My sons play Minecraft. I recently decided to let them play head to head on the same server. Aside from the financial aspect (I had to buy a second account) it was fairly straightforward running the server. The one thing that tripped me up was a firewall rule that prevented a remote client machine from connecting to the server. Fix was pretty simple.
(2) I set up a rule in Windows Firewall to allow traffic through port 25565, but I still can't see myself when I go to canyouseeme.org unless I disable Windows Firewall. (3) I edited the rules for java.exe to include allowing traffic through port 25565, but I don't think this is the issue, seeing as how I can't even see myself in canyousee.org.

If I was setting up a machine to be a dedicated server, I would want this port to always be opened.
Did that work?
Not yet. So far I’ve only said that the port should be written down to be opened in general. I want this to be persisted.
Now it is open and will be kept open. How: it gets written in to the firewalld config file. If you run
In there you should see a line that contains:
If you decide to disable the server and want to close the port:
What if we want to name this port? We know that the client must look for port 25565 Even if it isn’t in /etc/services. We can name this port “minecraft-server” at least for firewalld purposes. Create this file:
Now, instead of the above commands:
To query:
To Enable:
And to Disable
And use the –permanant flags and –reload if you want to make these changes survive a reboot.
