Multiplayer Options

From InsideEARTH
=== [Game Ranger] ===
• GameRanger is the most use method for online multiplayer gameplay.
If you do have a troublesome router, you can fix the problem by configuring the router to enable Universal Plug and Play (UPnP), or manually do port forwarding for UDP port 16000.

=== [EarthNet/MoonNet] - CURRENTLY BROKEN! ===
• EathNet/MoonNet is still used by some but predominantly most use GameRanger due its simplified use and the need to not forward ports on most recent routers.
