Ok, for the guys who i play with will now i got Moderate NAT when I play COD, and now trying to sort out my settings for it.
I play on wireless not sure if that matters in anyway.

Theres my port forward settings, that i got of portforward.com

and thats the firewall page.
Iv tried the 360 since i changed them, and still no difference, is there anything else i need to do?
CJ seems to know a bit about it all, so hopefully can help me
