Server 2008 R2 VPN and windows 7 problems

Posted on 2011-10-11

Hi there,
We've setup a 2008 R2 server for VPN with an outward facing FQDN that points to the server inside our network. We can connect fine inside the network, but despite our ISP (our local education authority) freeing up TCP ports 443 and 1731, and UDP ports 4500 and 1701, we have problems connecting to it using either SSTP, PPTP or LK2p VPN transport types. Firewalls are switched off on both the server and the client. Any ideas?

    Can you ping the FQDN from the outside?

    ISP/LEA has disabled pinging on the redirection, but we can see the IIS welcome page, so I'm assuming it can be seen.

    Well I guess so. Still seems to be an issue with port being blocked

    Default port for PPTP is TCP 1723, is this unblocked? Also UDP 47

    Sorted. Turns out GRE needed to be enabled on our router. Works like a charm now. Thanks for all your help
