the
-       Contributor, such addition of the Contribution causes such
-       combination to be covered by the Licensed Patents. The patent
-       license shall not apply to any other combinations which include
-       the Contribution.
-    c. Recipient understands that although each Contributor grants the
-       licenses to its Contributions set forth herein, no assurances are
-       provided by any Contributor that the Program does not infringe the
-       patent or other intellectual property rights of any other entity.
-       Each Contributor disclaims any liability to Recipient for claims
-       brought by any other entity based on infringement of intellectual
-       property rights or otherwise. As a condition to exercising the
-       rights and licenses granted hereunder, each Recipient hereby
-       assumes sole responsibility to secure any other intellectual
-       property rights needed, if any. For example, if a third party
-       patent license is required to allow Recipient to distribute the
-       Program, it is Recipient's responsibility to acquire that license
-       before distributing the Program.
-    d. Each Contributor represents that to its knowledge it has
-       sufficient copyright rights in its Contribution, if any, to grant
-       the copyright license set forth in this Agreement.
-       
-  3. REQUIREMENTS
-  
-   A Contributor may choose to distribute the Program in object code form
-   under its own license agreement, provided that:
-   
-    a. it complies with the terms and conditions of this Agreement; and
-    b. its license agreement:
-         i. effectively disclaims on behalf of all Contributors all
-            warranties and conditions, express and implied, including
-            warranties or conditions of title and non-infringement, and
-            implied warranties or conditions of merchantability and
-            fitness for a particular purpose;
-        ii. effectively excludes on behalf of all Contributors all
-            liability for damages, including direct, indirect, special,
-            incidental and consequential damages, such as lost profits;
-            and
-        iii. states that any provisions which differ from this Agreement
-            are offered by that Contributor alone and not by any other
-            party.
-       
-   If the Program is made available in source code form:
-   
-    a. it must be made available under this Agreement; and
-    b. a copy of this Agreement must be included with each copy of the
-       Program. Each Contributor must include the following in a
-       conspicuous location in the Program along with any other copyright
-       or attribution statements required by the terms of any applicable
-       Unrestricted Open Source license:
-       Copyright {date here}, QNX Software Systems Ltd. and others. All
-       Rights Reserved.
-       
-   In addition, each Contributor must identify itself as the originator
-   of its Contribution, if any, in a manner that reasonably allows
-   subsequent Recipients to identify the originator of the Contribution.
-   
-  4. COMMERCIAL DISTRIBUTION
-  
-   Commercial distributors of software may accept certain
-   responsibilities with respect to end users, business partners and the
-   like. While this license is intended to facilitate the commercial use
-   of the Program, the Contributor who includes the Program in a
-   commercial product offering should do so in a manner which does not
-   create potential liability for other Contributors. Therefore, if a
-   Contributor includes the Program in a commercial product offering,
-   such Contributor ("Commercial Contributor") hereby agrees to defend
-   and indemnify every other Contributor ("Indemnified Contributor")
-   against any losses, damages and costs (collectively "Losses") arising
-   from claims, lawsuits and other legal actions brought by a third party
-   against the Indemnified Contributor to the extent caused by the acts
-   or omissions of such Commercial Contributor in connection with its
-   distribution of the Program in a commercial product offering. The
-   obligations in this section do not apply to any claims or Losses
-   relating to any actual or alleged intellectual property infringement.
-   In order to qualify, an Indemnified Contributor must: a) promptly
-   notify the Commercial Contributor in writing of such claim, and b)
-   allow the Commercial Contributor to control, and cooperate with the
-   Commercial Contributor in, the defense and any related settlement
-   negotiations. The Indemnified Contributor may participate in any such
-   claim at its own expense.
-   
-   For example, a Contributor might include the Program in a commercial
-   product offering, Product X. That Contributor is then a Commercial
-   Contributor. If that Commercial Contributor then makes performance
-   claims, or offers warranties related to Product X, those performance
-   claims and warranties are such Commercial Contributor's responsibility
-   alone. Under this section, the Commercial Contributor would have to
-   defend claims against the other Contributors related to those
-   performance claims and warranties, and if a court requires any other
-   Contributor to pay any damages as a result, the Commercial Contributor
-   must pay those damages.
-   
-  5. NO WARRANTY
-  
-   Recipient acknowledges that there may be errors or bugs in the Program
-   and that it is imperative that Recipient conduct thorough testing to
-   identify and correct any problems prior to the productive use or
-   commercial release of any products that use the Program, and prior to
-   the release of any modifications, updates or enhancements thereto.
-   
-   EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS
-   PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY
-   KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY
-   WARRANTIES OR CONDITIONS OF TITLE, NON- INFRINGEMENT, MERCHANTABILITY
-   OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely
-   responsible for determining the appropriateness of using and
-   distributing the Program and assumes all risks associated with its
-   exercise of rights under this Agreement, including but not limited to
-   the risks and costs of program errors, compliance with applicable
-   laws, damage to or loss of data, programs or equipment, and
-   unavailability or interruption of operations.
-   
-  6. DISCLAIMER OF LIABILITY
-  
-   EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR
-   ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT,
-   INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING
-   WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF
-   LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING
-   NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR
-   DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED
-   HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
-   
-  7. GENERAL
-  
-   If any provision of this Agreement is invalid or unenforceable under
-   applicable law, it shall not affect the validity or enforceability of
-   the remainder of the terms of this Agreement, and without further
-   action by the parties hereto, such provision shall be reformed to the
-   minimum extent necessary to make such provision valid and enforceable.
-   
-   If Recipient institutes patent litigation against a Contributor with
-   respect to a patent applicable to software (including a cross-claim or
-   counterclaim in a lawsuit), then any patent licenses granted by that
-   Contributor to such recipient under this Agreement shall terminate as
-   of the date such litigation is filed. In addition, If Recipient
-   institutes patent litigation against any entity (including a
-   cross-claim or counterclaim in a lawsuit) alleging that the Program
-   itself (excluding combinations of the Program with other software or
-   hardware) infringes such Recipient's patent(s), then such Recipient's
-   rights granted under Section 2(b) shall terminate as of the date such
-   litigation is filed.
-   
-   All Recipient's rights under this Agreement shall terminate if it
-   fails to comply with any of the material terms or conditions of this
-   Agreement and does not cure such failure in a reasonable period of
-   time after becoming aware of such noncompliance. If all Recipient's
-   rights under this Agreement terminate, Recipient agrees to cease use
-   and distribution of the Program as soon as reasonably practicable.
-   However, Recipient's obligations under this Agreement and any licenses
-   granted by Recipient relating to the Program shall continue and
-   survive.
-   
-   QSS may publish new versions (including revisions) of this Agreement
-   from time to time. Each new version of the Agreement will be given a
-   distinguishing version number. The Program (including Contributions)
-   may always be distributed subject to the version of the Agreement
-   under which it was received. In addition, after a new version of the
-   Agreement is published, Contributor may elect to distribute the
-   Program (including its Contributions) under the new version. No one
-   other than QSS has the right to modify this Agreement. Except as
-   expressly stated in Sections 2(a) and 2(b) above, Recipient receives
-   no rights or licenses to the intellectual property of any Contributor
-   under this Agreement, whether expressly, by implication, estoppel or
-   otherwise. All rights in the Program not expressly granted under this
-   Agreement are reserved.
-   
-   This Agreement is governed by the laws in force in the Province of
-   Ontario, Canada without regard to the conflict of law provisions
-   therein. The parties expressly disclaim the provisions of the United
-   Nations Convention on Contracts for the International Sale of Goods.
-   No party to this Agreement will bring a legal action under this
-   Agreement more than one year after the cause of action arose. Each
-   party waives its rights to a jury trial in any resulting litigation.

-NOTE: To all those upgrading from versions prior to 3.2.11 who used NAT
-      AND setup ACL's to allow untranslated address through from outside,
-
-     THIS HAS BEEN FIXED
-
-     so your ACL's will now be `broken'.  Please correct your ACL's to
-     match the the untranslated addresses (the way it was meant to work).

+What's new in 5.1
+=================
+
+General
+-------
+* all of the tuneables can now be set at any time, not just whilst disabled
+  or prior to loading rules;
+
+* group identifiers may now be a number or name (universal);
+
+* man pages rewritten
+
+* tunables can now be set via ipf.conf;
+
+Logging
+-------
+* ipmon.conf can now be used to generate SNMPv1 and SNMPv2 traps using
+  information from log entries from the kernel;
+
+NAT changes
+-----------
+* DNS proxy for the kernel that can block queries based on domain names;        
+
+* FTP proxy can be configured to limit data connections to one or many
+  connections per client;
+
+* NAT on IPv6 is now supported;
+
+* rewrite command allows changing both the source and destination address
+  in a single NAT rule;
+
+* simple encapsulation can now be configured with ipnat.conf,
+
+* TFTP proxy now included;
+
+Packet Filtering
+----------------
+* acceptance of ICMP packets for "keep state" rules can be refined through
+  the use of filtering rules;
+
+* alternative form for writing rules using simple filtering expressions;
+
+* CIPSO headers now recognised and analysed for filtering on DOI;
+
+* comments can now be a part of a rule and loaded into the kernel and
+  thus displayed with ipfstat;
+
+* decapsulation rules allow filtering on inner headers, providing they
+  are not encrypted;
+
+* interface names, aside from that the packet is on, can be present in
+  filter rules;
+
+* internally now a single list of filter rules, there is no longer an
+  IPv4 and IPv6 list;
+
+* rules can now be added with an expiration time, allowing for their
+  automatic removal after some period of time;
+
+* single file, ipf.conf, can now be used for both IPv4 and IPv6 rules;
+
+* stateful filtering now allows for limits to be placed on the number
+  of distinct hosts allowed per rule;
+
+Pools
+-----
+* addresses added to a pool via the command line (only!) can be given
+  an expiration timeout;
+
+* destination lists are a new type of address pool, primarily for use with
+  NAT rdr rules, supporting newer algorithms for target selection;
+
+* raw whois information saved to a file can be used to populate a pool;
+
+Solaris
+-------
+* support for use in zones with exclusive IP instances fully supported.
+
+Tools
+-----
+* use of matching expressions allows for refining what is displayed or
+  flushed;

+ * 2: for to/dup-to rule, if an ip address is specified after

-.SH NAME
-ipf \- alters packet filtering lists for IP packet input and ouput
-.SH SYNOPSIS
-.B ipf
-[
-.B \-AdDEInorsUvyzZ
-] [
-.B \-l
-<block|pass|nomatch>
-] [
-.B \-F
-<i|o|a>

-<\fIfilename\fP>
-[...]]
-.SH DESCRIPTION
-.PP
-\fBipf\fP opens the filenames listed (treating "\-" as stdin) and parses the
-file for a set of rules which are to be added or removed from the packet
-filter rule set.
-.PP
-Each rule processed by \fBipf\fP
-is added to the kernel's internal lists if there are no parsing problems.
-Rules are added to the end of the internal lists, matching the order in
-which they appear when given to \fBipf\fP.
-.SH OPTIONS
-.TP
-.B \-A
-Set the list to make changes to the active list (default).
-.TP
-.B \-d
-Turn debug mode on.  Causes a hexdump of filter rules to be generated as
-it processes each one.
-.TP
-.B \-D
-Disable the filter (if enabled).  Not effective for loadable kernel versions.
-.TP
-.B \-E
-Enable the filter (if disabled).  Not effective for loadable kernel versions.
-.TP
-.BR \-F \0<param>
-This option specifies which filter list to flush.  The parameter should
-either be "i" (input), "o" (output) or "a" (remove all filter rules).
-Either a single letter or an entire word starting with the appropriate
-letter maybe used.  This option maybe before, or after, any other with
-the order on the command line being that used to execute options.
-.TP
-.BR \-f \0<filename>
-This option specifies which files
-\fBipf\fP should use to get input from for modifying the packet filter rule
-lists.
-.TP
-.B \-I
-Set the list to make changes to the inactive list.
-.TP
-.B \-l \0<param>
-Use of the \fB-l\fP flag toggles default logging of packets.  Valid
-arguments to this option are \fBpass\fP, \fBblock\fP and \fBnomatch\fP.
-When an option is set, any packet which exits filtering and matches the
-set category is logged.  This is most useful for causing all packets
-which don't match any of the loaded rules to be logged.
-.TP
-.B \-n
-This flag (no-change) prevents \fBipf\fP from actually making any ioctl
-calls or doing anything which would alter the currently running kernel.
-.TP
-.B \-o
-Force rules by default to be added/deleted to/from the output list, rather
-than the (default) input list.
-.TP
-.B \-r
-Remove matching filter rules rather than add them to the internal lists
-.TP
-.B \-s
-Swap the active filter list in use to be the "other" one.
-.TP
-.B \-U
-(SOLARIS 2 ONLY) Block packets travelling along the data stream which aren't
-recognised as IP packets.  They will be printed out on the console.
-.TP
-.B \-v
-Turn verbose mode on.  Displays information relating to rule processing.
-.TP
-.B \-y
-(SOLARIS 2 ONLY) Manually resync the in-kernel interface list maintained
-by IP Filter with the current interface status list.
-.TP
-.B \-z
-For each rule in the input file, reset the statistics for it to zero and
-display the statistics prior to them being zero'd.
-.TP
-.B \-Z
-Zero global statistics held in the kernel for filtering only (this doesn't
-affect fragment or state statistics).
-.DT
-.SH SEE ALSO
-ipfstat(1), ipftest(1), ipf(5), mkfilters(1)
-.SH DIAGNOSTICS
-.PP
-Needs to be run as root for the packet filtering lists to actually
-be affected inside the kernel.

 .SH NAME
-ipf, ipf.conf, ipf6.conf \- IP packet filter rule syntax
+ipf, ipf.conf \- IPFilter firewall rules file format
 .SH DESCRIPTION
 .PP
-A rule file for \fBipf\fP may have any name or even be stdin.  As
-\fBipfstat\fP produces parsable rules as output when displaying the internal
-kernel filter lists, it is quite plausible to use its output to feed back
-into \fBipf\fP.  Thus, to remove all filters on input packets, the following
-could be done:
+The ipf.conf file is used to specify rules for the firewall, packet
+authentication and packet accounting components of IPFilter. To load rules
+specified in the ipf.conf file, the ipf(8) program is used.
+.PP
+For use as a firewall, there are two important rule types: those that block
+and drop packets (block rules) and those that allow packets through (pass
+rules.) Accompanying the decision to apply is a collection of statements
+that specify under what conditions the result is to be applied and how.
+.PP
+The simplest rules that can be used in ipf.conf are expressed like this:
+.PP
 .nf
-
-\fC# ipfstat \-i | ipf \-rf \-\fP
+block in all
+pass out all
 .fi
-.SH GRAMMAR
 .PP
-The format used by \fBipf\fP for construction of filtering rules can be
-described using the following grammar in BNF:
-\fC
+Each rule must contain at least the following three components
+.RS
+.IP *
+a decision keyword (pass, block, etc.)
+.IP *
+the direction of the packet (in or out)
+.IP *
+address patterns or "all" to match any address information
+.RE
+.SS Long lines
+.PP
+For rules lines that are particularly long, it is possible to split
+them over multiple lines implicity like this:

