This should be fairly easy for those with a good knowledge of Win2003 and VPN. I've got VPN running fine, and my family are able to access my network via it. Only issue is, I want to lock down my server because it's currently wide open due to the DMZ. If I close this, VPN won't obviously work - I've been trying to find the ports that VPN uses, so to open them up via the firewall and port-forward to the server, but cannot find this information anywhere unfortunately. Anyone happening to know this answer would be top of my Christmas card list, and well worthy of a beer or two.

Thanks in advance.

Its not that simple because PPTP uses TCp port 1723, and GRE (protocol 47) which has no concept of ports, so you can't forward the appropriate ports.

What are you using for firewall/router? On some, you can forward just port 1723 and GRE (Cisco for sure)
