Problem connecting to Win2K VPN Server behind Win2K NAT
Posted on 2004-04-08
I have a Windows 2000 VPN server ... behind a Windows 2000 NAT server ... on the NAT server I have reserved one public IP for the private IP of the VPN server and allowed incoming sessions.
From Internet I can reach the VPN server through telnet/web/ftp services, I can browse from the VPN server and initiate outbound VPN connections too. But when I try to initiate inbound connections from Internet to this VPN server, it fails saying that it has not found a valid certificate. But when I try to connect to the VPN server from inside my Intranet, I get through.
What could be the possible cause and remedy.

How do I exactly do this ?
I have reserved the public IP address x.x.x.x for the internal IP address y.y.y.y
On the NAT router I have two cards, NIC named "Internet" connecting to Internet and "Intranet" connecting to my LAN.
Should I go to Routing and Remote Access in the NAT router and go to IP Routing -> Network Address Translation -> Properties of the interface "Internet" -> Special Ports ?
What should be the entries when I want to add a special port like:
1. "On this interface" or "On this address pool entry" - Which one to select ?
2. Incoming port and Outgoing port.
