Well before i could host lan games, and i can still host online games. We're all set to the same workgroup, and my ports have been opened. Any ideas as to what the problem may be?

You can host on internet but not on local net?

Strange problem

Maybe he got a firewall ?

mb he's using the same port?....

This, if you're trying to host with LC or any other program that runs through LAN on wc3 you have to change port, just have start port for wc3 6112 and the end port 6113 , that's all I did and works fine, if you want to host on bnet without LC just change it back 6112-6112