-.fi
-.PP
-This syntax is somewhat simplified for readability, some combinations
-that match this grammar are disallowed by the software because they do
-not make sense (such as tcp \fBflags\fP for non-TCP packets).
-.SH FILTER RULES
-.PP
-The "briefest" valid rules are (currently) no-ops and are of the form:
-.nf
-       block in all
-       pass in all
-       log out all
-       count in all
-.fi
-.PP
-Filter rules are checked in order, with the last matching rule
-determining the fate of the packet (but see the \fBquick\fP option,
-below).
-.PP
-Filters are installed by default at the end of the kernel's filter
-lists, prepending the rule with \fB@n\fP will cause it to be inserted
-as the n'th entry in the current list. This is especially useful when
-modifying and testing active filter rulesets. See ipf(8) for more
-information.
-.SH ACTIONS
-.PP
-The action indicates what to do with the packet if it matches the rest
-of the filter rule. Each rule MUST have an action. The following
-actions are recognised:
-.TP
-.B block
-indicates that the packet should be flagged to be dropped. In response
-to blocking a packet, the filter may be instructed to send a reply
-packet, either an ICMP packet (\fBreturn-icmp\fP), an ICMP packet
-masquerading as being from the original packet's destination
-(\fBreturn-icmp-as-dest\fP), or a TCP "reset" (\fBreturn-rst\fP).  An
-ICMP packet may be generated in response to any IP packet, and its
-type may optionally be specified, but a TCP reset may only be used
-with a rule which is being applied to TCP packets.  When using
-\fBreturn-icmp\fP or \fBreturn-icmp-as-dest\fP, it is possible to specify
-the actual unreachable `type'.  That is, whether it is a network
-unreachable, port unreachable or even administratively
-prohibited. This is done by enclosing the ICMP code associated with
-it in parenthesis directly following \fBreturn-icmp\fP or
-\fBreturn-icmp-as-dest\fP as follows:
-.nf
-        block return-icmp(11) ...
-.fi
-.PP
-Would return a Type-Of-Service (TOS) ICMP unreachable error.
-.TP
-.B pass
-will flag the packet to be let through the filter.  
-.TP
-.B log
-causes the packet to be logged (as described in the LOGGING section
-below) and has no effect on whether the packet will be allowed through
-the filter.
-.TP
-.B count
-causes the packet to be included in the accounting statistics kept by
-the filter, and has no effect on whether the packet will be allowed through
-the filter. These statistics are viewable with ipfstat(8).
-.TP
-.B call
-this action is used to invoke the named function in the kernel, which
-must conform to a specific calling interface. Customised actions and
-semantics can thus be implemented to supplement those available. This
-feature is for use by knowledgeable hackers, and is not currently
-documented.
-.TP
-.B "skip <n>"
-causes the filter to skip over the next \fIn\fP filter rules.  If a rule is
-inserted or deleted inside the region being skipped over, then the value of
-\fIn\fP is adjusted appropriately.
-.TP
-.B auth
-this allows authentication to be performed by a user-space program running
-and waiting for packet information to validate.  The packet is held for a
-period of time in an internal buffer whilst it waits for the program to return
-to the kernel the \fIreal\fP flags for whether it should be allowed through
-or not.  Such a program might look at the source address and request some sort
-of authentication from the user (such as a password) before allowing the
-packet through or telling the kernel to drop it if from an unrecognised source.
-.TP
-.B preauth
-tells the filter that for packets of this class, it should look in the
-pre-authenticated list for further clarification.  If no further matching
-rule is found, the packet will be dropped (the FR_PREAUTH is not the same
-as FR_PASS).  If a further matching rule is found, the result from that is
-used in its instead.  This might be used in a situation where a person
-\fIlogs in\fP to the firewall and it sets up some temporary rules defining
-the access for that person.
-.PP
-The next word must be either \fBin\fP or \fBout\fP.  Each packet
-moving through the kernel is either inbound (just been received on an
-interface, and moving towards the kernel's protocol processing) or
-outbound (transmitted or forwarded by the stack, and on its way to an
-interface). There is a requirement that each filter rule explicitly
-state which side of the I/O it is to be used on.
-.SH OPTIONS
-.PP
-The list of options is brief, and all are indeed optional. Where
-options are used, they must be present in the order shown here. These
-are the currently supported options:
-.TP
-.B log
-indicates that, should this be the last matching rule, the packet
-header will be written to the \fBipl\fP log (as described in the
-LOGGING section below).
-.TP
-.B tag tagid
-indicates that, if this rule causes the packet to be logged or entered
-in the state table, the tagid will be logged as part of the log entry.
-This can be used to quickly match "similar" rules in scripts that post
-process the log files for e.g. generation of security reports or accounting
-purposes. The tagid is a 32 bit unsigned integer.
-.TP
-.B quick
-allows "short-cut" rules in order to speed up the filter or override
-later rules.  If a packet matches a filter rule which is marked as
-\fBquick\fP, this rule will be the last rule checked, allowing a
-"short-circuit" path to avoid processing later rules for this
-packet. The current status of the packet (after any effects of the
-current rule) will determine whether it is passed or blocked.

+# Allow all ICMP packets in

+Or at the end of a like, like this:

+.fi
+.SH Firewall rules
+.PP
+This section goes into detail on how to construct firewall rules that
+are placed in the ipf.conf file.
+.PP
+It is beyond the scope of this document to describe what makes a good
+firewall rule set or which packets should be blocked or allowed in.
+Some suggestions will be provided but further reading is expected to
+fully understand what is safe and unsafe to allow in/out.
+.SS Filter rule keywords
+.PP
+The first word found in any filter rule describes what the eventual outcome
+of a packet that matches it will be. Descriptions of the many and various
+sections that can be used to match on the contents of packet headers will
+follow on below.
+.PP
+The complete list of keywords, along with what they do is as follows:
+.RS
+.HP
+pass
+rules that match a packet indicate to ipfilter that it should be
+allowed to continue on in the direction it is flowing.
+.HP
+block
+rules are used when it is desirable to prevent a packet from going
+any further. Packets that are blocked on the "in" side are never seen by
+TCP/IP and those that are blocked going "out" are never seen on the wire.
+.HP
+log
+when IPFilter successfully matches a packet against a log rule a log
+record is generated and made available for ipmon(8) to read. These rules
+have no impact on whether or not a packet is allowed through or not.
+So if a packet first matched a block rule and then matched a log rule,
+the status of the packet after the log rule is that it will still be
+blocked.
+.HP
+count
+rules provide the administrator with the ability to count packets and
+bytes that match the criteria laid out in the configuration file.
+The count rules are applied after NAT and filter rules on the inbound
+path. For outbound packets, count rules are applied before NAT and
+before the packet is dropped. Thus the count rule cannot be used as
+a true indicator of link layer
+.HP
+auth
+rules cause the matching packet to be queued up for processing by a
+user space program. The user space program is responsible for making
+an ioctl system call to collect the information about the queued
+packet and another ioctl system call to return the verdict (block,
+pass, etc) on what to do with the packet. In the event that the queue
+becomes full, the packets will end up being dropped.
+.HP
+call
+provides access to functions built into IPFilter that allow for more
+complex actions to be taken as part of the decision making that goes
+with the rule.
+.HP
+decapsulate
+rules instruct ipfilter to remove any
+other headers (IP, UDP, AH) and then process what is inside as a new packet.
+For non-UDP packets, there are builtin checks that are applied in addition
+to whatever is specified in the rule, to only allow decapsulation of
+recognised protocols. After decapsulating the inner packet, any filtering
+result that is applied to the inner packet is also applied to the other
+packet.
+.PP
+The default way in which filter rules are applied is for the last
+matching rule to be used as the decision maker. So even if the first
+rule to match a packet is a pass, if there is a later matching rule
+that is a block and no further rules match the packet, then it will
+be blocked.
+.SS Matching Network Interfaces
+.PP
+On systems with more than one network interface, it is necessary
+to be able to specify different filter rules for each of them.
+In the first instance, this is because different networks will send us
+packets via each network interface but it is also because of the hosts,
+the role and the resulting security policy that we need to be able to
+distinguish which network interface a packet is on.
+.PP
+To accomodate systems where the presence of a network interface is
+dynamic, it is not necessary for the network interface named in a
+filter rule to be present in the system when the rule is loaded.
+This can lead to silent errors being introduced and unexpected
+behaviour with the simplest of keyboard mistakes - for example,
+typing in hem0 instead of hme0 or hme2 instead of hme3.
+.PP
+On Solaris systems prior to Solaris 10 Update 4, it is not possible
+to filter packets on the loopback interface (lo0) so filter rules
+that specify it will have no impact on the corresponding flow of
+packets. See below for Solaris specific tips on how to enable this.
+.PP
+Some examples of including the network interface in filter rules are:
+.PP
+.nf
+block in on bge0 all
+pass out on bge0 all
+.fi
+.SS Address matching (basic)
+.PP
+The first and most basic part of matching for filtering rules is to
+specify IP addresses and TCP/UDP port numbers. The source address
+information is matched by the "from" information in a filter rule
+and the destination address information is matched with the "to"
+information in a filter rule.
+.PP
+The typical format used for IP addresses is CIDR notation, where an
+IP address (or network) is followed by a '/' and a number representing
+the size of the netmask in bits. This notation is used for specifying
+address matching in both IPv4 and IPv6. If the '/' and bitmask size
+are excluded from the matching string, it is assumed that the address
+specified is a host address and that the netmask applied should be
+all 1's.
+.PP
+Some examples of this are:
+.PP
+.nf
+pass in from 10.1.0.0/24 to any
+block out from any to 10.1.1.1
+.fi
+.PP
+It is not possible to specify a range of addresses that does not

