Minecraft: Enable ports for multiplayer servers - how it works

If you want to play Minecraft in multiplayer mode, you must open the ports for the server. We show you how this works in this guide.

Share ports for multiplayer servers in Minecraft

You can enable the ports both on the router and in the Windows firewall. In this guide we use the firewall. If you are using a FritzBox, you can apply the following instructions to this practical tip.

1. You need a new rule in the firewall to enable the port. To do this, follow the first four steps in this practical tip.
2. Once you have started the wizard to create a new rule, select the "Port" option and click "Next".
3. Decide on "TCP" and enter "25565" as the port.
4. Click "Next" three times, give the rule the name "Minecraft" and confirm the process with the "Finish" button.
5. Now create a second rule. The port is again "25565". Instead of "TCP" choose "UDP".
6. The ports are now released on your PC. Nothing stands in the way of multiplayer in Minecraft.
