modem issue

[Cakeboy]

Wondered if anyone knows how to configure a speedtouch 585v6 router so I can play online via a netgear usb stick. Whenever I try to go online with pes2008 it says something about port 5730, port mapping, assign dmz (?). I've no bloody idea what it means.
Needless to say I'm f£$ked off. Any advice would be appreciated.