+.B Names instead of addresses
+.RS
+.PP
+Hostnames, resolved either via DNS or /etc/hosts, or network names,
+resolved via /etc/networks, may be used in place of actual addresses
+in the filter rules. WARNING: if a hostname expands to more than one
+address, only the *first* is used in building the filter rule.
+.PP
+Caution should be exercised when relying on DNS for filter rules in
+case the sending and receiving of DNS packets is blocked when ipf(8)
+is processing that part of the configuration file, leading to long
+delays, if not errors, in loading the filter rules.
+.RE
+.SS Protocol Matching
+.PP
+To match packets based on TCP/UDP port information, it is first necessary
+to indicate which protocol the packet must be. This is done using the
+"proto" keyword, followed by either the protocol number or a name which
+is mapped to the protocol number, usually through the /etc/protocols file.
+.PP
+.nf
+pass in proto tcp from 10.1.0.0/24 to any
+block out proto udp from any to 10.1.1.1
+pass in proto icmp from any to 192.168.0.0/16
+.fi
+.SS Sending back error packets
+.PP
+When a packet is just discarded using a block rule, there is no feedback given
+to the host that sent the packet. This is both good and bad. If this is the
+desired behaviour and it is not desirable to send any feedback about packets
+that are to be denied. The catch is that often a host trying to connect to a
+TCP port or with a UDP based application will send more than one packet
+because it assumes that just one packet may be discarded so a retry is
+required. The end result being logs can become cluttered with duplicate
+entries due to the retries.
+.PP
+To address this problem, a block rule can be qualified in two ways.
+The first of these is specific to TCP and instructs IPFilter to send back
+a reset (RST) packet. This packet indicates to the remote system that the
+packet it sent has been rejected and that it shouldn't make any further
+attempts to send packets to that port. Telling IPFilter to return a TCP
+RST packet in response to something that has been received is achieved
+with the return-rst keyword like this:
+.PP
+.nf
+block return-rst in proto tcp from 10.0.0.0/8 to any
+.fi
+.PP
+When sending back a TCP RST packet, IPFilter must construct a new packet
+that has the source address of the intended target, not the source address
+of the system it is running on (if they are different.)
+.PP
+For all of the other protocols handled by the IP protocol suite, to send
+back an error indicating that the received packet was dropped requires
+sending back an ICMP error packet. Whilst these can also be used for TCP,
+the sending host may not treat the received ICMP error as a hard error
+in the same way as it does the TCP RST packet. To return an ICMP error
+it is necessary to place return-icmp after the block keyword like this:
+.PP
+.nf
+block return-icmp in proto udp from any to 192.168.0.1/24
+.fi
+.PP
+When electing to return an ICMP error packet, it is also possible to
+select what type of ICMP error is returned. Whilst the full compliment
+of ICMP unreachable codes can be used by specifying a number instead of
+the string below, only the following should be used in conjunction with
+return-icmp. Which return code to use is a choice to be made when
+weighing up the pro's and con's. Using some of the codes may make it
+more obvious that a firewall is being used rather than just the host
+not responding.
+.RS
+.HP
+filter-prohib
+(prohibited by filter)
+sending packets to the destination given in the received packet is
+prohibited due to the application of a packet filter
+.HP
+net-prohib
+(prohibited network)
+sending packets to the destination given in the received packet is
+administratively prohibited.
+.HP
+host-unk
+(host unknown)
+the destination host address is not known by the system receiving
+the packet and therefore cannot be reached.
+.HP
+host-unr
+(host unreachable)
+it is not possible to reach the host as given by the destination address
+in the packet header.
+.HP
+net-unk
+(network unknown)
+the destination network address is not known by the system receiving
+the packet and therefore cannot be reached.
+.HP
+net-unr
+(network unreachable)
+it is not possible to forward the packet on to its final destination
+as given by the destination address
+.HP
+port-unr
+(port unreachable)
+there is no application using the given destination port and therefore
+it is not possible to reach that port.
+.HP
+proto-unr
+(protocol unreachable)
+the IP protocol specified in the packet is not available to receive
+packets.
+.DE
+.PP
+An example that shows how to send back a port unreachable packet for
+UDP packets to 192.168.1.0/24 is as follows:
+.PP
+.nf
+block return-icmp(port-unr) in proto udp from any to 192.168.1.0/24
+.fi
+.PP
+In the above examples, when sending the ICMP packet, IPFilter will construct
+a new ICMP packet with a source address of the network interface used to
+send the packet back to the original source. This can give away that there
+is an intermediate system blocking packets. To have IPFilter send back
+ICMP packets where the source address is the original destination, regardless
+of whether or not it is on the local host, return-icmp-as-dest is used like
+this:
+.PP
+.nf
+block return-icmp-as-dest(port-unr) in proto udp \\
+    from any to 192.168.1.0/24
+.fi
+.SS TCP/UDP Port Matching
+.PP
+Having specified which protocol is being matched, it is then possible to
+indicate which port numbers a packet must have in order to match the rule.
+Due to port numbers being used differently to addresses, it is therefore
+possible to match on them in different ways. IPFilter allows you to use
+the following logical operations:
+.IP "< x"
+is true if the port number is greater than or equal to x and less than or
+equal to y
+is true if the port number in the packet is less than x
+.IP "<= x"
+is true if the port number in the packet is less than or equal to x
+.IP "> x"
+is true if the port number in the packet is greater than x
+.IP ">= x"
+is true if the port number in the packet is greater or equal to x
+.IP "= x"
+is true if the port number in the packet is equal to x
+.IP "!= x"
+is true if the port number in the packet is not equal to x
+.PP
+Additionally, there are a number of ways to specify a range of ports:
+.IP "x <> y"
+is true if the port number is less than a and greater than y
+.IP "x >< y"
+is true if the port number is greater than x and less than y
+.IP "x:y"
+is true if the port number is greater than or equal to x and less than or
+equal to y
+.PP
+Some examples of this are:
+.PP
+.nf
+block in proto tcp from any port >= 1024 to any port < 1024
+pass in proto tcp from 10.1.0.0/24 to any port = 22
+block out proto udp from any to 10.1.1.1 port = 135
+pass in proto udp from 1.1.1.1 port = 123 to 10.1.1.1 port = 123
+pass in proto tcp from 127.0.0.0/8 to any port = 6000:6009
+.fi
+.PP
+If there is no desire to mention any specific source or destintion
+information in a filter rule then the word "all" can be used to
+indicate that all addresses are considered to match the rule.
+.SS IPv4 or IPv6
+.PP
+If a filter rule is constructed without any addresses then IPFilter
+will attempt to match both IPv4 and IPv6 packets with it. In the
+next list of rules, each one can be applied to either network protocol
+because there is no address specified from which IPFilter can derive
+with network protocol to expect.
+.PP
+.nf
+pass in proto udp from any to any port = 53
+block in proto tcp from any port < 1024 to any
+.fi
+.PP
+To explicitly match a particular network address family with a specific
+rule, the family must be added to the rule. For IPv4 it is necessary to
+add family inet and for IPv6, family inet6. Thus the next rule will
+block all packets (both IPv4 and IPv6:
+.PP
+.nf
+block in all
+.fi
+.PP
+but in the following example, we block all IPv4 packets and only allow
+in IPv6 packets:
+.PP
+.nf
+block in family inet all
+pass in family inet6 all
+.fi
+.PP
+To continue on from the example where we allowed either IPv4 or IPv6
+packets to port 53 in, to change that such that only IPv6 packets to
+port 53 need to allowed blocked then it is possible to add in a
+protocol family qualifier:
+.PP
+.nf
+pass in family inet6 proto udp from any to any port = 53
+.fi
+.SS First match vs last match
+.PP
+To change the default behaviour from being the last matched rule decides
+the outcome to being the first matched rule, the word "quick" is inserted
+to the rule.
+.SH Extended Packet Matching
+.SS Beyond using plain addresses
+.PP
+On firewalls that are working with large numbers of hosts and networks
+or simply trying to filter discretely against various hosts, it can
+be an easier administration task to define a pool of addresses and have
+a filter rule reference that address pool rather than have a rule for
+each address.
+.PP
+In addition to being able to use address pools, it is possible to use
+the interface name(s) in the from/to address fields of a rule. If the
+name being used in the address section can be matched to any of the
+interface names mentioned in the rule's "on" or "via" fields then it
+can be used with one of the following keywords for extended effect:
+.HP
+broadcast
+use the primary broadcast address of the network interface for matching
+packets with this filter rule;
 .IP
-If this option is missing, the rule is taken to be a "fall-through"
-rule, meaning that the result of the match (block/pass) is saved and
-that processing will continue to see if there are any more matches.
-.TP
-.B on
-allows an interface name to be incorporated into the matching
-procedure. Interface names are as printed by "netstat \-i". If this
-option is used, the rule will only match if the packet is going
-through that interface in the specified direction (in/out). If this
-option is absent, the rule is taken to be applied to a packet
-regardless of the interface it is present on (i.e. on all interfaces).
-Filter rulesets are common to all interfaces, rather than having a
-filter list for each interface.
+.nf
+pass in on fxp0 proto udp from any to fxp0/broadcast port = 123
+.fi
+.HP
+peer
+use the peer address on point to point network interfaces for matching
+packets with this filter rule. This option typically only has meaningful
+use with link protocols such as SLIP and PPP.
+For example, this rule allows ICMP packets from the remote peer of ppp0
+to be received if they're destined for the address assigned to the link
+at the firewall end.
 .IP
-This option is especially useful for simple IP-spoofing protection:
-packets should only be allowed to pass inbound on the interface from
-which the specified source address would be expected, others may be
-logged and/or dropped.
-.TP
-.B dup-to
-causes the packet to be copied, and the duplicate packet to be sent
-outbound on the specified interface, optionally with the destination
-IP address changed to that specified. This is useful for off-host
-logging, using a network sniffer.
-.TP
-.B to
-causes the packet to be moved to the outbound queue on the
-specified interface. This can be used to circumvent kernel routing
-decisions, and even to bypass the rest of the kernel processing of the
-packet (if applied to an inbound rule). It is thus possible to
-construct a firewall that behaves transparently, like a filtering hub
-or switch, rather than a router. The \fBfastroute\fP keyword is a
-synonym for this option.
-.SH MATCHING PARAMETERS
-.PP 
-The keywords described in this section are used to describe attributes
-of the packet to be used when determining whether rules match or don't
-match. The following general-purpose attributes are provided for
-matching, and must be used in this order:
-.TP
-.B tos
-packets with different Type-Of-Service values can be filtered.
-Individual service levels or combinations can be filtered upon.  The
-value for the TOS mask can either be represented as a hex number or a
-decimal integer value.
-.TP
-.B ttl
-packets may also be selected by their Time-To-Live value.  The value given in
-the filter rule must exactly match that in the packet for a match to occur.
-This value can only be given as a decimal integer value.
-.TP
-.B proto
-allows a specific protocol to be matched against.  All protocol names
-found in \fB/etc/protocols\fP are recognised and may be used.
-However, the protocol may also be given as a DECIMAL number, allowing
-for rules to match your own protocols, or new ones which would
-out-date any attempted listing.
+.nf
+pass in on ppp0 proto icmp from ppp0/peer to ppp0/32
+.fi
+.HP
+netmasked
+use the primary network address, with its netmask, of the network interface
+for matching packets with this filter rule. If a network interface had an
+IP address of 192.168.1.1 and its netmask was 255.255.255.0 (/24), then
+using the word "netmasked" after the interface name would match any
+addresses that would match 192.168.1.0/24. If we assume that bge0 has
+this IP address and netmask then the following two rules both serve
+to produce the same effect:
 .IP
-The special protocol keyword \fBtcp/udp\fP may be used to match either
-a TCP or a UDP packet, and has been added as a convenience to save
-duplication of otherwise-identical rules.
-.\" XXX grammar should reflect this (/etc/protocols)
-.PP
-The \fBfrom\fP and \fBto\fP keywords are used to match against IP
-addresses (and optionally port numbers). Rules must specify BOTH
-source and destination parameters.
-.PP 
-IP addresses may be specified in one of two ways: as a numerical
-address\fB/\fPmask, or as a hostname \fBmask\fP netmask.  The hostname
-may either be a valid hostname, from either the hosts file or DNS
-(depending on your configuration and library) or of the dotted numeric
-form.  There is no special designation for networks but network names
-are recognised.  Note that having your filter rules depend on DNS
-results can introduce an avenue of attack, and is discouraged.
-.PP
-There is a special case for the hostname \fBany\fP which is taken to
-be 0.0.0.0/0 (see below for mask syntax) and matches all IP addresses.
-Only the presence of "any" has an implied mask, in all other
-situations, a hostname MUST be accompanied by a mask.  It is possible
-to give "any" a hostmask, but in the context of this language, it is
-non-sensical.
-.PP
-The numerical format "x\fB/\fPy" indicates that a mask of y
-consecutive 1 bits set is generated, starting with the MSB, so a y value
-of 16 would give 0xffff0000. The symbolic "x \fBmask\fP y" indicates
-that the mask y is in dotted IP notation or a hexadecimal number of
-the form 0x12345678.  Note that all the bits of the IP address
-indicated by the bitmask must match the address on the packet exactly;
-there isn't currently a way to invert the sense of the match, or to
-match ranges of IP addresses which do not express themselves easily as
-bitmasks (anthropomorphization; it's not just for breakfast anymore).
-.PP
-If a \fBport\fP match is included, for either or both of source and
-destination, then it is only applied to
-.\" XXX - "may only be" ? how does this apply to other protocols? will it not match, or will it be ignored?
-TCP and UDP packets. If there is no \fBproto\fP match parameter,
-packets from both protocols are compared. This is equivalent to "proto
-tcp/udp".  When composing \fBport\fP comparisons, either the service
-name or an integer port number may be used. Port comparisons may be
-done in a number of forms, with a number of comparison operators, or
-port ranges may be specified. When the port appears as part of the
-\fBfrom\fP object, it matches the source port number, when it appears
-as part of the \fBto\fP object, it matches the destination port number.
-See the examples for more information.
-.PP
-The \fBall\fP keyword is essentially a synonym for "from any to any"
-with no other match parameters.
-.PP
-Following the source and destination matching parameters, the
-following additional parameters may be used:
-.TP
-.B with
-is used to match irregular attributes that some packets may have
-associated with them.  To match the presence of IP options in general,
-use \fBwith ipopts\fP. To match packets that are too short to contain
-a complete header, use \fBwith short\fP. To match fragmented packets,
-use \fBwith frag\fP.  For more specific filtering on IP options,
-individual options can be listed.
+.nf
+pass in on bge0 proto icmp from any to 192.168.1.0/24
+pass in on bge0 proto icmp from any to bge0/netmasked
+.fi
+.HP
+network
+using the primary network address, and its netmask, of the network interface,
+construct an address for exact matching. If a network interface has an
+address of 192.168.1.1 and its netmask is 255.255.255.0, using this
+option would only match packets to 192.168.1.0.
 .IP
-Before any parameter used after the \fBwith\fP keyword, the word
-\fBnot\fP or \fBno\fP may be inserted to cause the filter rule to only
-match if the option(s) is not present.
+.nf
+pass in on bge0 proto icmp from any to bge0/network
+.fi
+.PP
+Another way to use the name of a network interface to get the address
+is to wrap the name in ()'s. In the above method, IPFilter
+looks at the interface names in use and to decide whether or not
+the name given is a hostname or network interface name. With the
+use of ()'s, it is possible to tell IPFilter that the name should
+be treated as a network interface name even though it doesn't
+appear in the list of network interface that the rule ias associated
+with.
 .IP
-Multiple consecutive \fBwith\fP clauses are allowed.  Alternatively,
-the keyword \fBand\fP may be used in place of \fBwith\fP, this is
-provided purely to make the rules more readable ("with ... and ...").
-When multiple clauses are listed, all those must match to cause a
-match of the rule.
-.\" XXX describe the options more specifically in a separate section
-.TP
-.B flags
-is only effective for TCP filtering.  Each of the letters possible
-represents one of the possible flags that can be set in the TCP
-header.  The association is as follows:
-.LP
-.nf
-        F - FIN
-        S - SYN
-        R - RST
-        P - PUSH
-        A - ACK
-        U - URG
+.nf
+pass in proto icmp from any to (bge0)/32
+.fi
+.SS Using address pools
+.PP
+Rather than list out multiple rules that either allow or deny specific
+addresses, it is possible to create a single object, call an address
+pool, that contains all of those addresses and reference that in the
+filter rule. For documentation on how to write the configuration file
+for those pools and load them, see ippool.conf(5) and ippool(8).
+There are two types of address pools that can be defined in ippool.conf(5):
+trees and hash tables. To refer to a tree defined in ippool.conf(5),
+use this syntax:
+.PP
+.nf
+pass in from pool/trusted to any
 .fi
+.PP
+Either a name or number can be used after the '/', just so long as it
+matches up with something that has already been defined in ipool.conf(5)
+and loaded in with ippool(8). Loading a filter rule that references a
+pool that does not exist will result in an error.
+.PP
+If hash tables have been used in ippool.conf(5) to store the addresses
+in instead of a tree, then replace the word pool with hash:
 .IP
-The various flag symbols may be used in combination, so that "SA"
-would represent a SYN-ACK combination present in a packet.  There is
-nothing preventing the specification of combinations, such as "SFR",
-that would not normally be generated by law-abiding TCP
-implementations.  However, to guard against weird aberrations, it is
-necessary to state which flags you are filtering against.  To allow
-this, it is possible to set a mask indicating which TCP flags you wish
-to compare (i.e., those you deem significant).  This is done by
-appending "/<flags>" to the set of TCP flags you wish to match
-against, e.g.:
-.LP
-.nf
-	... flags S
-			# becomes "flags S/AUPRFS" and will match
-			# packets with ONLY the SYN flag set.
-
-	... flags SA
-			# becomes "flags SA/AUPRFS" and will match any
-			# packet with only the SYN and ACK flags set.
+.nf
+pass in from any to hash/webservers
+.fi
+.PP
+There are different operational characteristics with each, so there
+may be some situations where a pool works better than hash and vice
+versa.
+.SS Matching TCP flags
+.PP
+The TCP header contains a field of flags that is used to decide if the
+packet is a connection request, connection termination, data, etc.
+By matching on the flags in conjunction with port numbers, it is
+possible to restrict the way in which IPFilter allows connections to
+be created.  A quick overview of the TCP
+flags is below. Each is listed with the letter used in IPFilter
+rules, followed by its three or four letter pneumonic.
+.HP
+S
+SYN - this bit is set when a host is setting up a connection.
+The initiator typically sends a packet with the SYN bit and the
+responder sends back SYN plus ACK.
+.HP
+A
+ACK - this bit is set when the sender wishes to acknowledge the receipt
+of a packet from another host
+.HP
+P
+PUSH - this bit is set when a sending host has send some data that
+is yet to be acknowledged and a reply is sought
+.HP
+F
+FIN - this bit is set when one end of a connection starts to close
+the connection down
+.HP
+U
+URG - this bit is set to indicate that the packet contains urgent data
+.HP
+R
+RST - this bit is set only in packets that are a reply to another
+that has been received but is not targetted at any open port
+.HP
+C
+CWN
+.HP
+E
+ECN
+.PP
+When matching TCP flags, it is normal to just list the flag that you
+wish to be set. By default the set of flags it is compared against
+is "FSRPAU". Rules that say "flags S" will be displayed by ipfstat(8)
+as having "flags S/FSRPAU". This is normal.
+The last two flags, "C" and "E", are optional - they
+may or may not be used by an end host and have no bearing on either
+the acceptance of data nor control of the connection. Masking them
+out with "flags S/FSRPAUCE" may cause problems for remote hosts
+making a successful connection.
+.PP
+.nf
+pass in quick proto tcp from any to any port = 22 flags S/SAFR
+pass out quick proto tcp from any port = 22 to any flags SA
+.fi
+.PP
+By itself, filtering based on the TCP flags becomes more work but when
+combined with stateful filtering (see below), the situation changes.
+.SS Matching on ICMP header information
+.PP
+The TCP and UDP are not the only protocols for which filtering beyond
+just the IP header is possible, extended matching on ICMP packets is
+also available. The list of valid ICMP types is different for IPv4
+vs IPv6.
+.PP
+As a practical example, to allow the ping command to work
+against a specific target requires allowing two different types of
+ICMP packets, like this:
+.PP
+.nf
+pass in proto icmp from any to webserver icmp-type echo
+pass out proto icmp from webserver to any icmp-type echorep
+.fi
+.PP
+The ICMP header has two fields that are of interest for filtering:
+the ICMP type and code. Filter rules can accept either a name or
+number for both the type and code. The list of names supported for
+ICMP types is listed below, however only ICMP unreachable errors
+have named codes (see above.)
+.PP
+The list of ICMP types that are available for matching an IPv4 packet
+are as follows:
+.PP
+echo (echo request),
+echorep (echo reply),
+inforeq (information request),
+inforep (information reply),
+maskreq (mask request),
+maskrep (mask reply),
+paramprob (parameter problem),
+redir (redirect),
+routerad (router advertisement),
+routersol (router solicit),
+squence (source quence),
+timest (timestamp),
+timestreq (timestamp reply),
+timex (time exceeded),
+unreach (unreachable).
+.PP
+The list of ICMP types that are available for matching an IPv6 packet
+are as follows:
+.PP
+echo (echo request),
+echorep (echo reply),
+fqdnquery (FQDN query),
+fqdnreply (FQDN reply),
+inforeq (information request),
+inforep (information reply),
+listendone (MLD listener done),
+listendqry (MLD listener query),
+listendrep (MLD listener reply),
+neighadvert (neighbour advert),
+neighborsol (neighbour solicit),
+paramprob (parameter problem),
+redir (redirect),
+renumber (router renumbering),
+routerad (router advertisement),
+routersol (router solicit),
+timex (time exceeded),
+toobig (packet too big),
+unreach (unreachable,
+whoreq (WRU request),
+whorep (WRU reply).
+.SH Stateful Packet Filtering
+.PP
+Stateful packet filtering is where IPFilter remembers some information from
+one or more packets that it has seen and is able to apply it to future
+packets that it receives from the network.
+.PP
+What this means for each transport layer protocol is different.
+For TCP it means that if IPFilter
+sees the very first packet of an attempt to make a connection, it has enough
+information to allow all other subsequent packets without there needing to
+be any explicit rules to match them. IPFilter uses the TCP port numbers,
+TCP flags, window size and sequence numbers to determine which packets
+should be matched. For UDP, only the UDP port numbers are available.
+For ICMP, the ICMP types can be combined with the ICMP id field to
+determine which reply packets match a request/query that has already
+been seen. For all other protocols, only matching on IP address and
+protocol number is available for determining if a packet received is a mate
+to one that has already been let through.
+.PP
+The difference this makes is a reduction in the number of rules from
+2 or 4 to 1. For example, these 4 rules:
+.PP
+.nf
+pass in on bge0 proto tcp from any to any port = 22
+pass out on bge1 proto tcp from any to any port = 22
+pass in on bge1 proto tcp from any port = 22 to any
+pass out on bge0 proto tcp from any port = 22 to any
+.fi
+.PP
+can be replaced with this single rule:
+.PP
+.nf
+pass in on bge0 proto tcp from any to any port = 22 flags S keep state
+.fi
+.PP
+Similar rules for UDP and ICMP might be:
+.PP
+.nf
+pass in on bge0 proto udp from any to any port = 53 keep state
+pass in on bge0 proto icmp all icmp-type echo keep state
+.fi
+.PP
+When using stateful filtering with TCP it is best to add "flags S" to the
+rule to ensure that state is only created when a packet is seen that is
+an indication of a new connection. Although IPFilter can gather some
+information from packets in the middle of a TCP connection to do stateful
+filtering, there are some options that are only sent at the start of the
+connection which alter the valid window of what TCP accepts. The end result
+of trying to pickup TCP state in mid connection is that some later packets
+that are part of the connection may not match the known state information
+and be dropped or blocked, causing problems. If a TCP packet matches IP
+addresses and port numbers but does not fit into the recognised window,
+it will not be automatically allowed and will be flagged inside of
+IPFitler as "out of window" (oow). See below, "Extra packet attributes",
+for how to match on this attribute.
+.PP
+Once a TCP connection has reached the established state, the default
+timeout allows for it to be idle for 5 days before it is removed from
+the state table. The timeouts for the other TCP connection states
+vary from 240 seconds to 30 seconds.
+Both UDP and ICMP state entries have asymetric timeouts where the timeout
+set upon seeing packets in the forward direction is much larger than
+for the reverse direction. For UDP the default timeouts are 120 and
+12 seconds, for ICMP 60 and 6 seconds. This is a reflection of the
+use of these protocols being more for query-response than for ongoing
+connections.  For all other protocols the
+timeout is 60 seconds in both directions.
+.SS Stateful filtering options
+.PP
+The following options can be used with stateful filtering:
+.HP
+limit
+limit the number of state table entries that this rule can create to
+the number given after limit. A rule that has a limit specified is
+always permitted that many state table entries, even if creating an
+additional entry would cause the table to have more entries than the
+otherwise global limit.
+.IP
+.nf
+pass ... keep state(limit 100)
+.fi
+.HP
+age
+sets the timeout for the state entry when it sees packets going through
+it. Additionally it is possible to set the tieout for the reply packets
+that come back through the firewall to a different value than for the
+forward path. allowing a short timeout to be set after the reply has
+been seen and the state no longer required.
+.RS
+.PP
+.nf
+pass in quick proto icmp all icmp-type echo \\
+    keep state (age 3)
+pass in quick proto udp from any \\
+    to any port = 53 keep state (age 30/1)
+.fi
+.RE
+.HP
+strict
+only has an impact when used with TCP. It forces all packets that are
+allowed through the firewall to be sequential: no out of order delivery
+of packets is allowed. This can cause significant slowdown for some
+connections and may stall others. Use with caution.
+.IP
+.nf
+pass in proto tcp ... keep state(strict)
+.fi
+.HP
+noicmperr
+prevents ICMP error packets from being able to match state table entries
+created with this flag using the contents of the original packet included.
+.IP
+.nf
+pass ... keep state(noicmperr)
+.fi
+.HP
+sync
+indicates to IPFilter that it needs to provide information to the user
+land daemons responsible for syncing other machines state tables up
+with this one.
+.IP
+.nf
+pass ... keep state(sync)
+.fi
+.HP
+nolog
+do not generate any log records for the creation or deletion of state
+table entries.
+.IP
+.nf
+pass ... keep state(nolog)
+.fi
+.HP
+icmp-head
+rather than just precent ICMP error packets from being able to match
+state table entries, allow an ACL to be processed that can filter in or
+out ICMP error packets based as you would with normal firewall rules.
+The icmp-head option requires a filter rule group number or name to
+be present, just as you would use with head.
+.RS
+.PP
+.nf
+pass in quick proto tcp ... keep state(icmp-head 101)
+block in proto icmp from 10.0.0.0/8 to any group 101
+.fi
+.RE
+.HP
+max-srcs
+allows the number of distinct hosts that can create a state entry to
+be defined.
+.IP
+.nf
+pass ... keep state(max-srcs 100)
+pass ... keep state(limit 1000, max-srcs 100)
+.fi
+.HP
+max-per-src
+whilst max-srcs limits the number of individual hosts that may cause
+the creation of a state table entry, each one of those hosts is still
+table to fill up the state table with new entries until the global
+maximum is reached. This option allows the number of state table entries
+per address to be limited.
+.IP
+.nf
+pass ... keep state(max-srcs 100, max-per-src 1)
+pass ... keep state(limit 100, max-srcs 100, max-per-src 1)
+.fi
+.IP
+Whilst these two rules might seem identical, in that they both
+ultimately limit the number of hosts and state table entries created
+from the rule to 100, there is a subtle difference: the second will
+always allow up to 100 state table entries to be created whereas the
+first may not if the state table fills up from other rules.
+.IP
+Further, it is possible to specify a netmask size after the per-host
+limit that enables the per-host limit to become a per-subnet or
+per-network limit.
+.IP
+.nf
+pass ... keep state(max-srcs 100, max-per-src 1/24)
+.fi
+.IP
+If there is no IP protocol implied by addresses or other features of
+the rule, IPFilter will assume that no netmask is an all ones netmask
+for both IPv4 and IPv6.
+.SS Tieing down a connection
+.PP
+For any connection that transits a firewall, each packet will be seen
+twice: once going in and once going out. Thus a connection has 4 flows
+of packets:
+.HP
+forward
+inbound packets
+.HP
+forward
+outbound packets
+.HP
+reverse
+inbound packets
+.HP
+reverse
+outbound packets
+.PP
+IPFilter allows you to define the network interface to be used at all
+four points in the flow of packets. For rules that match inbound packets,
+out-via is used to specify which interfaces the packets go out, For rules
+that match outbound packets, in-via is used to match the inbound packets.
+In each case, the syntax generalises to this:
+.PP
+.nf
+pass ... in on forward-in,reverse-in \\
+       out-via forward-out,reverse-out ...
 
