When you start the server, go into RF Setup on the Splash Screen, go to Force Local Port, and put it as 5588 (or whatever you want, just make sure it's also forced through any firewalls or routers you have). Start the Dedi. Then, go into the Splash screen, and change it 6688 (or whatever you want, just make sure it's also forced through any firewalls or routers you have)... then go and join it like you would a normal server!... Remember though that this leaves your computer particularly open to bad people...
