Im having a lot of problems setting up a vpn server using only one NIC I have a router followed by the server. I want to be able to connect to is and see the network. I have installed the routing and remote roll with VPN and routing and did a custom config. However when I try to connect I always get an 812 error. I made sure to forward the ports in the router. I searched for a guide but i couldnt find anything. Can someone link me to one or help me get this working? TIA

Error 812 is an authentication error. Before you try connecting from a remote computer, make a VPN connection to the server from a local workstation using the server's local IP address. (VPN works over any IP connection). This will allow you to debug this problem locally. Bill

Hi brianmay277 , Thanks for post here. Could you describe in detail that how did you config VPN service and What custom configurations you set on RRAS server ? For how to troubleshoot Error 812 please reference the article below : Error Code: 732, 734, 812 http://blogs.technet.com/b/rrasblog/archive/2009/08/12/troubleshooting-common-vpn-related-errors.aspx How to configure VPN Server with single NIC on Windows Server http://blogs.technet.com/b/rrasblog/archive/2006/06/19/how-to-configure-vpn-server-with-single-nic-on-windows-server.aspx Thanks.