-	... flags S/SA
-			# will match any packet with just the SYN flag set
-			# out of the SYN-ACK pair; the common "establish"
-			# keyword action.  "S/SA" will NOT match a packet
-			# with BOTH SYN and ACK set, but WILL match "SFP".
-.fi
-.TP
-.B icmp-type
-is only effective when used with \fBproto icmp\fP and must NOT be used
-in conjunction with \fBflags\fP.  There are a number of types, which can be
-referred to by an abbreviation recognised by this language, or the numbers
-with which they are associated can be used.  The most important from
-a security point of view is the ICMP redirect.
-.SH KEEP HISTORY
-.PP
-The second last parameter which can be set for a filter rule is whether or not
-to record historical information for that packet, and what sort to keep. The
-following information can be kept:
-.TP
-.B state
-keeps information about the flow of a communication session. State can
-be kept for TCP, UDP, and ICMP packets.
-.TP
-.B frags
-keeps information on fragmented packets, to be applied to later
-fragments.
-.PP
-allowing packets which match these to flow straight through, rather
-than going through the access control list.
-.SH GROUPS
-The last pair of parameters control filter rule "grouping".  By default, all
-filter rules are placed in group 0 if no other group is specified.  To add a
-rule to a non-default group, the group must first be started by creating a
-group \fIhead\fP.  If a packet matches a rule which is the \fIhead\fP of a
-group, the filter processing then switches to the group, using that rule as
-the default for the group.  If \fBquick\fP is used with a \fBhead\fP rule, rule
-processing isn't stopped until it has returned from processing the group.
-.PP
-A rule may be both the head for a new group and a member of a non-default
-group (\fBhead\fP and \fBgroup\fP may be used together in a rule).
-.TP
-.B "head <n>"
-indicates that a new group (number n) should be created.
-.TP
-.B "group <n>"
-indicates that the rule should be put in group (number n) rather than group 0.
-.SH LOGGING
-.PP
-When a packet is logged, with either the \fBlog\fP action or option,
-the headers of the packet are written to the \fBipl\fP packet logging
-pseudo-device. Immediately following the \fBlog\fP keyword, the
-following qualifiers may be used (in order):
-.TP
-.B body
-indicates that the first 128 bytes of the packet contents will be
-logged after the headers. 
-.TP
-.B first
-If log is being used in conjunction with a "keep" option, it is recommended
-that this option is also applied so that only the triggering packet is logged
-and not every packet which thereafter matches state information.
-.TP
-.B or-block
-indicates that, if for some reason the filter is unable to log the
-packet (such as the log reader being too slow) then the rule should be
-interpreted as if the action was \fBblock\fP for this packet.
-.TP
-.B "level <loglevel>"
-indicates what logging facility and priority, or just priority with
-the default facility being used, will be used to log information about 
-this packet using ipmon's -s option.
-.PP
-See ipl(4) for the format of records written
-to this device. The ipmon(8) program can be used to read and format
-this log.
-.SH EXAMPLES
-.PP
-The \fBquick\fP option is good for rules such as:
-\fC
-.nf
-block in quick from any to any with ipopts
-.fi
-.PP
-which will match any packet with a non-standard header length (IP
-options present) and abort further processing of later rules,
-recording a match and also that the packet should be blocked.
-.PP
-The "fall-through" rule parsing allows for effects such as this:
-.LP
-.nf
-        block in from any to any port < 6000
-        pass in from any to any port >= 6000
-        block in from any to any port > 6003
-.fi
-.PP
-which sets up the range 6000-6003 as being permitted and all others being
-denied.  Note that the effect of the first rule is overridden by subsequent
-rules.  Another (easier) way to do the same is:
-.LP
-.nf
-        block in from any to any port 6000 <> 6003
-        pass in from any to any port 5999 >< 6004
-.fi
-.PP
-Note that both the "block" and "pass" are needed here to effect a
-result as a failed match on the "block" action does not imply a pass,
-only that the rule hasn't taken effect.  To then allow ports < 1024, a
-rule such as:
-.LP
-.nf
-        pass in quick from any to any port < 1024
-.fi
-.PP
-would be needed before the first block.  To create a new group for
-processing all inbound packets on le0/le1/lo0, with the default being to block
-all inbound packets, we would do something like:
-.LP
-.nf
-       block in all
-       block in quick on le0 all head 100
-       block in quick on le1 all head 200
-       block in quick on lo0 all head 300
+pass ... out on forward-out,reverse-out \\
+         in-via forward-in,reverse-in ...
+.fi
+.PP
+An example that pins down all 4 network interfaces used by an ssh
+connection might look something like this:
+.PP
+.nf
+pass in on bge0,bge1 out-via bge1,bge0 proto tcp \\
+    from any to any port = 22 flags S keep state
+.fi
+.SS Working with packet fragments
+.PP
+Fragmented packets result in 1 packet containing all of the layer 3 and 4
+header information whilst the data is split across a number of other packets.
+.PP
+To enforce access control on fragmented packets, one of two approaches
+can be taken. The first is to allow through all of the data fragments
+(those that made up the body of the original packet) and rely on matching
+the header information in the "first" fragment, when it is seen. The
+reception of body fragments without the first will result in the receiving
+host being unable to completely reassemble the packet and discarding all
+of the fragments. The following three rules deny all fragmented packets
+from being received except those that are UDP and even then only allows
+those destined for port 2049 to be completed.
+.PP
+.nf
+block in all with frags
+pass in proto udp from any to any with frag-body
+pass in proto udp from any to any port = 2049 with frags
+.fi
+.PP
+Another mechanism that is available is to track "fragment state".
+This relies on the first fragment of a packet that arrives to be
+the fragment that contains all of the layer 3 and layer 4 header
+information. With the receipt of that fragment before any other,
+it is possible to determine which other fragments are to be allowed
+through without needing to explicitly allow all fragment body packets.
+An example of how this is done is as follows:
+.PP
+.nf
+pass in proto udp from any prot = 2049 to any with frags keep fags
+.fi
+.SH Building a tree of rules
+.PP
+Writing your filter rules as one long list of rules can be both inefficient
+in terms of processing the rules and difficult to understand. To make the
+construction of filter rules easier, it is possible to place them in groups.
+A rule can be both a member of a group and the head of a new group.
+.PP
+Using filter groups requires at least two rules: one to be in the group
+one one to send matchign packets to the group. If a packet matches a
+filtre rule that is a group head but does not match any of the rules
+in that group, then the packet is considered to have matched the head
+rule.
+.PP
+Rules that are a member of a group contain the word group followed by
+either a name or number that defines which group they're in. Rules that
+form the branch point or starting point for the group must use the
+word head, followed by either a group name or number. If rules are
+loaded in that define a group but there is no matching head then they
+will effectively be orphaned rules. It is possible to have more than
+one head rule point to the same group, allowing groups to be used
+like subroutines to implement specific common policies.
+.PP
+A common use of filter groups is to define head rules that exist in the
+filter "main line" for each direction with the interfaces in use. For
+example:
+.PP
+.nf
+block in quick on bge0 all head 100
+block out quick on bge0 all head 101
+block in quick on fxp0 all head internal-in
+block out quick on fxp0 all head internal-out
+pass in quick proto icmp all icmp-type echo group 100
+.fi
+.PP
+In the above set of rules, there are four groups defined but only one
+of them has a member rule. The only packets that would be allowed
+through the above ruleset would be ICMP echo packets that are
+received on bge0.
+.PP
+Rules can be both a member of a group and the head of a new group,
+allowing groups to specialise.
+.PP
+.nf
+block in quick on bge0 all head 100
+block in quick proto tcp all head 1006 group 100
+.fi
+.PP
+Another use of filter rule groups is to provide a place for rules to
+be dynamically added without needing to worry about their specific
+ordering amongst the entire ruleset. For example, if I was using this
+simple ruleset:
+.PP
+.nf
+block in quick all with bad
+block in proto tcp from any to any port = smtp head spammers
+pass in quick proto tcp from any to any port = smtp flags S keep state
+.fi
+.PP
+and I was getting lots of connections to my email server from 10.1.1.1
+to deliver spam, I could load the following rule to complement the above:
+.IP
+.nf
+block in quick from 10.1.1.1 to any group spammers
 .fi
+.SS Decapsulation
 .PP
+Rule groups also form a different but vital role for decapsulation rules.
+With the following simple rule, if IPFilter receives an IP packet that has
+an AH header as its layer 4 payload, IPFilter would adjust its view of the
+packet internally and then jump to group 1001 using the data beyond the
+AH header as the new transport header.
+.PP
+.nf
+decapsulate in proto ah all head 1001
+.fi
+.PP
+For protocols that
+are recognised as being used with tunnelling or otherwise encapsulating
+IP protocols, IPFilter is able to decide what it has on the inside
+without any assistance. Some tunnelling protocols use UDP as the
+transport mechanism. In this case, it is necessary to instruct IPFilter
+as to what protocol is inside UDP.
+.PP
+.nf
+decapsulate l5-as(ip) in proto udp from any \\
+    to any port = 1520 head 1001
+.fi
+.PP
+Currently IPFilter only supports finding IPv4 and IPv6 headers
+directly after the UDP header.
+.PP
+If a packet matches a decapsulate rule but fails to match any of the rules
+that are within the specified group, processing of the packet continues
+to the next rule after the decapsulate and IPFilter's internal view of the
+packet is returned to what it was prior to the decapsulate rule.
+.PP
+It is possible to construct a decapsulate rule without the group
+head at the end that ipf(8) will accept but such rules will not
+result in anything happening.
+.SS Policy Based Routing
+.PP
+With firewalls being in the position they often are, at the boundary
+of different networks connecting together and multiple connections that
+have different properties, it is often desirable to have packets flow
+in a direction different to what the routing table instructs the kernel.
+These decisions can often be extended to changing the route based on
+both source and destination address or even port numbers.
+.PP
+To support this kind of configuration, IPFilter allows the next hop
+destination to be specified with a filter rule. The next hop is given
+with the interface name to use for output. The syntax for this is
+interface:ip.address. It is expected that the address given as the next
+hop is directly connected to the network to which the interface is.
+.PP
+.nf
+pass in on bge0 to bge1:1.1.1.1 proto tcp \\
+    from 1.1.2.3 to any port = 80 flags S keep state
+.fi
+.PP
+When this feature is combined with stateful filtering, it becomes
+possible to influence the network interface used to transmit packets
+in both directions because we now have a sense for what its reverse
+flow of packets is.
+.PP
+.nf
+pass in on bge0 to bge1:1.1.1.1 reply-to hme1:2.1.1.2 \\
+    proto tcp from 1.1.2.3 to any port = 80 flags S keep state
+.fi
+.PP
+If the actions of the routing table are perfectly acceptable, but
+you would like to mask the presence of the firewall by not changing
+the TTL in IP packets as they transit it, IPFilter can be instructed
+to do a "fastroute" action like this:
+.PP
+.nf
+pass in on bge0 fastroute proto icmp all
+.fi
+.PP
+This should be used with caution as it can lead to endless packet
+loops. Additionally, policy based routing does not change the IP
+header's TTL value.
+.PP
+A variation on this type of rule supports a duplicate of the original
+packet being created and sent out a different network. This can be
+useful for monitoring traffic and other purposes.
+.PP
+.nf
+pass in on bge0 to bge1:1.1.1.1 reply-to hme1:2.1.1.2 \\
+    dup-to fxp0:10.0.0.1 proto tcp from 1.1.2.3 \\
+    to any port = 80 flags S keep state
+.fi
+.SS Matching IPv4 options
+.PP
+The design for IPv4 allows for the header to be upto 64 bytes long,
+however most traffic only uses the basic header which is 20 bytes long.
+The other 44 bytes can be uesd to store IP options. These options are
+generally not necessary for proper interaction and function on the
+Internet today. For most people it is sufficient to block and drop
+all packets that have any options set. This can be achieved with this
+rule:
+.PP
+.nf
+block in quick all with ipopts
+.fi
+.PP
+This rule is usually placed towards the top of the configuration
+so that all incoming packets are blocked.
+.PP
+If you wanted to allow in a specific IP option type, the syntax
+changes slightly:
+.PP
+.nf
+pass in quick proto igmp all with opt rtralrt
+.fi
+.PP
+The following is a list of IP options that most people encounter and
+what their use/threat is.
+.HP
+lsrr
+(loose source route) the sender of the packet includes a list of addresses
+that they wish the packet to be routed through to on the way to the
+destination. Because replies to such packets are expected to use the
+list of addresses in reverse, hackers are able to very effectively use
+this header option in address spoofing attacks.
+.HP
+rr
+(record route) the sender allocates some buffer space for recording the
+IP address of each router that the packet goes through. This is most often
+used with ping, where the ping response contains a copy of all addresses
+from the original packet, telling the sender what route the packet took
+to get there. Due to performance and security issues with IP header
+options, this is almost no longer used.
+.HP
+rtralrt
+(router alert) this option is often used in IGMP messages as a flag to
+routers that the packet needs to be handled differently. It is unlikely
+to ever be received from an unknown sender. It may be found on LANs or
+otherwise controlled networks where the RSVP protocol and multicast
+traffic is in heavy use.
+.HP
+ssrr
+(strict source route) the sender of the packet includes a list of addresses
+that they wish the packet to be routed through to on the way to the
+destination. Where the lsrr option allows the sender to specify only
+some of the nodes the packet must go through, with the ssrr option,
+every next hop router must be specified.
+.PP
+The complete list of IPv4 options that can be matched on is:
+addext (Address Extention),
+cipso (Classical IP Security Option),
+dps (Dynamic Packet State),
+e-sec (Extended Security),
+eip (Extended Internet Protocol),
+encode (ENCODE),
+finn (Experimental Flow Control),
+imitd (IMI Traffic Descriptor),
+lsrr (Loose Source Route),
+mtup (MTU Probe - obsolete),
+mtur (MTU response - obsolete),
+nop (No Operation),
+nsapa (NSAP Address),
+rr (Record Route),
+rtralrt (Router Alert),
+satid (Stream Identifier),
+sdb (Selective Directed Broadcast),
+sec (Security),
+ssrr (Strict Source Route),
+tr (Tracerote),
+ts (Timestamp),
+ump (Upstream Multicast Packet),
+visa (Experimental Access Control)
+and zsu (Experimental Measurement).
+.SS Security with CIPSO and IPSO
+.PP
+IPFilter supports filtering on IPv4 packets using security attributes embedded
+in the IP options part of the packet. These options are usually only used on
+networks and systems that are using lablled security. Unless you know that
+you are using labelled security and your networking is also labelled, it
+is highly unlikely that this section will be relevant to you.
+.PP
+With the traditional IP Security Options (IPSO), packets can be tagged with
+a security level. The following keywords are recognised and match with the
+relevant RFC with respect to the bit patterns matched:
+confid (confidential),
+rserve-1 (1st reserved value),
+rserve-2 (2nd reserved value),
+rserve-3 (3rd reserved value),
+rserve-4 (4th reserved value),
+secret (secret),
+topsecret (top secret),
+unclass (unclassified).
+.PP
+.nf
+block in quick all with opt sec-class unclass
+pass in all with opt sec-class secret
+.fi
+.SS Matching IPv6 extension headers
+.PP
+Just as it is possible to filter on the various IPv4 header options,
+so too it is possible to filter on the IPv6 extension headers that are
+placed between the IPv6 header and the transport protocol header.
+.PP
+dstopts (destination options),
+esp (encrypted, secure, payload),
+frag (fragment),
+hopopts (hop-by-hop options),
+ipv6 (IPv6 header),
+mobility (IP mobility),
+none,
+routing.
+.SS Logging
+.PP
+There are two ways in which packets can be logged with IPFilter. The
+first is with a rule that specifically says log these types of packets
+and the second is a qualifier to one of the other keywords. Thus it is
+possible to both log and allow or deny a packet with a single rule.
+.PP
+.nf
+pass in log quick proto tcp from any to any port = 22
+.fi
+.PP
+When using stateful filtering, the log action becomes part of the result
+that is remembered about a packet. Thus if the above rule was qualified
+with keep state, every packet in the connection would be logged. To only
+log the first packet from every packet flow tracked with keep state, it
+is necessary to indicate to IPFilter that you only wish to log the first
+packet.
+.PP
+.nf
+pass in log first quick proto tcp from any to any port = 22 \\
+    flags S keep state
+.fi
+.PP
+If it is a requirement that the logging provide an accurate representation
+of which connections are allowed, the log action can be qualified with the
+option or-block. This allows the administrator to instruct IPFilter to
+block the packet if the attempt to record the packet in IPFilter's kernel
+log records (which have an upper bound on size) failed. Unless the system
+shuts down or reboots, once a log record is written into the kernel buffer,
+it is there until ipmon(8) reads it.
+.PP
+.nf
+block in log proto tcp from any to any port = smtp
+pass in log or-block first quick proto tcp from any \\
+    to any port = 22 flags S keep state
+.fi
+.PP
+By default, IPFilter will only log the header portion of a packet received
+on the network. A portion of the body of a packet, upto 128 bytes, can also
+be logged with the body keyword. ipmon(8) will display the contents of the
+portion of the body logged in hex.
+.PP
+.nf
+block in log body proto icmp all
+.fi
+.PP
+When logging packets from ipmon(8) to syslog, by default ipmon(8) will
+control what syslog facility and priority a packet will be logged with.
+This can be tuned on a per rule basis like this:
+.PP
+.nf
+block in quick log level err all with bad
+pass in log level local1.info proto tcp \\
+    from any to any port = 22 flags S keep state
+.fi
+.PP
+ipfstat(8) reports how many packets have been successfully logged and how
+many failed attempts to log a packet there were.
+.SS Filter rule comments
+.PP
+If there is a desire to associate a text string, be it an administrative
+comment or otherwise, with an IPFilter rule, this can be achieved by giving
+the filter rule a comment.  The comment is loaded with the rule into the
+kernel and can be seen when the rules are listed with ipfstat.
+.PP
+.nf
+pass in quick proto tcp from any \\
+    to port = 80 comment "all web server traffic is ok"
+pass out quick proto tcp from any port = 80 \\
+    to any comment "all web server traffic is ok"
+.fi
+.SS Tags
+.PP
+To enable filtering and NAT to correctly match up packets with rules,
+tags can be added at with NAT (for inbound packets) and filtering (for
+outbound packets.) This allows a filter to be correctly mated with its
+NAT rule in the event that the NAT rule changed the packet in a way
+that would mean it is not obvious what it was.
+.PP
+For inbound packets, IPFilter can match the tag used in the filter
+rules with that set by NAT. For outbound rules, it is the reverse,
+the filter sets the tag and the NAT rule matches up with it.
+.PP
+.nf
+pass in ... match-tag(nat=proxy)
+pass out ... set-tag(nat=proxy)
+.fi
+.PP
+Another use of tags is to supply a number that is only used with logging.
+When packets match these rules, the log tag is carried over into the
+log file records generated by ipmon(8). With the correct use of tools
+such as grep, extracting log records of interest is simplified.
+.PP
+.nf
+block in quick log ... set-tag(log=33)
+.fi
+.SH Filter Rule Expiration
+.PP
+IPFilter allows rules to be added into the kernel that it will remove after
+a specific period of time by specifying rule-ttl at the end of a rule.
+When listing rules in the kernel using ipfstat(8), rules that are going
+to expire will NOT display "rule-ttl" with the timeout, rather what will
+be seen is a comment with how many ipfilter ticks left the rule has to
+live.
+.PP
+The time to live is specified in seconds.
+.PP
+.nf

