-.Os FreeBSD
-.Sh NAME
-.Nm ng_pptpgre
-.Nd PPTP GRE protocol netgraph node type
-.Sh SYNOPSIS
-.Fd #include <netgraph/ng_pptpgre.h>
-.Sh DESCRIPTION
-The
-.Nm pptpgre
-node type performs Generic Routing Encapsulation (GRE) over IP
-for the PPTP protocol as specified by RFC 2637.  This involves packet
-encapsulation, sequencing, acknowlegement, and an adaptive timeout
-sliding window mechanism.  This node type does not handle any of
-the TCP control protocol or call negotiation defined by PPTP.
-.Pp
-This node type expects to receive complete IP packets,
-including the IP header, on the
-.Dv lower
-hook, but it transmits outgoing frames without any IP header.
-The typical use for this node type would be to connect the
-.Dv upper
-hook to one of the link hooks of a
-.Xr ng_ppp 4
-node, and the
-.Dv lower
-hook to the
-.Dv "inet/raw/gre"
-hook of a
-.Xr ng_ksocket 4
-node.
-.Sh HOOKS
-This node type supports the following hooks:
-.Pp
-.Bl -tag -compact -width vjc_vjuncomp
-.It Dv upper
-Connection to the upper protocol layers
-.It Dv lower
-Connection to the lower protocol layers
-.El
-.Pp
-.Sh CONTROL MESSAGES
-This node type supports the generic control messages, plus the following:
-.Bl -tag -width foo
-.It Dv NGM_PPTPGRE_SET_CONFIG
-This command resets and configures the node for a session.
-This command takes a
-.Dv "struct ng_pptpgre_conf"
-as an argument:
-.Bd -literal -offset 0
-/* Configuration for a session */
-struct ng_pptpgre_conf {
-    u_char      enabled;          /* enables traffic flow */
-    u_char      enableDelayedAck; /* enables delayed acks */
-    u_int16_t   cid;              /* my call id */
-    u_int16_t   peerCid;          /* peer call id */
-    u_int16_t   recvWin;          /* peer recv window size */
-    u_int16_t   peerPpd;          /* peer packet processing delay
-                                     (in 1/10 of a second) */
-};
-
-.Ed
-The
-.Dv enabled
-field enables traffic flow through the node.  The
-.Dv enableDelayedAck
-field enables delayed acknowledgement (maximum 250 miliseconds), which
-is a useful optimization and should generally be turned on.
-The remaining fields are as supplied by the PPTP virtual call setup process.
-.It Dv NGM_PPTPGRE_GET_CONFIG
-Returns the current configuration as a
-.Dv "struct ng_pptpgre_conf" .
-.It Dv NGM_PPTPGRE_GET_STATS
-This command returns a
-.Dv "struct ng_pptpgre_stats"
-containing various node statistics.
-.It Dv NGM_PPTPGRE_CLR_STATS
-This command resets the node statistics.
-.It Dv NGM_PPTPGRE_GETCLR_STATS
-This command atomically gets and resets the node statistics, returning a
-.Dv "struct ng_pptpgre_stats" .
-.El
-.Sh SHUTDOWN
-This node shuts down upon receipt of a
-.Dv NGM_SHUTDOWN
-control message, or when both hooks have been disconnected.

-.Sh BUGS
-The node should not expect incoming GRE packets to have an IP header.
-This behavior is inherited from the (converse) behavior of raw IP sockets.
-An intermediate node that strips IP headers in one direction
-should be used instead.
-.Sh HISTORY
-The
-.Nm
-node type was implemented in
-.Fx 4.0 .
