This is a guide for how to host a multiplayer game on Civilization: Call to Power or Call to Power II using ZeroTier One and IPX Wrapper.
You must follow the guide for players first (which is located below), otherwise you will not be able to see the other players in your lobby. It is a prerequisite for this guide, however you won't be able to join with a network ID yet, since we will need to create one in this guide.
The prerequisite guide is available here: https://gist.github.com/justinfarrelldev/81ea406e08bae1c8b9430a98fbaa47ca.
First, you must set up a ZeroTier network. This is the network that the players will join.
