After you finish port forwarding your router, you can invite other players to play using your server. For this step, you’ll need the IP address you just got from Google.
To start, open Minecraft and choose Multiplayer from the main menu. Then, click Add server, and enter your server name. Afterward, you’ll need to enter your server address, which is the external IP address followed by the port number.
If your external IP address is IPv6, you’ll need to surround your address by [ ], then provide the port number.
After that, click on Done, and Minecraft will connect to your server. When the connection is established, click on the server name, and click on Join Server.
To invite your friends to play, you’ll need to give them your external IP address. That’s why you need to make sure you trust the invited players. If you’re a parent, make sure to check the friends your kid is inviting to play with because the server will be open to the public.
