you could have a strict or moderate NAPT connection. i had this problem if you have a strit NAPT connect you will find it hard to connect to a match. realy you will have a greater sucess by changing it to a open connection. and as far as im aware there are 2 ways to do this.
simple way would be to change your modem router to a MS recoginsed one. i had this problem. i was using my BT Broadband router, then i changed in to my D-LINK that i got with my xbox live set up pack for old xbox and i had alot more sucess.
or you couldtry this allought ive not tested in my self.
modify your firewall to allow network connection to these ports:
or it could just all be down to COD2
hope this helps
