Basically I have 512k ADSL connection at home which is accessed through network of 3 PC's by a router (Nokia IP55) Problem is some games do not work multiplayer over the net. Doing a local LAN game is fine, but for example with Age of Empires 2 trying to play over the net is a nightmare. Each of the 3 PC's can host a game fine, but none of them are able to join a game being hosted by someone else. Nothing to do with firewalls, I have tried it with them disabled and still nothing. Basically I need any ideas as to what the problem can be. Someone mentioned to me something about port forwarding on the router and how some ports need to be set to open, but I don't have a clue how to do that. Have tired opening all ports on each of the PC's but still same problem. Any help appreciated
