It worked fine before, but now for some reason the games just won't Join a LAN game. I'm running Leopard 10.5.2 and I have installed the latest patches for both games (1.0.3 for AoEIII and 2.0.1 for AoM). It's possibly worth noting that GameRanger says I'm "behind a Port-Restricted Cone NAT Router" (although GR is online and I just want to play LAN). In Age of Empires III, it simply says "Failed to Join Game" and in Age of Mythology, there's a countdown screen that says something similair when the countdown is completed. I'm puzzled. I've tried every possible setting in System Preferences and on my AirPort Extreme, nothing works. Is this a common problem? Anyone know what I can do?
