First of all you have to adjust your internet connection.
You have to adjust your port forwarding. Allow port forwarding for the ports 2300-2310 and 47624-47625.
When port forwarding is active one player can host a mp game. The host should look for his ip (there are a lot of internet pages to look for your ip. Look via google search for such a side).
With the ip number the other player can join the game.

There is no other way because of the old net code.
