Games can't be played on wireless... I better disconnect my wireless then and stop playing DoW, Ravenshield, Eve online, City of Heros, and many others that I play. You must have meant games cannot be played accross an AD-HOC network connection, Which I'm not sure if it would work or not. I do play multiplayer games within my lan across wireless without any issues though. Chances are since it is on a "diffrent" wan that they are not on the same network and it IS a port forwarding issue.
