Call of Duty 4 Problem...

Does playing regular matches against random people work?

If not then there is a huge amount of stuff that can be going wrong for you.

im a aus and this problem has been going on since a week after it was release so i would try a corded connection.

Every time I try to join a party or game with my friend, it says 'unable to connect to host'...is there any way to fix this?Zach68486

If your internet is fine, then it's probably Infinity Ward and their inferior skills of programming.

My NAT somehow was set to strict, and I think that's the problem.Zach68486
