the nat type changes all of the time to either strict or moderate, and all we want to do is have it open all of the time. here is a few details the 360 is a new 250 slim model, i have call of duty elite so I have all of the map packs, oh and i am connected thru wifi, the only way that seems to work for the nat type to be open is we have to unplug the modem/router for 30 seconds. I dont want to do this anymore, so anyone please help.
