Nova has been down all this week. Fortunately the gaming is not tied entirely to Nova. In tough times like this it is possible to get a good game via BattleLan. This little LAN utility is a little iffy. Sometimes it works, and sometimes it does not. Why this is I do not know. I am gratified when it does.
Here is a video where they are using BattleLAN to play Need For Speed.
You will notice the tutorial mentions both host and player IP are input into BattleLAN.
