What you’ve accomplished

You’ve now updated the instance’s local firewall to open port 25565, then started a client and connected it to the Minecraft server.

Now that your server is running, you can share the IP address with friends for multiplayer play. You can also explore automated startup scripts to ensure the server automatically recovers from reboots.
