I have a BT Voyager 200 modem router. I would like to use the hardware firewall instead of a software one.
However, when I activate it I can't connect to xbox live. Apparently I have to open the following ports UDP 88, UDP 3074 and TCP 3074. Please could someone advise me how to do this. When I look in the settings it doesn't mention these ports anywhere. I phoned xbox support and they say I have to contact BT for them to open it even though I am a plusnet customer.
