MW2 for PC NAT Problems
MW2 has been working fine when hosting games, until now. A few days ago, the router was having problems (WRT54G v4.0, was on DD-WRT), so I reset all of the settings. I then restored it back to the stock firmware (from DD-WRT), which a lot of you will probably think is crazy. I just don't need DD-WRT.
MW2 used to tell me that my NAT is "OPEN", but now it says it's "STRICT". I have UPnP enabled. Anything else I should try? If I have to, I'll go back to DD-WRT.
