My wife bought her self an xbox last night so we can game togher. We both tried to get online last night, but came up with a strict nat for one of the machines. Which ever machine got online first got the open nat type. i've tried DMZ host with port forwarding for both machines to no success. We have a netgear modem router from charter cable. the model number I believe is CG3000D. she was on a wireless network and i was wired straight to the modem router. I was told that, that modem router couldn't support two xboxes which doesn't make sense to me.
