set up VPN

I’m having trouble setting up a Win2K VPN Server. Thought I did it right, but cannot connect.

Win2k server has two NICs. One is the wireless card getting the IP from the access router. Router config’ed to pass port 1723. Server is dual-homed. Nic connected to Router is on 192.168.1.0 network, Nic connected to LAN is on 192.168.100.0 network. I can RDP to this server too. But attempts to make a pptp connection fail.

Please help!!!