+.SH Internal packet attributes
+.PP
+In addition to being able to filter on very specific network and transport
+header fields, it is possible to filter on other attributes that IPFilter
+attaches to a packet. These attributes are placed in a rule after the
+keyword "with", as can be seen with frags and frag-body above. The
+following is a list of the other attributes available:
+.HP
+oow
+the packet's IP addresses and TCP ports match an existing entry in the
+state table but the sequence numbers indicate that it is outside of the
+accepted window.
+.IP
+.nf
+block return-rst in quick proto tcp from any to any with not oow
+.fi
+.HP
+bcast
+this is set by IPFilter when it receives notification that the link
+layer packet was a broadcast packet. No checking of the IP addresses
+is performned to determine if it is a broadcast destination or not.
+.IP
+.nf
+block in quick proto udp all with bcast
+.fi
+.HP
+mcast
+this is set by IPFilter when it receives notification that the link
+layer packet was a multicast packet. No checking of the IP addresses
+is performned to determine if it is a multicast destination or not.
+.IP
+.nf
+pass in quick proto udp from any to any port = dns with mcast
+.fi
+.HP
+mbcast
+can be used to match a packet that is either a multicast or broadcast
+packet at the link layer, as indicated by the operating system.
+.IP
+.nf
+pass in quick proto udp from any to any port = ntp with mbcast
+.fi
+.HP
+nat
+the packet positively matched a NAT table entry.
+.HP
+bad
+sanity checking of the packet failed. This could indicate that the
+layer 3/4 headers are not properly formed.
+.HP
+bad-src
+when reverse path verification is enabled, this flag will be set when
+the interface the packet is received on does not match that which would
+be used to send a packet out of to the source address in the received
+packet.
+.HP
+bad-nat
+an attempt to perform NAT on the packet failed.
+.HP
+not
+each one of the attributes matched using the "with" keyword can also be
+looked for to not be present. For example, to only allow in good packets,
+I can do this:
+.PP
+.nf
+block in all
+pass in all with not bad
+.fi
+.SH Tuning IPFilter
+.PP
+The ipf.conf file can also be used to tune the behaviour of IPFilter,
+allowing, for example, timeouts for the NAT/state table(s) to be set
+along with their sizes. The presence and names of tunables may change
+from one release of IPFilter to the next. The tunables that can be
+changed via ipf.conf is the same as those that can be seen and modified
+using the -T command line option to ipf(8).
+.PP
+NOTE: When parsing ipf.conf, ipf(8) will apply the settings before
+loading any rules. Thus if your settings are at the top, these may
+be applied whilst the rules not applied if there is an error further
+down in the configuration file.
+.PP
+To set one of the values below, the syntax is simple: "set", followed
+by the name of the tuneable to set and then the value to set it to.
+.PP
+.nf
+set state_max 9999;
+set state_size 10101;
+.fi
+.PP
+A list of the currently available variables inside IPFilter that may
+be tuned from ipf.conf are as follows:
+.HP
+active
+set through -s command line switch of ipf(8). See ipf(8) for detals.
+.HP
+chksrc
+when set, enables reverse path verification on source addresses and
+for filters to match packets with bad-src attribute.
+.HP
+control_forwarding
+when set turns off kernel forwarding when IPFilter is disabled or unloaded.
+.HP
+default_pass
+the default policy - whether packets are blocked or passed, etc - is
+represented by the value of this variable. It is a bit field and the
+bits that can be set are found in <netinet/ip_fil.h>. It is not
+recommended to tune this value directly.
+.HP
+ftp_debug
+set the debugging level of the in-kernel FTP proxy.
+Debug messages will be printed to the system console.
+.HP
+ftp_forcepasv
+when set the FTP proxy must see a PASV/EPSV command before creating
+the state/NAT entries for the 227 response.
+.HP
+ftp_insecure
+when set the FTP proxy will not wait for a user to login before allowing
+data connections to be created.
+.HP
+ftp_pasvonly
+when set the proxy will not create state/NAT entries for when it
+sees either the PORT or EPRT command.
+.HP
+ftp_pasvrdr
+when enabled causes the FTP proxy to create very insecure NAT/state
+entries that will allow any connection between the client and server
+hosts when a 227 reply is seen.  Use with extreme caution.
+.HP
+ftp_single_xfer
+when set the FTP proxy will only allow one data connection at a time.
+.HP
+hostmap_size
+sets the size of the hostmap table used by NAT to store address mappings
+for use with sticky rules.
+.HP
+icmp_ack_timeout
+default timeout used for ICMP NAT/state when a reply packet is seen for
+an ICMP state that already exists
+.HP

+.HP
+ip_timeout
+default timeout used for NAT/state entries that are not TCP/UDP/ICMP.
+.HP
+ipf_flags
+.HP
+ips_proxy_debug
+this sets the debugging level for the proxy support code.
+When enabled, debugging messages will be printed to the system console.
+.HP
+log_all
+when set it changes the behaviour of "log body" to log the entire packet
+rather than just the first 128 bytes.
+.HP
+log_size
+sets the size of the in-kernel log buffer in bytes.
+.HP
+log_suppress
+when set, IPFilter will check to see if the packet it is logging is
+similar to the one it previously logged and if so, increases
+the occurance count for that packet. The previously logged packet
+must not have yet been read by ipmon(8).
+.HP
+min_ttl
+is used to set the TTL value that packets below will be marked with
+the low-ttl attribute.
+.HP
+nat_doflush
+if set it will cause the NAT code to do a more aggressive flush of the
+NAT table at the next opportunity. Once the flush has been done, the
+value is reset to 0.

+.SH Calling out to internal functions
+.PP
+IPFilter provides a pair of functions that can be called from a rule
+that allow for a single rule to jump out to a group rather than walk
+through a list of rules to find the group. If you've got multiple
+networks, each with its own group of rules, this feature may help
+provide better filtering performance.
+.PP
+The lookup to find which rule group to jump to is done on either the
+source address or the destination address but not both.
+.PP
+In this example below, we are blocking all packets by default but then
+doing a lookup on the source address from group 1010. The two rules in
+the ipf.conf section are lone members of their group. For an incoming
+packet that is from 1.1.1.1, it will go through three rules: (1) the
+block rule, (2) the call rule and (3) the pass rule for group 1020.
+For a packet that is from 3.3.2.2, it will also go through three rules:
+(1) the block rule, (2) the call rule and (3) the pass rule for group
+1030. Should a packet from 3.1.1.1 arrive, it will be blocked as it
+does not match any of the entries in group 1010, leaving it to only
+match the first rule.
+.PP
+.nf
+from ipf.conf
+-------------
+block in all
+call now srcgrpmap/1010 in all
+pass in proto tcp from any to any port = 80 group 1020
+pass in proto icmp all icmp-type echo group 1030
 
-and to then allow ICMP packets in on le0, only, we would do:
-.LP
+from ippool.conf
+----------------
+group-map in role=ipf number=1010
+    { 1.1.1.1 group = 1020, 3.3.0.0/16 group = 1030; };
+.fi
+.SS IPFilter matching expressions
+.PP
+An experimental feature that has been added to filter rules is to use
+the same expression matching that is available with various commands
+to flush and list state/NAT table entries. The use of such an expression
+precludes the filter rule from using the normal IP header matching.
+.PP
 .nf
-       pass in proto icmp all group 100
+pass in exp { "tcp.sport 23 or tcp.sport 50" } keep state
 .fi
+.SS Filter rules with BPF
+.PP
+On platforms that have the BPF built into the kernel, IPFilter can be
+built to allow BPF expressions in filter rules. This allows for packet
+matching to be on arbitrary data in the packt. The use of a BPF expression
+replaces all of the other protocol header matching done by IPFilter.
 .PP
-Note that because only inbound packets on le0 are used processed by group 100,
-there is no need to respecify the interface name.  Likewise, we could further
-breakup processing of TCP, etc, as follows:
-.LP
 .nf
-       block in proto tcp all head 110 group 100
-       pass in from any to any port = 23 group 110
+pass in bpf-v4 { "tcp and (src port 23 or src port 50)" } \\
+    keep state
 .fi
 .PP
-and so on.  The last line, if written without the groups would be:
-.LP
+These rules tend to be
+write-only because the act of compiling the filter expression into the
+BPF instructions loaded into the kernel can make it difficut to
+accurately reconstruct the original text filter. The end result is that
+while ipf.conf() can be easy to read, understanding the output from
+ipfstat might not be.
+.SH VARIABLES
+.PP
+This configuration file, like all others used with IPFilter, supports the
+use of variable substitution throughout the text.
+.PP
+.nf
+nif="ppp0";
+pass in on $nif from any to any
+.fi
+.PP
+would become
+.PP
 .nf
-       pass in on le0 proto tcp from any to any port = telnet
+pass in on ppp0 from any to any
 .fi
 .PP
-Note, that if we wanted to say "port = telnet", "proto tcp" would
-need to be specified as the parser interprets each rule on its own and
-qualifies all service/port names with the protocol specified.
+Variables can be used recursively, such as 'foo="$bar baz";', so long as
+$bar exists when the parser reaches the assignment for foo.

-.SH OVERVIEW
+and is roughly described like this:
+.PP
+match { \fImatch-it ,match-it, ...\fP } do { \fIaction, action, ...\fP};
 .PP
-The ipmon configuration file is used for defining rules to be executed when
-logging records are read from
-.B /dev/ipl.
+where there can be a list of matching expressions and a list of actions
+to perform if all of the matching expressions are matched up with by
+the current log entry.
 .PP
+The lines above would save all ipf log entries to /var/log/ipf-log, send
+all of the entries for NAT (ipnat related) to syslog and generate an email
+to root for each log entry from the state tables.
+.SH SYNTAX - MATCHING
+.PP
+In the above example, the matching segment was confined to matching on
+the type of log entry generated.  The full list of fields that can be
+used here is:
+.TP
+direction <in|out>
+This option is used to match on log records generated for packets going
+in or out.
+.TP
+dstip <address/mask>
+This option is used to match against the destination address associated
+with the packet being logged.  A "/mask" must be given and given in CIDR
+notation (/0-/32) so to specify host 192.2.2.1, 192.2.2.1/32 must be given.
+.TP
+dstport <portnumber>
+This option is used to match against the destination port in log entries.
+A number must be given, symbolic names (such as those from /etc/services)
+are not recognised by the parser.
+.TP
+every <second|# seconds|packet|# packets>
+This option is used to regulate how often an \fBipmon.conf\fR entry is
+actioned in response to an otherwise matching log record from the kernel.
+.TP
+group <name|number>
+.TP
+interface <interface-name>
+This option is used to match against the network interface name associated
+with the action causing the logging to happen.  In general this will be the
+network interface where the packet is seen by IPFilter.
+.TP
+logtag <number>
+This option is used to match against tags set by ipf rules in \fBipf.conf\fR.
+These tags are set with "set-tag(log=100)" appended to filter rules.
+.TP
+nattag <string>
+This option is used to match against tags set by NAT rules in \fBipnat.conf\fR.
+.TP
+protocol <name|number>
+This option is used to match against the IP protocol field in the packet
+being logged.
+.TP
+result <pass|block|nomatch|log>
+This option is used to match against the result of packet matching in the
+kernel.  If a packet is logged, using a \fBlog\fR rule in \fBipf.conf\fR
+then it will match "log" here.  The "nomatch" option is for use with
+matching log records generated for all packets as the default.
+.TP
+rule <number>
+This option is used to match against the \fInumber\fR of the rule
+causing the record to be generated.  The \fInumber\fR of a rule can be
+observed using "ipfstat -ion".
+.TP
+srcip <address/mask>
+This option is used to match against the source address associated
+with the packet being logged.  A "/mask" must be given and given in CIDR
+notation (/0-/32) so to specify host 192.2.2.1, 192.2.2.1/32 must be given.
+.TP
+srcport <portnumber>
+This option is used to match against the source port in log entries.
+A number must be given, symbolic names (such as those from /etc/services)
+are not recognised by the parser.
+.TP
+type <ipf|nat|state>
+The format for files accepted by ipmon is described by the following grammar:
+.B NOTE:
 At present, only IPv4 matching is available for source/destination address
 matching.
+.SH SYNTAX - ACTIONS
+The list of actions supported is as follows:
+.TP
+save("file://<filename>")
+save("raw://<filename>")
+Write out the log record to the filename given.  This file will be closed
+and reopened on receipt of a SIGHUP.  If the \fIraw\fP target is used,
+binary log data, as read from the kernel, is written out rather than a
+text log record. The filename should be an absolute target, including
+the root directory. Thus, saving to /var/log/ipmon.log would be, as an
+example, save("file:///var/log/ipmon.log").
+.TP
+syslog("<facility>.<priority>")
+syslog("<facility>.")
+syslog(".<priority>")
+To log a text record via syslog, the \fBsyslog\fP action word is used.
+The facility used by default is determined at first by the default
+compiled into \fBipmon\fP (usually LOG_LOCAL0), which can be changed
+via the command line (-L <facility>) or in an \fBipf.conf\fP rule
+using the \fIlevel\fP option with logging.  If the facility is
+specified here, it takes precedence over all other settings.
+The same applies to the syslog priority. By default, ipmon will
+determine a priority for the packet, depending on whether or not it
+has been blocked, passed, etc. It is possible to force the complete
+facility/priority value for each log entry or to choose to replace
+only one of them.
+.TP
+execute("<command string>")
+The
+.B execute
+action runs the specified command each time the log entry matches
+and feeds the log entry, as text, to the command being executed.
+The command string given is executed using /bin/sh.
+.TP
+nothing
+Literally, do nothing.  Use this if you want to be verbose in your config
+file about doing nothing for a particular log record.
+.SH PLUGIN ACTIONS
+It is possible to configure
+.B ipmon
+to use externally supplied modules to save log entries with.
+These are added to
+.B ipmon
+using the
+.I load_action
+configuration line. The syntax of this line is:
+.nf
+
+load_action <name> <path>;
+.fi
+.TP
+name
+is a short name for the action. It does not need to correspond to the
+name of the library file, but inside the library file, the functions
+.B <name>destroy
+,
+.B <name>parse
+and
+.B <name>store
+must be present.
+.TP
+path
+specifies the path in the filesystem to the shared object
+that contains the implementation of the new action. After the new
+action has been declared using
+.I load_action
+it can then be used in any
+.I do
+statement.
+.SH EXAMPLES
+.PP
+Some further examples are:
+.nf
+
+#
+# log everything to syslog local4, regardless
+#
+match { ; } do { syslog("local4."); };
+#
+# keep a local copy of things packets to/from port 80
+#
+match { srcport = 80; } do { save("file:///var/log/web"); };
+match { dstport = 80; } do { save("file:///var/log/web"); };
+#
+load_action local "/usr/lib/libmyaction.so";
+match { dstip 127.0.0.1; } do { local("local options"); };
+#

