Question : Changing pptp port

Is it possible to change the default port in windows XP Pro for PPTP. I am trying to set up a vpn connection with my two servers on one router. I have PPTP port 1723 forwarding to one one of the servers. I want to set it up so I can use PPTP to get to the other server also using a different port.

Answer : Changing pptp port

PPTP establishes connection on TCP port 1723. This cannot be changed.
Once the connection is made, the actual tunnel is over GRE which cannot be port-forwarded. Most routers will support one and only one GRE tunnel at a time.
