We have a point-to-point T1 connection between two CISCO 2800 routers. One side has a static IP and the other has a Dynamic IP. The client wants their Server in the location that has a dynamic IP. So the problem is that we need mail to go to the exchange server but ip address at that location is dynamic. Can anyone give a sample cisco config on what statements you would need to have port 25 be forwarded accross the p-to-p T1 to the Server from the site that has a static IP address? Any help would be greatly appreciated.
