VPN Client (PPtP) behind OpenBSD 3.0 doing NAT..

["Alex Slok" <pslok@chello.nl>]

Maybe this question has been wandering around this list, I'm not sure. I'll
still ask this one.

I'm running an OpenBSD 3.0 machine, doing NAT for my local lan. Now I'm
trying to set up a VPN connection to my company that is running a Windows NT
4.0 PPtP server from one of my clients..

The VPN client (Windows XP) on my Local LAN isn't working properly and hangs
with 'verifying username and password' Connecting with a client (also
Windows) that is directly connected to the internet works fine though, thus
it must be something with the NAT machine.

Now Í've read some articles on this subject, but the problem is that they
vary with solutions ... Is there a way to redirect the PPtP traffic from my
local client to the VPN server. Routing GRE traffic isn't possible within my
/etc/nat.conf (or is it ?). Maybe in a way like the ftp-proxy ???

Is there a way to overcome this one ??

Greetz,

Alex