+.PP
+The
+.B ipnat.conf
+file is used to specify rules for the Network Address Translation (NAT)
+component of IPFilter.  To load rules specified in the
+.B ipnat.conf
+file, the
+.B ipnat(8)
+program is used.
 .PP
 For standard NAT functionality, a rule should start with \fBmap\fP and then
 proceeds to specify the interface for which outgoing packets will have their
-source address rewritten.
-.PP
-Packets which will be rewritten can only be selected by matching the original
-source address.  A netmask must be specified with the IP address.
-.PP
-The address selected for replacing the original is chosen from an IP#/netmask
-pair.  A netmask of all 1's indicating a hostname is valid.  A netmask of
-31 1's (255.255.255.254) is considered invalid as there is no space for
-allocating host IP#'s after consideration for broadcast and network
-addresses.
-.PP
-When remapping TCP and UDP packets, it is also possible to change the source
-port number.  Either TCP or UDP or both can be selected by each rule, with a
-range of port numbers to remap into given as \fBport-number:port-number\fP.
-.SH COMMANDS
-There are four commands recognised by IP Filter's NAT code:
-.TP
+source address rewritten.  Following this it is expected that the old source
+address, and optionally port number, will be specified.
+.PP
+In general, all NAT rules conform to the following layout:
+the first word indicates what type of NAT rule is present, this is followed
+by some stanzas to match a packet, followed by a "->" and this is then
+followed by several more stanzas describing the new data to be put in the
+packet.
+.PP
+In this text and in others,
+use of the term "left hand side" (LHS) when talking about a NAT rule refers
+to text that appears before the "->" and the "right hand side" (RHS) for text
+that appears after it.  In essence, the LHS is the packet matching and the
+RHS is the new data to be used.
+.SH VARIABLES
+.PP
+This configuration file, like all others used with IPFilter, supports the
+use of variable substitution throughout the text.
+.nf
+
+nif="ppp0";
+map $nif 0/0 -> 0/32
+.fi
+.PP
+would become
+.nf
+
+map ppp0 0/0 -> 0/32
+.fi
+.PP
+Variables can be used recursively, such as 'foo="$bar baz";', so long as
+$bar exists when the parser reaches the assignment for foo.
+.PP
+See
+.B ipnat(8)
+for instructions on how to define variables to be used from a shell
+environment.
+.SH OUTBOUND SOURCE TRANSLATION (map'ing)
+Changing the source address of a packet is traditionally performed using
 .B map
-that is used for mapping one address or network to another in an unregulated
-round robin fashion;
-.TP
-.B rdr
-that is used for redirecting packets to one IP address and port pair to
-another;
-.TP
-.B bimap
-for setting up bidirectional NAT between an external IP address and an internal
-IP address and
+rules.  Both the source address and optionally port number can be changed
+according to various controls.
+.PP
+To start out with, a common rule used is of the form:
+.nf
+
+map le0 0/0 -> 0/32
+.fi
+.PP
+Here we're saying change the source address of all packets going out of
+le0 (the address/mask pair of 0/0 matching all packets) to that of the
+interface le0 (0/32 is a synonym for the interface's own address at
+the current point in time.)  If we wanted to pass the packet through
+with no change in address, we would write it as:
+.nf
+
+map le0 0/0 -> 0/0
+.fi
+.PP
+If we only want to change a portion of our internal network and to a
+different address that is routed back through this host, we might do:
+.nf
+
+map le0 10.1.1.0/24 -> 192.168.55.3/32
+.fi
+.PP
+In some instances, we may have an entire subnet to map internal addresses
+out onto, in which case we can express the translation as this:
+.nf
+
+map le0 10.0.0.0/8 -> 192.168.55.0/24
+.fi
+.PP
+IPFilter will cycle through each of the 256 addresses in the 192.168.55.0/24
+address space to ensure that they all get used.
+.PP
+Of course this poses a problem for TCP and UDP, with many connections made,
+each with its own port number pair.  If we're unlucky, translations can be
+dropped because the new address/port pair mapping already exists.  To
+mitigate this problem, we add in port translation or port mapping:
+.nf
+
+map le0 10.0.0.0/8 -> 192.168.55.0/24 portmap tcp/udp auto
+.fi
+.PP
+In this instance, the word "auto" tells IPFilter to calculate a private
+range of port numbers for each address on the LHS to use without fear
+of them being trampled by others.  This can lead to problems if there are
+connections being generated mire quickly than IPFilter can expire them.
+In this instance, and if we want to get away from a private range of
+port numbers, we can say:
+.nf
+
+map le0 10.0.0.0/8 -> 192.168.55.0/24 portmap tcp/udp 5000:65000
+.fi
+.PP
+And now each connection through le0 will add to the enumeration of
+the port number space 5000-65000 as well as the IP address subnet
+of 192.168.55.0/24.
+.PP
+If the new addresses to be used are in a consecutive range, rather
+than a complete subnet, we can express this as:
+.nf
+
+map le0 10.0.0.0/8 -> range 192.168.55.10-192.168.55.249
+                      portmap tcp/udp 5000:65000
+.fi
+.PP
+This tells IPFilter that it has a range of 240 IP address to use, from
+192.168.55.10 to 192.168.55.249, inclusive.
+.PP
+If there were several ranges of addresses for use, we can use each one
+in a round-robin fashion as followed:
+.nf
+
+map le0 10.0.0.0/8 -> range 192.168.55.10-192.168.55.29
+                      portmap tcp/udp 5000:65000 round-robin
+map le0 10.0.0.0/8 -> range 192.168.55.40-192.168.55.49
+                      portmap tcp/udp 5000:65000 round-robin
+.fi
+.PP
+To specify translation rules that impact a specific IP protocol,
+the protocol name or number is appended to the rule like this:
+.nf
+
+map le0 10.0.0.0/8 -> 192.168.55.0/24 tcp/udp
+map le0 10.0.0.0/8 -> 192.168.55.1/32 icmp
+map le0 10.0.0.0/8 -> 192.168.55.2/32 gre
+.fi
+.PP
+For TCP connections exiting a connection such as PPPoE where the MTU is
+slightly smaller than normal ethernet, it can be useful to reduce the
+Maximum Segment Size (MSS) offered by the internal machines to match,
+reducing the liklihood that the either end will attempt to send packets
+that are too big and result in fragmentation.  This is acheived using the
+.B mssclamp
+option with TCP
+.B map
+rules like this:
+.nf
+
+map pppoe0 0/0 -> 0/32 mssclamp 1400 tcp
+.fi
+.PP
+For ICMP packets, we can map the ICMP id space in query packets:
+.nf
+
+map le0 10.0.0.0/8 -> 192.168.55.1/32 icmpidmap icmp 1000:20000
+.fi
+.PP
+If we wish to be more specific about our initial matching criteria on the
+LHS, we can expand to using a syntax more similar to that in
+.B ipf.conf(5)
+:
+.nf
+
+map le0 from 10.0.0.0/8 to 26.0.0.0/8 ->
+                      192.168.55.1
+map le0 from 10.0.0.0/8 port > 1024 to 26.0.0.0/8 ->
+                      192.168.55.2 portmap 5000:9999 tcp/udp
+map le0 from 10.0.0.0/8 ! to 26.0.0.0/8 ->
+                      192.168.55.3 portmap 5000:9999 tcp/udp
+.fi

