WGT624v3 xbox live and some questions
 

ok i have a WGT624v3 this one

Hardware Version V3H1
Firmware Version V2.0.16_1.0.1

im in the uk and use virgin broadband xl

ok now heres my problem i have 3 360`s and when i have company round we all want to connect to xboxlive and play together but to get microsofts open connection (see here ) i have to forward ports now i can do that to only one ip so xbox 1 can get an open connection, i made xbox 2 a dmz ip (so its outside the firewall) doesnt always work lol and ofcourse xbox 3 is always strict

anyideas how i can fix it?
i notice that there is newer firmware for my router but it says north america only so im guessing it would be a bad idea to install on a uk router?


any help greatly recieved
