I am trying to setup a Windows VPN between a Vista PC that is behind a linksys WRV54G router and a Windows 7 laptop. I cannot get the Win 7 client to connect to the PC after setting up the connections on both ends. I have enabeled IPSEC,PPTP and L2TP passthrough and disabled the router's VPN Tunnel. In UPNP forwarding, I have enabled port 1723 for TCP for the Vista PC. When I attempt to connect to the Vista PC from the laptop using the router's IP address, I receive an error that said the VPN connection could not be made and that a setting may be incorrect. Are there any additional setting that I need to change on this router,PC or laptop to complete this connection? Thanks in advance for any help
