About this video: If you want to add Java to your Windows Defender firewall for a Minecraft server, this is the video for you! We show you exactly how to make an exception in Windows Defender for Java and Minecraft. By doing this, you will be able to let people join your server through your public IP address. Thus, without any more delay, here is how to allow Java in Windows Defender.

The first step is to open up your Windows Control Panel. After that, click on ‘Windows Defender Firewall’. That will open up your firewall settings. From here, you actually need to select ‘Advanced Settings’. This is where we will be able to see all of the firewall rules in Windows Defender. There are going to be tons of different rules here for pretty much everything that connects to your computer.

When it comes to Minecraft though, we are going to be focusing on inbound rules as we are looking for people to make an inbound connection to your computer for your Minecraft server. When you click on inbound runes, find all of the mentions of ‘Java’ and Minecraft, and enable. You want to make sure that all of these are enabled and allowing public and private connections in order to get your server where people can join it.

If you don’t see Java or Minecraft listed anywhere, you will need to add it manually. To do this, click on ‘New Rule…’, select ‘Program’, and then, click ‘Browse…’. After that, navigate to your local disk, find Java, Java Version, bin, and then select ‘java.exe’. You will need to repeat this for the ‘javaw.exe’ program again.

Oddly enough, you don’t need to select ‘Minecraft’ in order to allow people to join your server. You just need to select Java. Minecraft is to do with you joining people’s servers in Minecraft.

After that, you can start your server, and your friends will be able to join assuming that your port forward is correct. If they can’t there is most likely an issue with your port forward or an issue with a firewall on your router.

  1. I let Java through my fire wall and did as the tutorial asked, but Minecraft still dose not have connection. Does anyone have an idea what else could be preventing Minecraft from having connection other than no Wi-Fi?

  2. So what if instead of not having java rules I don't have minecraft rules (I do own the game minecraft though) and he has like 50 java rules I only had 2…

  3. Did literally everything in this video, and it still did not work. I check if my both my local and public IP were static and both were. My server used to work and now something in Windows is preventing it from working ever since I updated windows.

  4. i di everything correct and =me or my frinds cant join the server it just says conecting to server and then connection timed out no further information or something like that, i port forwarded, did the eula, server properties, and everything else thebnn did it teice more and we still cant join?
