In server only mode, your router must be configured to forward port 1723 to your server and must provide full support for protocol 47. Note that protocol 47 (GRE) is not a port and therefore you cannot forward it. Not all routers support this protocol so VPN is not always possible in this network arrangement.

In any point to point VPN connection, there will be numerous pieces of equipment that the signal passes through eg corporate firewalls, additional routers/firewalls, software firewalls/filters etc. All these steps in the chain must support protocol 47, if any piece of equipment in the chain does not support that protocol then the VPN connection will be unsuccessful. Sometimes these matters are out of the end users control, especially in corporate situations, or home user situations where low end broadband connections are used and ISP's limit functionality.
