A significant rewrite of PPTP aliasing code.

2000-10-30T12:39:41Z

PPTP links are no longer dropped by simple (and inappropriate in this case) "inactivity timeout" procedure, only when requested through the control connection. It is now possible to have multiple PPTP servers running behind NAT. Just redirect the incoming TCP traffic to port 1723, everything else is done transparently. Problems were reported and the fix was tested by: Michael Adler , David Andersen

- Do not modify Peer's Call ID in outgoing Incoming-Call-Connected

Added true support for PPTP aliasing. Some nice features include:

2000-06-20T11:41:48Z

- Multiple PPTP clients behind NAT to the same or different servers. - Single PPTP server behind NAT -- you just need to redirect TCP port 1723 to a local machine. Multiple servers behind NAT is possible but would require a simple API change. - No API changes! For more information on how this works see comments at the start of the alias_pptp.c. PacketAliasPptp() is no longer necessary and will be removed soon. Submitted by: Erik Salander Reviewed by: ru Rewritten by: ru Reviewed by: Erik Salander
