Now you want to permit for traffic to are available through port 25565, which is the default port that Minecraft uses to allow connections. In some circumstances ufw will use named traffic rules, such as for ssh, which at all times makes use of port 22 by default, but in less common circumstances like this one, we’ll specify the port number manually. Add the required firewall rule by working the following command:
