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.
