e.g.

• You: 6112
• Him: 6113

Then on your router, you forward port 6112 for UDP to your LAN IP and port 6113 for UDP to your brother's LAN IP.|||U need to change teh game port on 1 of the pcs as using teh same port will not work
eg pc 1 - goes though port 6112 pc needs to go though port 6113 for instance and set up.
you can change the ports in gpgnet by doing the following,
Tools, options, game setting (just click on the word not the cross)
and in there you will see game port just change that to 6113 for the other pc and you should be fine
