I have a cox cable modem connected to an Airport Extreme base station (Wireless N). I am trying to play Age of Empires 3 and I am failing to join nearly every game. I opened all the ports (UDP: 2300-2310, TCP: 80, 2300), but I am still having issues. Now, if I plug my computer directly into the modem, it works fine. How can I remove all the protection from my airport extreme so that I can connect to these games? Is there a way simply to make it act as a router without all the security?
