Cisco 2524 Port Forwarding

I have a small network of computers that sits behind a Cisco 2524 Router (connected to a T1 Line). My problem is that I have set up VPN on a server (configured with a static private IP address of 10.0.0.X). I need to forward VPN ports to that computer but I am lost with the Cisco Setup (using ConfigMaker 2.6 and can see the router configuration). I just don’t know where to start at or if its even possible. The VPN uses TCP 1723 and UDP 1701 I believe.
