Trouble with VPN over PPTP in regards to Port Forwarding TCP 1723

Asked by AdamHolmes in Networking Hardware Firewalls, Virtual Private Networking (VPN), Miscellaneous Networking

Tags: port, pptp, vpn, 1723

I am trying to port forward for a VPN over PPTP. I've done this in the past by simply port forwarding TCP 1723; however, in my current situation it doesn't seem to be working.

What I have done:
-Enabled Routing & Remote Access on a Windows 2003 Server
-Tested the VPN connection inside the local network with success
-Port Forwarded TCP 1723 on the router
-Tested other port forwards on the router successfully (port 80, 443, etc)
-Attempted unsuccessfully to access from outside the router. I get to the Verifying Username & Password screen, but never any further. I would assume this shows that I'm having an issue with GRE 47, but I wasn't aware that I had to do anything to enable this protocol; moreover, on the firewall there is no option to enable this.

Any ideas?
