Its physically impossible to run two different servers from one port.... If TCP port 2593 is in use, its in use. This means you cant run 2 servers on same port on single connection. With two WAN connections on one machine its possible
If you really want to do this, id say look over for VMware server. Then just add two network adapters in your machine and fire it up :P that would be the best choice... Having two OS and two adapters... dunno
