Get a Windows or Linux 64-bit machine/VPS with at least 2GB of RAM and a good CPU and internet connection. No Linux desktop is required since the Server can run headless.
Open UDP Ports 5557 and 5558 – Remember to Port Forward on the router and create incoming firewall rules on the server machine. If behind a router, you must Google “Port Forward [Your Router Model]” since each brand is different in how to configure settings.
Allow ICMP Pings / Echo Requests on your router and firewall, else your server ping will always show 1000ms. Again, Google is your friend.
Edit announcements.txt, server_info.txt, settings.json, and groups.json with Notepad to configure server name, playercount, map, permissions, etc.
Run Server.bat and let the server finish loading
If you are trying to play the game on the same machine the server is running on, use the ‘Direct Connect’ button in-game via IP ‘127.0.0.1’ so you can join the server.