 .B map-block
-which sets up static IP address based translation, based on a algorithm to
-squeeze the addresses to be translated into the destination range.
-.SH MATCHING
-.PP
-For basic NAT and redirection of packets, the address subject to change is used
-along with its protocol to check if a packet should be altered.  The packet
-\fImatching\fP part of the rule is to the left of the "->" in each rule.
-.PP
-Matching of packets has now been extended to allow more complex compares.
-In place of the address which is to be translated, an IP address and port
-number comparison can be made using the same expressions available with
-\fBipf\fP.  A simple NAT rule could be written as:
+rules.
+.PP
+The NAT code has builtin default timeouts for TCP, UDP, ICMP and another
+for all other protocols.  In general, the timeout for an entry to be
+deleted shrinks once a reply packet has been seen (excluding TCP.)
+If you wish to specify your own timeouts, this can be achieved either
+by setting one timeout for both directions:
+.nf
+
+map le0 0/0 -> 0/32 gre age 30
+.fi
+.PP
+or setting a different timeout for the reply:
+.nf
+
+map le0 from any to any port = 53 -> 0/32 age 60/10 udp
+.fi
+.PP
+A pressing problem that many people encounter when using NAT is that the
+address protocol can be embedded inside an application's communication.
+To address this problem, IPFilter provides a number of built-in proxies
+for the more common trouble makers, such as FTP.  These proxies can be
+used as follows:
+.nf
+
+map le0 0/0 -> 0/32 proxy port 21 ftp/tcp
+.fi
+.PP
+In this rule, the word "proxy" tells us that we want to connect up this
+translation with an internal proxy.  The "port 21" is an extra restriction
+that requires the destination port number to be 21 if this rule is to be
+activated.  The word "ftp" is the proxy identifier that the kernel will
+try and resolve internally, "tcp" the protocol that packets must match.
+.PP
+See below for a list of proxies and their relative staus.
+.PP
+To associate NAT rules with filtering rules, it is possible to set and
+match tags during either inbound or outbound processing.  At present the
+tags for forwarded packets are not preserved by forwarding, so once the
+packet leaves IPFilter, the tag is forgotten.  For
+.B map
+rules, we can match tags set by filter rules like this:
+.nf
+
+map le0 0/0 -> 0/32 proxy portmap 5000:5999 tag lan1 tcp
+.fi
+.PP
+This would be used with "pass out" rules that includes a stanza such
+as "set-tag (nat = lan1)".
+.PP
+If the interface in which packets are received is different from the
+interface on which packets are sent out, then the translation rule needs
+to be written to take this into account:
+.nf
+
+map hme0,le0 0/0 -> 0/32
+.fi
+.PP
+Although this might seem counterintuitive, the interfaces when listed
+in rules for
+.B ipnat.conf
+are always in the
+.I inbound
+,
+.I outbound
+order.  In this case, hme0 would be the return interface and le0 would be
+the outgoing interface.  If you wish to allow return packets on any
+interface, the correct syntax to use would be:
+.nf
+
+map *,le0 0/0 -> 0/32
+.fi
 .LP
+A special variant of
+.B map
+rules exists, called
+.B map-block.
+This command is intended for use when there is a large network to be mapped
+onto a smaller network, where the difference in netmasks is upto 14 bits
+difference in size.  This is achieved by dividing the address space and
+port space up to ensure that each source address has its own private range
+of ports to use.  For example, this rule:
+.nf
+
+map-block ppp0 172.192.0.0/16 -> 209.1.2.0/24 ports auto
+.fi
+.PP
+would result in 172.192.0.0/24 being mapped to 209.1.2.0/32
+with each address, from 172.192.0.0 to 172.192.0.255 having 252 ports of its
+own.  As opposed to the above use of \fBmap\fP, if for some reason the user
+of (say) 172.192.0.2 wanted 260 simultaneous connections going out, they would
+be limited to 252 with \fBmap-block\fP but would just \fImove on\fP to the next
+IP address with the \fBmap\fP command.
+.SS Extended matching
+.PP
+If it is desirable to match on both the source and destination of a packet
+before applying an address translation to it, this can be achieved by using
+the same from-to syntax as is used in \fBipf.conf\fP(5).  What follows
+applies equally to the
+.B map
+rules discussed above and
+.B rdr
+rules discussed below.  A simple example is as follows:
+.nf
+
+map bge0 from 10.1.0.0/16 to 192.168.1.0/24 -> 172.12.1.4
+.fi
+.PP
+This would only match packets that are coming from hosts that have a source
+address matching 10.1.0.0/16 and a destination matching 192.168.1.0/24.
+This can be expanded upon with ports for TCP like this:
+.nf
+
+rdr bge0 from 10.1.0.0/16 to any port = 25 -> 127.0.0.1 port 2501 tcp
+.fi
+.PP
+Where only TCP packets from 10.1.0.0/16 to port 25 will be redirected to
+port 2501.
+.PP
+As with \fBipf.conf\fR(5), if we have a large set of networks or addresses
+that we would like to match up with then we can define a pool using
+\fBippool\fR(8) in \fBippool.conf\fR(5) and then refer to it in an
+\fBipnat\fR rule like this:
+.nf
+
+map bge0 from pool/100 to any port = 25 -> 127.0.0.1 port 2501 tcp
+.fi
+.TP
+.B NOTE:
+In this situation, the rule is considered to have a netmask of "0" and
+thus is looked at last, after any rules with /16's or /24's in them,
+.I even if
+the defined pool only has /24's or /32's.  Pools may also be used
+.I wherever
+the from-to syntax in \fBipnat.conf\fR(5) is allowed.
+.SH INBOUND DESTINATION TRANSLATION (redirection)
+.PP
+Redirection of packets is used to change the destination fields in a packet
+and is supported for packets that are moving \fIin\fP on a network interface.
+While the same general syntax for
+.B map
+rules is supported, there are differences and limitations.
+.PP
+Firstly, by default all redirection rules target a single IP address, not
+a network or range of network addresses, so a rule written like this:
+.nf
+
+rdr le0 0/0 -> 192.168.1.0
+.fi
+.PP
+Will not spread packets across all 256 IP addresses in that class C network.
+If you were to try a rule like this:
+.nf
+
+rdr le0 0/0 -> 192.168.1.0/24
+.fi
+.PP
+then you will receive a parsing error.
+.PP
+The from-to source-destination matching used with
+.B map
+rules can be used with rdr rules, along with negation, however the
+restriction moves - only a source address match can be negated:
+.nf
+
+rdr le0 from 1.1.0.0/16 to any -> 192.168.1.3
+rdr le0 ! from 1.1.0.0/16 to any -> 192.168.1.4
+.fi
+.PP
+If there is a consective set of addresses you wish to spread the packets
+over, then this can be done in one of two ways, the word "range" optional
+to preserve:
+.nf
+
+rdr le0 0/0 -> 192.168.1.1 - 192.168.1.5
+rdr le0 0/0 -> range 192.168.1.1 - 192.168.1.5
+.fi
+.PP
+If there are only two addresses to split the packets across, the
+recommended method is to use a comma (",") like this:
+.nf
+
+rdr le0 0/0 -> 192.168.1.1,192.168.1.2
+.fi
+.PP
+If there is a large group of destination addresses that are somewhat
+disjoint in nature, we can cycle through them using a
+.B round-robin
+technique like this:
 .nf
-map de0 10.1.0.0/16 -> 201.2.3.4/32
+
+rdr le0 0/0 -> 192.168.1.1,192.168.1.2 round-robin
+rdr le0 0/0 -> 192.168.1.5,192.168.1.7 round-robin
+rdr le0 0/0 -> 192.168.1.9 round-robin
+.fi
+.PP
+If there are a large number of redirect rules and hosts being targetted
+then it may be desirable to have all those from a single source address
+be targetted at the same destination address.  To achieve this, the
+word
+.B sticky
+is appended to the rule like this:
+.nf
+
+rdr le0 0/0 -> 192.168.1.1,192.168.1.2 sticky
+rdr le0 0/0 -> 192.168.1.5,192.168.1.7 round-robin sticky
+rdr le0 0/0 -> 192.168.1.9 round-robin sticky
+.fi
+.PP
+The
+.B sticky
+feature can only be combined with
+.B round-robin
+and the use of comma.
+.PP
+For TCP and UDP packets, it is possible to both match on the destiantion
+port number and to modify it.  For example, to change the destination port
+from 80 to 3128, we would use a rule like this:
+.nf
+
+rdr de0 0/0 port 80 -> 127.0.0.1 port 3128 tcp
+.fi
+.PP
+If a range of ports is given on the LHS and a single port is given on the
+RHS, the entire range of ports is moved.  For example, if we had this:
+.nf
+
+rdr le0 0/0 port 80-88 -> 127.0.0.1 port 3128 tcp
+.fi
+.PP
+then port 80 would become 3128, port 81 would become 3129, etc.  If we
+want to redirect a number of different pots to just a single port, an
+equals sign ("=") is placed before the port number on the RHS like this:
+.nf
+
+rdr le0 0/0 port 80-88 -> 127.0.0.1 port = 3128 tcp
+.fi
+.PP
+In this case, port 80 goes to 3128, port 81 to 3128, etc.
+.PP
+As with
+.B map
+rules, it is possible to manually set a timeout using the
+.B age
+option, like this:
+.nf
+
+rdr le0 0/0 port 53 -> 127.0.0.1 port 10053 udp age 5/5
+.fi
+.PP
+The use of proxies is not restricted to
+.B map
+rules and outbound sessions.  Proxies can also be used with redirect
+rules, although the syntax is slightly different:
+.nf
+
+rdr ge0 0/0 port 21 -> 127.0.0.1 port 21 tcp proxy ftp
+.fi
+.PP
+For
+.B rdr
+rules, the interfaces supplied are in the same order as
+.B map
+rules - input first, then output.  In situations where the outgoing interface
+is not certain, it is also possible to use a wildcard ("*") to effect a match
+on any interface.
+.nf
+
+rdr le0,* 0/0 -> 192.168.1.0
+.fi
+.PP
+A single rule, with as many options set as possible would look something like
+this:
+.nf
+
+rdr le0,ppp0 9.8.7.6/32 port 80 -> 1.1.1.1,1.1.1.2 port 80 tcp
+    round-robin frag age 40/40 sticky mssclamp 1000 tag tagged
 .fi
+.SH REWRITING SOURCE AND DESTINATION
+.PP
+Whilst the above two commands provide a lot of flexibility in changing
+addressing fields in packets, often it can be of benefit to translate
+\fIboth\fP source \fBand\fR destination at the same time or to change
+the source address on input or the destination address on output.
+Doing all of these things can be accomplished using
+.B rewrite
+NAT rules.
+.PP
+A
+.B rewrite
+rule requires the same level of packet matching as before, protocol and
+source/destination information but in addition allows either
+.B in
+or
+.B out
+to be specified like this:
+.nf
+
+rewrite in on ppp0 proto tcp from any to any port = 80 ->
+	src 0/0 dst 127.0.0.1,3128;
+rewrite out on ppp0 from any to any ->
+	src 0/32 dst 10.1.1.0/24;
+.fi
+.PP
+On the RHS we can specify both new source and destination information to place
+into the packet being sent out.  As with other rules used in
+\fBipnat.conf\fR, there are shortcuts syntaxes available to use the original
+address information (\fB0/0\fR) and the address associated with the network
+interface (\fB0/32\fR.)  For TCP and UDP, both address and port information
+can be changed.  At present it is only possible to specify either a range of
+port numbers to be used (\fBX-Y\fR) or a single port number (\fB= X\fR) as
+follows:
+.nf
+
+rewrite in on le0 proto tcp from any to any port = 80 ->
+	src 0/0,2000-20000 dst 127.0.0.1,port = 3128;
+.fi
+.PP
+There are four fields that are stepped through in enumerating the number
+space available for creating a new destination:
+.LP
+source address
+.LP
+source port
 .LP
-or as
+destination address
 .LP
+destination port
+.PP
+If one of these happens to be a static then it will be skipped and the next
+one incremented.  As an example:
 .nf
-map de0 from 10.1.0.0/16 to any -> 201.2.3.4/32
+
+rewrite out on le0 proto tcp from any to any port = 80 ->
+	src 1.0.0.0/8,5000-5999 dst 2.0.0.0/24,6000-6999;
 .fi
+.PP
+The translated packets would be:
+.LP
+1st src=1.0.0.1,5000 dst=2.0.0.1,6000
+.LP
+2nd src=1.0.0.2,5000 dst=2.0.0.1,6000
+.LP
+3rd src=1.0.0.2,5001 dst=2.0.0.1,6000
 .LP
-Only IP address and port numbers can be compared against.  This is available
-with all NAT rules.
-.SH TRANSLATION
-.PP
-To the right of the "->" is the address and port specification which will be
-written into the packet providing it has already successfully matched the
-prior constraints.  The case of redirections (\fBrdr\fP) is the simplest:
-the new destination address is that specified in the rule.  For \fBmap\fP
-rules, the destination address will be one for which the tuple combining
-the new source and destination is known to be unique.  If the packet is
-either a TCP or UDP packet, the destination and source ports come into the
-equation too.  If the tuple already exists, IP Filter will increment the
-port number first, within the available range specified with \fBportmap\fP
-and if there exists no unique tuple, the source address will be incremented
-within the specified netmask.  If a unique tuple cannot be determined, then
-the packet will not be translated.  The \fBmap-block\fP is more limited in
-how it searches for a new, free and unique tuple, in that it will used an
-algorithm to determine what the new source address should be, along with the
-range of available ports - the IP address is never changed and nor does the
-port number ever exceed its allotted range.
-.SH ICMPIDMAP
-.PP
-ICMP messages can be divided into two groups: "errors" and "queries". ICMP
-errors are generated as a response of another IP packet. IP Filter will take
-care that ICMP errors that are the response of a NAT-ed IP packet are
-handled properly.
-.PP
-For 4 types of ICMP queries (echo request, timestamp request, information 
-request and address mask request) IP Filter supports an additional mapping
-called "ICMP id mapping". All these 4 types of ICMP queries use a unique
-identifier called the ICMP id. This id is set by the process sending the
-ICMP query and it is usually equal to the process id. The receiver of the
-ICMP query will use the same id in its response, thus enabling the
-sender to recognize that the incoming ICMP reply is intended for him and is
-an answer to a query that he made. The "ICMP id mapping" feature modifies 
-these ICMP id in a way identical to \fBportmap\fP for TCP or UDP.
-.PP
-The reason that you might want this, is that using this feature you don't
-need an IP address per host behind the NAT box, that wants to do ICMP queries.
-The two numbers behind the \fBicmpidmap\fP keyword are the first and the
-last icmp id number that can be used. There is one important caveat: if you
-map to an IP address that belongs to the NAT box itself (notably if you have
-only a single public IP address), then you must ensure that the NAT box does
-not use the \fBicmpidmap\fP range that you specified in the \fBmap\fP rule.
-Since the ICMP id is usually the process id, it is wise to restrict the
-largest permittable process id (PID) on your operating system to e.g. 63999 and
-use the range 64000:65535 for ICMP id mapping. Changing the maximal PID is
-system dependent. For most BSD derived systems can be done by changing 
-PID_MAX in /usr/include/sys/proc.h and then rebuild the system.
+4th src=1.0.0.2,5001 dst=2.0.0.2,6000

+.LP
+6th src=1.0.0.3,5001 dst=2.0.0.2,6001
+.PP
+and so on.
+.PP
+As with
+.B map
+rules, it is possible to specify a range of addresses by including the word
+\fIrange\fR before the addresses:
+.nf
+
+rewrite from any to any port = 80 ->
+	src 1.1.2.3 - 1.1.2.6 dst 2.2.3.4 - 2.2.3.6;
+.fi
+.SH DIVERTING PACKETS
+.PP
+If you'd like to send packets to a UDP socket rather than just another
+computer to be decapsulated, this can be achieved using a
+.B divert
+rule.
+.PP
+Divert rules can be be used with both inbound and outbound packet
+matching however the rule
+.B must
+specify host addresses for the outer packet, not ranges of addresses
+or netmasks, just single addresses.
+Additionally the syntax must supply required information for UDP.
+An example of what a divert rule looks ike is as follows:
+.nf
+
+divert in on le0 proto udp from any to any port = 53 ->
+	src 192.1.1.1,54 dst 192.168.1.22.1,5300;
+.fi
+.PP
+On the LHS is a normal set of matching capabilities but on the RHS it is
+a requirement to specify both the source and destination addresses and
+ports.
+.PP
+As this feature is intended to be used with targetting packets at sockets
+and not IPFilter running on other systems, there is no rule provided to
+\fIundivert\fR packets.
+.TP
+.B NOTE:
+Diverted packets \fImay\fP be fragmented if the addition of the
+encapsulating IP header plus UDP header causes the packet to exceed
+the size allowed by the outbound network interface.  At present it is
+not possible to cause Path MTU discovery to happen as this feature
+is intended to be transparent to both endpoints.
+.B Path MTU Discovery
+If Path MTU discovery is being used and the "do not fragment" flag
+is set in packets to be encapsulated, an ICMP error message will
+be sent back to the sender if the new packet would need to be
+fragmented.
+.SH COMMON OPTIONS
+This section deals with options that are available with all rules.
+.TP
+.B purge
+When the purge keyword is added to the end of a NAT rule, it will
+cause all of the active NAT sessions to be removed when the rule
+is removed as an individual operation. If all of the NAT rules
+are flushed out, it is expected that the operator will similarly
+flush the NAT table and thus NAT sessions are not removed when the
+NAT rules are flushed out.
+.SH RULE ORDERING
+.PP
+.B NOTE:
+Rules in
+.B ipnat.conf
+are read in sequentially as listed and loaded into the kernel in this
+fashion
+.B BUT
+packet matching is done on \fBnetmask\fR, going from 32 down to 0.
+If a rule uses
+.B pool
+or
+.B hash
+to reference a set of addresses or networks, the netmask value for
+these fields is considered to be "0".
+So if your
+.B ipnat.conf
+has the following rules:
+.nf
+
+rdr le0 192.0.0.0/8 port 80 -> 127.0.0.1 3132 tcp
+rdr le0 192.2.0.0/16 port 80 -> 127.0.0.1 3131 tcp
+rdr le0 from any to pool/100 port 80 -> 127.0.0.1 port 3130 tcp
+rdr le0 192.2.2.0/24 port 80 -> 127.0.0.1 3129 tcp
+rdr le0 192.2.2.1 port 80 -> 127.0.0.1 3128 tcp
+.fi
+.PP
+then the rule with 192.2.2.1 will match \fBfirst\fR, regardless of where
+it appears in the ordering of the above rules.  In fact, the order in
+which they would be used to match a packet is:
+.nf
+
+rdr le0 192.2.2.1 port 80 -> 127.0.0.1 3128 tcp
+rdr le0 192.2.2.0/24 port 80 -> 127.0.0.1 3129 tcp
+rdr le0 192.2.0.0/16 port 80 -> 127.0.0.1 3131 tcp
+rdr le0 192.0.0.0/8 port 80 -> 127.0.0.1 3132 tcp
+rdr le0 from any to pool/100 port 80 -> 127.0.0.1 port 3130 tcp
+.fi
+.PP
+where the first line is actually a /32.
+.PP
+If your
+.B ipnat.conf
+file has entries with matching target fields (source address for
+.B map
+rules and destination address for
+.B rdr
+rules), then the ordering in the
+.B ipnat.conf
+file does matter.  So if you had the following:
+.nf
+
+rdr le0 from 1.1.0.0/16 to 192.2.2.1 port 80 -> 127.0.0.1 3129 tcp
+rdr le0 from 1.1.1.0/24 to 192.2.2.1 port 80 -> 127.0.0.1 3128 tcp
+.fi
+.PP
+Then no packets will match the 2nd rule, they'll all match the first.
+.SH IPv6
+.PP
+In all of the examples above, where an IPv4 address is present, an IPv6
+address can also be used. All rules must use either IPv4 addresses with
+both halves of the NAT rule or IPv6 addresses for both halves. Mixing
+IPv6 addresses with IPv4 addresses, in a single rule, will result in an
+error.
+.PP
+For shorthand notations such as "0/32", the equivalent for IPv6 is
+"0/128". IPFilter will treat any netmask greater than 32 as an
+implicit direction that the address should be IPv6, not IPv4.
+To be unambiguous with 0/0, for IPv6 use ::0/0.

-the rule is removed from the top of the list and added to the end,
-automatically, as required.  This will not effect the display of rules
-using "ipnat -l", only the internal application order.
-.SH EXAMPLES
-.PP
-This section deals with the \fBmap\fP command and its variations.
-.PP
-To change IP#'s used internally from network 10 into an ISP provided 8 bit
-subnet at 209.1.2.0 through the ppp0 interface, the following would be used:
-.LP
-.nf
-map ppp0 10.0.0.0/8 -> 209.1.2.0/24
-.fi
-.PP
-The obvious problem here is we're trying to squeeze over 16,000,000 IP
-addresses into a 254 address space.  To increase the scope, remapping for TCP
-and/or UDP, port remapping can be used;
-.LP
-.nf
-map ppp0 10.0.0.0/8 -> 209.1.2.0/24 portmap tcp/udp 1025:65000
-.fi
-.PP
-which falls only 527,566 `addresses' short of the space available in network
-10.  If we were to combine these rules, they would need to be specified as
-follows:
-.LP
-.nf
-map ppp0 10.0.0.0/8 -> 209.1.2.0/24 portmap tcp/udp 1025:65000
-map ppp0 10.0.0.0/8 -> 209.1.2.0/24
-.fi
-.PP
-so that all TCP/UDP packets were port mapped and only other protocols, such as
-ICMP, only have their IP# changed.  In some instances, it is more appropriate
-to use the keyword \fBauto\fP in place of an actual range of port numbers if
-you want to guarantee simultaneous access to all within the given range.
-However, in the above case, it would default to 1 port per IP address, since
-we need to squeeze 24 bits of address space into 8.  A good example of how
-this is used might be:
-.LP
-.nf
-map ppp0 172.192.0.0/16 -> 209.1.2.0/24 portmap tcp/udp auto
-.fi
-.PP
-which would result in each IP address being given a small range of ports to
-use (252).  In all cases, the new port number that is used is deterministic.
-That is, port X will always map to port Y.
-WARNING: It is not advisable to use the \fBauto\fP feature if you are map'ing
-to a /32 (i.e. 0/32) because the NAT code will try to map multiple hosts to
-the same port number, outgoing and ultimately this will only succeed for one
-of them.
-The problem here is that the \fBmap\fP directive tells the NAT
-code to use the next address/port pair available for an outgoing connection,
-resulting in no easily discernible relation between external addresses/ports
-and internal ones.  This is overcome by using \fBmap-block\fP as follows:
-.LP
-.nf
-map-block ppp0 172.192.0.0/16 -> 209.1.2.0/24 ports auto
-.fi
-.PP
-For example, this would result in 172.192.0.0/24 being mapped to 209.1.2.0/32
-with each address, from 172.192.0.0 to 172.192.0.255 having 252 ports of its
-own.  As opposed to the above use of \fBmap\fP, if for some reason the user
-of (say) 172.192.0.2 wanted 260 simultaneous connections going out, they would
-be limited to 252 with \fBmap-block\fP but would just \fImove on\fP to the next
-IP address with the \fBmap\fP command.

