  • After that, hit the Enter button a few times.
    The commands will add firewall rules to allow incoming connections for Fabric Server, both TCP and UDP protocol

Port forwarding (global friends joining server)

This section describes how to set up port forwarding to allow players from outside your local network to connect to your Minecraft server.

  • If you want to allow players from outside your local network to connect to your Minecraft server, you need to set up port forwarding.
    When someone tries to connect to your router from outside your local network, the router receives the connection request. The incoming connection request specifies a particular port, in this case, Port 25565, which is the default port for Minecraft servers.
  • The router needs to determine where to direct the incoming traffic for Port 25565. The router forwards the incoming connection just as requested, directing it to your computer.
    Once the incoming connection reaches your computer, it establishes a connection with your Minecraft server.

If there are multiple routers between the incoming connection and your computer, the traffic will pass through each router in sequence. Each router along the path will perform its own port forwarding and direct the traffic to the next router until it reaches your computer.

Finally, the traffic reaches your computer, and the player trying to connect from outside your local network is successfully connected to your Minecraft server.

Saving and exiting Fabric 1.20 server

In this section, we will take you through the steps to save and exit Fabric 1.20 server.

  • To save your current progress in the server, you need to input the “save-all” command in the console and hit enter on your keyboard.
    It will save everything in your current world.
  • Type “stop“ and hit enter to close your world.
    While your server is shut down, players won’t be able to connect to play with you.
