Every time I try to play online games, a screen pops up ans states the following; "Internal IP address is different than its external IP address. This maybe caused by firewalls, a NAT proxies, or other unusual network configurations and may prevent you from hosting a game". Even though I skip pass this screen and launch the online game, I still can't connect to the online game server or I get knocked off. Currently I am using Windows XP Home version and Dell TrueMobil Wireless Router w/ built in firewall. THe firewall in XP is not in use at the time of the contuined error. Any ideas??? Thanks!!
