Hello. We did that. When we create a game in a different laptop we look for the local IP on that machine. We know there are something gong on that is not allowing us to connect: For example, if we type an incorrect IP it says `connection failed´ right away. But when we type the right local IP it just say `connecting´ After almost a minute or so, it says `Connection failed´ We when are out the LAN, we can create a game, by runing the server archive, and enter our own game by typing our own local IP. But as soon as we are connected to the LAN again, we can´t enter even our own servers. If we can enter under this weird circustances (outside the LAN) we supose is not a version problem, or a firewall thing, but we can´t get it :( This guy seems to had the same problem: http://theindiestone.com/forums/index.php/topic/6122-lan-servers/
