To play Hover over the internet you may need to configure your network settings. If you are hosting a game you will need to assign a static IP address to your pc, and if that pc connects to the internet via a router, you will need to forward ports 6500,7777,7778,7787,13000 and 27900 to the IP address of that pc.
An extensive guide of this can be found here: Bit.ly
If you only intend to play Hover over a Local Area Network (LAN), you won't need to perform the above steps. Another way to bypass the need to port forward is to use Hamachi or a similar program.
