linksys wireless router game ports

Xbox Live Party won’t connect with Windstream?

I have a Speedstream 4200 modem with the Ethernet connected to a Linksys wireless router. MW2 says that I have Open NAT, but I can’t join any of my friend’s parties nor can I join their game lobbies. I have tried disabling the firewall and opening up ports with no success, any other suggestions?