 .SH NAME
 ippool, ippool.conf \- IP Pool file format
 .SH DESCRIPTION
-The format for files accepted by ippool is described by the following grammar:
-.LP
+The file ippool.conf is used with ippool(8) to configure address pools for
+use with ipnat(8) and ipf(8).
+.PP
+There are four different types of address pools that can be configured
+through ippool.conf. The various types are presented below with a brief
+description of how they are used:
+.HP
+dstlist
+.IP
+destination list - is a collection of IP addresses with an optional
+network interface name that can be used with either redirect (rdr) rules
+in ipnat.conf(5) or as the destination in ipf.conf(5) for policy based
+routing.
+.HP
+group-map
+.IP
+group maps - support the srcgrpmap and dstgrpmap call functions in
+ipf.conf(5) by providing a list of addresses or networks rule group
+numbers to start processing them with.
+.HP
+hash
+.IP
+hash tables - provide the means for performing a very efficient
+lookup address or network when there is expected to be only one
+exact match. These are best used with more static sets of addresses
+so they can be sized optimally.
+.HP
+pool
+.IP
+address pools - are an alternative to hash tables that can perform just
+as well in most circumstances. In addition, the address pools allow for
+heirarchical matching, so it is possible to define a subnet as matching
+but then exclude specific addresses from it.
+.SS
+Evolving Configuration
+.PP
+Over time the configuration syntax used by ippool.conf(5) has evolved.
+Originally the syntax used was more verbose about what a particular
+value was being used for, for example:
+.PP
 .nf
-line ::= table | groupmap .
-table ::= "table" role tabletype .
-groupmap ::= "group-map" inout role number ipfgroup
-tabletype ::= ipftree | ipfhash .
-
-role ::= "role" "=" "ipf" .
-inout ::= "in" | "out" .
-
-ipftree ::= "type" "=" "tree" number "{" addrlist "}" .
-ipfhash ::= "type" "=" "hash" number hashopts "{" hashlist "}" .
-
-ipfgroup ::= setgroup hashopts "{" grouplist "}" |
-             hashopts "{" setgrouplist "}" .
-setgroup ::= "group" "=" groupname .
-
-hashopts ::= size [ seed ] | seed .
-
-size ::= "size" number .
-seed ::= "seed" number .
-
-addrlist ::= [ "!" ] addrmask ";" [ addrlist ] .
-grouplist ::= groupentry ";" [ grouplist ] | addrmask ";" [ grouplist ] .
-
-setgrouplist ::= groupentry ";" [ setgrouplist ] .
-
-groupentry ::= addrmask "," setgroup .
-
-hashlist ::= hashentry ";" [ hashlist ] .
-hashentry ::= addrmask .
-
-addrmask ::= ipaddr | ipaddr "/" mask .
-
-mask ::= number | ipaddr .
-
-groupname ::= number | name .
-
-number ::= digit { digit } .
-
-ipaddr  = host-num "." host-num "." host-num "." host-num .
-host-num = digit [ digit [ digit ] ] .
-
-digit ::= "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9" .
-name ::= letter { letter | digit } .
+table role = ipf type = tree number = 100
+        { 1.1.1.1/32; !2.2.0.0/16; 2.2.2.0/24; ef00::5/128; };
 .fi
 .PP
-The IP pool configuration file is used for defining a single object that
-contains a reference to multiple IP address/netmask pairs.  A pool may consist
-of a mixture of netmask sizes, from 0 to 32.
-.PP
-At this point in time, only IPv4 addressing is supported.
-.TP
-.SH OVERVIEW
-.PP
-The IP pool configuration file provides for defining two different mechanisms
-for improving speed in matching IP addresses with rules.
-The first,
-.B table
-, defines a lookup
-.I table
-to provide a single reference in a
-filter rule to multiple targets and the second,
-.B group-map
-, provides a mechanism to target multiple groups from a single filter line.
-.PP
-The
-.B group-map
-command can only be used with filter rules that use the
-.B call
-command to invoke either
-.B fr_srcgrpmap
-or
-.B fr_dstgrpmap
-, to use the source or destination address,
-respectively, for determining which filter group to jump to next for
-continuation of filter packet processing.
-.SH POOL TYPES
-.PP
-Two storage formats are provided: hash tables and tree structure.  The hash
-table is intended for use with objects all containing the same netmask or a
-few different sized netmasks of non-overlapping address space and the tree
-is designed for being able to support exceptions to a covering mask, in
-addition to normal searching as you would do with a table.  It is not possible
-to use the tree data storage type with
-.B group-map
-configuration entries.
-.SH POOL ROLES
-.PP
-When a pool is defined in the configuration file, it must have an associated
-role.  At present the only supported role is
-.B ipf.
-Future development will see futher expansion of their use by other sections
-of IPFilter code.
-.SH EXAMPLES
-The following examples show how the pool configuration file is used with
-the ipf configuration file to enhance the ability for the ipf configuration
-file to be succinct in meaning.
-.TP
-1
-The first example shows how a filter rule makes reference to a specific
-pool for matching of the source address.
+This is rather long winded. The evolution of the configuration syntax
+has also replaced the use of numbers with names, although numbers can
+still be used as can be seen here:
+.PP
 .nf
-pass in from pool/100 to any
+pool ipf/tree (name "100";)
+	{ 1.1.1.1/32; !2.2.0.0/16; 2.2.2.0/24; ef00::5/128; };
 .fi
 .PP
-The pool configuration, which matches IP addresses 1.1.1.1 and any
-in 2.2.0.0/16, except for those in 2.2.2.0/24.
+Both of the above examples produce the same configuration in the kernel
+for use with ipf.conf(5).
+.PP
+Newer options for use in ippool.conf(5) will only be offered in the new
+configuration syntax and all output using "ippool -l" will also be in the
+new configuration syntax.
+.SS
+IPFilter devices and pools
+.PP
+To cater to different administration styles, ipool.conf(5) allows you to
+tie a pool to a specific role in IPFilter. The recognised role names are:
+.HP
+ipf
+.IP
+pools defined for role "ipf" are available for use with all rules that are
+found in ipf.conf(5) except for auth rules.
+.HP
+nat
+.IP
+pools defined for role "nat" are available for use with all rules that are
+found in ipnat.conf(5).
+.HP
+auth
+.IP
+pools defined for role "auth" are available only for use with "auth" rules
+that are found in ipf.conf(5)
+.HP
+all
+.IP
+pools that are defined for the "all" role are available to all types of
+rules, be they NAT rules in ipnat.conf(5) or firewall rules in ipf.conf(5).
+.SH Address Pools
+.PP
+An address pool can be used in ipf.conf(5) and ipnat.conf(5) for matching
+the source or destination address of packets. They can be referred to either
+by name or number and can hold an arbitrary number of address patterns to
+match.
+.PP
+An address pool is considered to be a "tree type". In the older configuration
+style, it was necessary to have "type=tree" in ippool.conf(5). In the new
+style configuration, it follows the IPFilter device with which the pool
+is being configured.
+Now it is the default if left out.
+.PP
+For convenience, both IPv4 and IPv6 addresses can be stored in the same
+address pool. It should go without saying that either type of packet can
+only ever match an entry in a pool that is of the same address family.
+.PP
+The address pool searches the list of addresses configured for the best
+match. The "best match" is considered to be the match that has the highest
+number of bits set in the mask. Thus if both 2.2.0.0/16 and 2.2.2.0/24 are
+present in an address pool, the addres 2.2.2.1 will match 2.2.2.0/24 and
+2.2.1.1 will match 2.2.0.0/16. The reason for this is to allow exceptions
+to be added through the use of negative matching. In the following example,
+the pool contains "2.2.0.0/16" and "!2.2.2.0/24", meaning that all packets
+that match 2.2.0.0/16, except those that match 2.2.2.0/24, will be considered
+as a match for this pool.
 .PP
-.nf
 table role = ipf type = tree number = 100
-        { 1.1.1.1/32; 2.2.0.0/16; !2.2.2.0/24 };
+        { 1.1.1.1/32; 2.2.0.0/16; !2.2.2.0/24; ef00::5/128; };
+.PP
+For the sake of clarity and to aid in managing large numbers of addresses
+inside address pools, it is possible to specify a location to load the
+addresses from. To do this simply use a "file://" URL where you would
+specify an actual IP address.
+.PP
+.nf
+pool ipf/tree (name rfc1918;) { file:///etc/ipf/rfc1918; };
 .fi
-.TP
-2
-The following ipf.conf extract uses the
-fr_srcgrpmap/fr_dstgrpmap lookups to use the
-.B group-map
-facility to lookup the next group to use for filter processing, providing
-the
-.B call
-filter rule is matched.
+.PP
+The contents of the file might look something like this:
+.PP
 .nf
-call now fr_srcgrpmap/1010 in all
-call now fr_dstgrpmap/2010 out all
-pass in all group 1020
-block in all group 1030
-pass out all group 2020
-block out all group 2040
+# RFC 1918 networks
+10.0.0.0/8
+!127.0.0.0/8
+172.16.0.0/12
+192.168.0.0/24
 .fi
 .PP
-A ippool configuration to work with the above ipf.conf file might
-look like this:
+In this example, the inclusion of the line "!127.0.0.0/8" is, strictly
+speaking not correct and serves only as an example to show that negative
+matching is also supported in this file.
+.PP
+Another format that ippool(8) recognises for input from a file is that
+from whois servers. In the following example, output from a query to a
+WHOIS server for information about which networks are associated with
+the name "microsoft" has been saved in a file named "ms-networks".
+There is no need to modify the output from the whois server, so using
+either the whois command or dumping data directly from it over a TCP
+connection works perfectly file as input.
+.PP
+.nf
+pool ipf/tree (name microsoft;) { whois file "/etc/ipf/ms-networks"; };
+.fi
+.PP
+And to then block all packets to/from networks defined in that file,
+a rule like this might be used:
+.PP
+.nf
+block in from pool/microsoft to any
+.fi
+.PP
+Note that there are limitations on the output returned by whois servers
+so be aware that their output may not be 100% perfect for your goal.
+.SH Destination Lists
+.PP
+Destination lists are provided for use primarily with NAT redirect rules
+(rdr). Their purpose is to allow more sophisticated methods of selecting
+which host to send traffic to next than the simple round-robin technique
+that is present with with "round-robin" rules in ipnat.conf(5).
+.PP
+When building a list of hosts to use as a redirection list, it is
+necessary to list each host to be used explicitly. Expressing a
+collection of hosts as a range or a subnet is not supported. With each
+address it is also possible to specify a network interface name. The
+network interface name is ignored by NAT when using destination lists.
+The network itnerface name is currently only used with policy based
+routing (use of "to"/"dup-to" in ipf.conf(5)).
+.PP
+Unlike the other directives that can be expressed in this file, destination
+lists must be written using the new configuration syntax. Each destination
+list must have a name associated with it and a next hop selection policy.
+Some policies have further options. The currently available selection
+policies are:
+.HP
+round-robin
+.IP
+steps through the list of hosts configured with the destination list
+one by one
+.HP
+random
+.IP
+the next hop is chosen by random selection from the list available
+.HP
+src-hash
+.IP
+a hash is made of the source address components of the packet
+(address and port number) and this is used to select which
+next hop address is used
+.HP
+dst-hash
+.IP
+a hash is made of the destination address components of the packet
+(address and port number) and this is used to select which
+next hop address is used
+.HP
+hash
+.IP
+a hash is made of all the address components in the packet
+(addresses and port numbers) and this is used to select which
+next hop address is used
+.HP
+weighted
+.IP
+selecting a weighted policy for destination selection needs further
+clarification as to what type of weighted selection will be used.
+The sub-options to a weighted policy are:
+.RS
+.HP
+connection
+.IP
+the host that has received the least number of connections is selected
+to be the next hop. When all hosts have the same connection count,
+the last one used will be the next address selected.
+.RE
+.PP
+The first example here shows 4 destinations that are used with a
+round-robin selection policy.
+.PP
+.nf
+pool nat/dstlist (name servers; policy round-robin;)
+        { 1.1.1.2; 1.1.1.4; 1.1.1.5; 1.1.1.9; };
+.fi
+.PP
+In the following example, the destination is chosen by whichever has
+had the least number of connections. By placing the interface name
+with each address and saying "all/dstlist", the destination list can
+be used with both ipnat.conf(5) and ipf.conf(5).
+.PP
+.nf
+pool all/dstlist (name servers; policy weighted connection;)
+        { bge0:1.1.1.2; bge0:1.1.1.4; bge1:1.1.1.5; bge1:1.1.1.9; };
+.fi
+.SH Group maps
+.PP
+Group maps are provided to allow more efficient processing of packets
+where there are a larger number of subnets and groups of rules for those
+subnets. Group maps are used with "call" rules in ipf.conf(5) that
+use the "srcgrpmap" and "dstgrpmap" functions.
+.PP
+A group map declaration must mention which group is the default group
+for all matching addresses to be applied to. Then inside the list of
+addresses and networks for the group, each one may optionally have
+a group number associated with it. A simple example like this, where
+the first two entries would map to group 2020 but 5.0.0.0/8 sends
+rule processing to group 2040.
 .PP
 .nf
-group-map in role = ipf number = 1010
-	{ 1.1.1.1/32, group = 1020; 3.3.0.0/16, group = 1030; };
 group-map out role = ipf number = 2010 group = 2020
-	{ 2.2.2.2/32; 4.4.0.0/16; 5.0.0.0/8, group = 2040; };
+        { 2.2.2.2/32; 4.4.0.0/16; 5.0.0.0/8, group = 2040; };
+.fi
+.PP
+An example that outlines the real purpose of group maps is below,
+where each one of the 12 subnets is mapped to a different group
+number. This might be because each subnet has its own policy and
+rather than write a list of twelve rules in ipf.conf(5) that match
+the subnet and branch off with a head statement, a single rule can
+be used with this group map to achieve the same result.
+.PP
+.nf
+group-map ( name "2010"; in; )
+    { 192.168.1.0/24, group = 10010; 192.168.2.0/24, group = 10020;
+      192.168.3.0/24, group = 10030; 192.168.4.0/24, group = 10040;
+      192.168.5.0/24, group = 10050; 192.168.6.0/24, group = 10060;
+      192.168.7.0/24, group = 10070; 192.168.8.0/24, group = 10080;
+      192.168.9.0/24, group = 10090; 192.168.10.0/24, group = 10100;
+      192.168.11.0/24, group = 10110; 192.168.12.0/24, group = 10120;
+    };
+.fi
+.PP
+The limitation with group maps is that only the source address or the
+destination address can be used to map the packet to the starting group,
+not both, in your ipf.conf(5) file.
+.SH Hash Tables
+.PP
+The hash table is operationally similar to the address pool. It is
+used as a store for a collection of address to match on, saving the
+need to write a lengthy list of rules. As with address pools, searching
+will attempt to find the best match - an address specification with the
+largest contiguous netmask.
+.PP
+Hash tables are best used where the list of addresses, subnets and
+networks is relatively static, which is something of a contrast to
+the address pool that can work with either static or changing
+address list sizes.
+.PP
+Further work is still needed to have IPFilter correctly size and tune
+the hash table to optimise searching. The goal is to allow for small to
+medium sized tables to achieve close to O(1) for either a positive or
+negative match, in contrast to the address pool, which is O(logn).
+.PP
+The following two examples build the same table in the kernel, using
+the old configuration format (first) and the new one (second).
+.PP
+.nf
+table role=all type=hash name=servers size=5
+        { 1.1.1.2/32; 1.1.1.3/32; 11.23.44.66/32; };
+
+pool all/hash (name servers; size 5;)
+	{ 1.1.1.2; 1.1.1.3; 11.23.44.66; };

- * The data structure for the keys is a radix tree with one way
- * branching removed.  The index rn_b at an internal node n represents a bit
- * position to be tested.  The tree is arranged so that all descendants
- * of a node n have keys whose bits all agree up to position rn_b - 1.
- * (We say the index of n is rn_b.)
- *
- * There is at least one descendant which has a one bit at position rn_b,
- * and at least one with a zero there.
- *
- * A route is determined by a pair of key and mask.  We require that the
- * bit-wise logical and of the key and mask to be the key.
- * We define the index of a route to associated with the mask to be
- * the first bit number in the mask where 0 occurs (with bit number 0
- * representing the highest order bit).
- *
- * We say a mask is normal if every bit is 0, past the index of the mask.
- * If a node n has a descendant (k, m) with index(m) == index(n) == rn_b,
- * and m is a normal mask, then the route applies to every descendant of n.
- * If the index(m) < rn_b, this implies the trailing last few bits of k
- * before bit b are all 0, (and hence consequently true of every descendant
- * of n), so the route applies to all descendants of the node as well.
- *
- * Similar logic shows that a non-normal mask m such that
- * index(m) <= index(n) could potentially apply to many children of n.
- * Thus, for each non-host route, we attach its mask to a list at an internal
- * node as high in the tree as we can go.
- *
- * The present version of the code makes use of normal routes in short-
- * circuiting an explicit mask and compare operation when testing whether
- * a key satisfies a normal route, and also in remembering the unique leaf
- * that governs a subtree.

+ * This file defines data structures for different types of trees:
+ * splay trees and red-black trees.
+ *
+ * A splay tree is a self-organizing data structure.  Every operation
+ * on the tree causes a splay to happen.  The splay moves the requested
+ * node to the root of the tree and partly rebalances it.
+ *
+ * This has the benefit that request locality causes faster lookups as
+ * the requested nodes move to the top of the tree.  On the other hand,
+ * every lookup causes memory writes.
+ *
+ * The Balance Theorem bounds the total access time for m operations
+ * and n inserts on an initially empty tree as O((m + n)lg n).  The
+ * amortized cost for a sequence of m accesses to a splay tree is O(lg n);
+ *
+ * A red-black tree is a binary search tree with the node color as an
+ * extra attribute.  It fulfills a set of conditions:
+ *	- every search path from the root to a leaf consists of the
+ *	  same number of black nodes,
+ *	- each red node (except for the root) has a black parent,
+ *	- each leaf node is black.
+ *
+ * Every operation on a red-black tree is bounded as O(lg n).
+ * The maximum height of a red-black tree is 2lg (n+1).
