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.
