Help me Please
 

Hi everyone, my problem is with the router i currently use (BELKIN F5D5231-4) to share my telewest broadband connection with my xbox 360 for xbox live. I am currently expieriencing moderate NAT which is preventing me getting the full effect of the service. I have tried various things like forwarding ports and using the DMZ funcion of the router but nothing seems to work. Is there anyone who has had the same problem as me that could help me get use from the router before i throw it out the window in frustration.

Thx
