It is similar to natd(8) 2011-06-14T13:35:24Z Andrey V. Elsukov ae@FreeBSD.org 2011-06-14T13:35:24Z urn:sha1:1875bbfe5418f8247ad06770b63089be636ff9f7 "globalport" option for multiple NAT instances. If ipfw rule contains "global" keyword instead of nat_number, then for each outgoing packet ipfw_nat looks up translation state in all configured nat instances. If an entry is found, packet aliased according to that entry, otherwise packet is passed unchanged. User can specify "skip_global" option in NAT configuration to exclude an instance from the lookup in global mode. PR: kern/157867 Submitted by: Alexander V. Chernikov (previous version) Tested by: Eugene Grosbein Sort alias mode flags in the increasing order. 2011-06-14T12:06:38Z Andrey V.

During startup (and after every HUP signal) user land applications running the new libalias will try to read a file in /etc called libalias.conf: that file contains the list of modules to load. User land applications affected by this commit are ppp and natd: if libalias.conf is present in /etc you won't notice any difference. The only kernel land bit affected by this commit is ng_nat: if you are using ng_nat, and it doesn't correctly handle ftp/irc/etcetc sessions anymore, remember to kldload the correspondent module (i.e. kldload alias_ftp). General information and details about the inner working are available in the libalias man page under the section 'MODULAR ARCHITECTURE (AND ipfw(4) SUPPORT)'. NOTA BENE: this commit affects _ONLY_ libalias, ipfw in-kernel nat support will be part of the next libalias-related commit.
