Setting up a Multiplayer Server: Difference between revisions

If you want a temporary multiplayer experience it is enough to open a single player world and then in the escape menu click "Open To Lan". This will then allow players in your local network to join. If you want players to join that are outside your local network, you can then also click "Open To Internet" which will attempt to set up that external players can connect to your server. This is done by a technique called UPnP and that has to be enabled on your internet router, which it often is by default. In short, we estimate there's about a 60% success chance that 'Open To Internet' works instantly without issues. If it doesn't you would need to set up a thing called "port forwarding" on your internet router, which can be tricky and frustrating at times, unfortunately.  

For this server to work, your single player world has to stay open

Alternatively the game ships with a dedicated server program that you can start and leave on permanently without needing to log in yourself.
