This article is about how to host BYOND games. If you already know how to do this but you're having problems (for example, people can't connect to games that you host) then skip down to the Troubleshooting section.

  1. Download the game.
  2. Host the game.


  • Firewalls
  • Port forwarding
    • If asked to choose between TCP and UDP, choose TCP. (BYOND doesn't use UDP. You can forward UDP as well if you like, but it won't make any difference.)
    • "What if this doesn't work?"
      • If you have multiple routers in sequence, you need to set up port forwarding on all of them. Note that some "modems" are also routers.
      • Prefer high-numbered ports; over 2048 is good, over 10000 is better.
