RE: D-Link Router and Multiplayer
Have a look here http://www.PortForward.com . I'm behind a router as well(linksys). You might find something there......sometimes a simple reset works. Go back to default settings, then just reinstate what you know will work. After a long battle with mine it seemms as though it had actually done (finally) what was needed to fix the problem, but the "left-overs" of previous attempts were conflicting the fix. This stuff is a real pain in the neck to all but the pros or the real lucky, of which I'm neither. Good luck
