I am currently testing Windows Server 2008.Internally, everything works OK.Externally, I can get to DNS, HTTP[S], etc. with no problems.What I can not do is to connect via VPN.The remote system reports that the server is not responding.The server is connected to the internet via a Linksys router. The router redirects various ports to the internal (192.168.1.x) address of the server.Obviously, I need to redirect some additional ports.Can someone point me to the additional ports & protocols I need to redirect in order to make the VPN operational?Thanks.John P.

Hello, Thanks Syed for the information sharing. Based on my experience, to pass PPTP VPN though Linksys NAT device, you need to open TCP Port 1723. And for some kinds of routers, you might need to disable PPTP VPN Service on the router first. I recommend you contact to Linksys support directly regarding how to configure the router to pass-through VPN connection if the above information doesnt help. Thanks.
