This will test your ability to host multiplayer games of Myth & Marathon by inspecting your computer network's ability to accept connections to your Host.
*Ensure that you have started Marathon, Myth: TFL, Myth II: Soulblighter or Myth III: The Wolf Age and have Hosted a new Multiplayer Game.*
You do not need to be logged into the Mariusnet metaserver to perform this test (e.g. you can host a TCPIP game - just ensure you host it on TCP Port 3453 for Myth, and both TCP & UDP Port 4226 for Marathon).
