Re: How to forward gre - VPN server behind windows server 2003

16.1 and 1.1 are both on a Windows server 2003 machine and there are no ISPs. I'm testing in LAN environment. the Windows server 2003 is running a proxy to regulate the internal traffic and also has a mapped link for the TCP port 1723 to the VPN server.

Doesn't win2k3 have a built in firewall? Try turning it off and see if your GRE traffic makes it to the other side.

Firewall is off with no filters. I'm 99% sure. Gonna check tomorrow morning.

If that doesn't work - have you tried connecting your vpn client directly to the vpn server for a sanity check?

Just tested it. VPN functions normaly when connecting from External client to Windows Server and Windows server to Internal VPN server. all firewalls are off.

A bit of an update. The packets not getting to the Internal VPN server are displayed in wireshark as protocol: "ppp lcp" with info: configuration request
