I have set up PPTP VPN through a m0n0wall to windows 2003 server. The VPN connection works and authiticates perfectly. On the remote PC if I type ipconfig /all in a DOS box, everything is correct except the subnet which is 255.255.255.255 I can't access any machine on the 192.168 network even pinging.

What have I missed?

I just remote connected to my PPTP VPN and did an  IPCONFIG /all and my subnet is 255.255.255.255 as well. But I have no problems pinging anything on the other side of the VPN server etc....

Make sure your lan subnet are not the same for eg 192.168.2.1 and on the other side you could have 192.168.3.1. If there both xxx.xxx.2.1 on both sides you have a problem. Also make sure the correct ports are open on the side that has the server running RRAS.

Let me know...

On what ever side your hosting the VPN make sure port forwarding is on for PPTP 1723/1723

The PC I'm testing with is connected to one of my extra external IPs so it is definately not on the same subnet as my LAN. I'm beginning to suspect I don't have my rules configured correctly.
