Hello.
I've installed Europa Universalis 2 and Trackmania Nations Forever. Games look cool :) , but I can't open LAN game mode in both games. In Europa the Internet mode also is down. In the LAN mode I set custom IP: me (Ubuntu 10.04) - 10.0.0.2 and another computer (Windows XP) - 10.0.0.3. On the computer with Windows the game works perfectly, but I can't host game and join another game :sad: .
Can somebody tell me how to repair the problem?
