Windows 10: Microsoft Defender firewall list of allowed apps and functions

Hello all

My game League of Legends, it is not on the Microsoft Defender firewall list of allowed apps and functions, and yet I can play it. All my other games is on the list. This is the case on both my laptop and main PC.

How can this be?
Have I somehow granted it access in some other way?

Thanks in advance for replying

Best regards

:)

 

Defender Firewall will not save "allowed app" rules

I am having a persistent, ongoing problem with allowing apps through Windows Defender Firewall (Windows 10 Pro 1809). Basically, the firewall is not remembering when I add an app to the list.

From the control panel I am going to "Allow apps to communicate through Windows Defender Firewall". One of the apps in question is already listed and I need to continually enable it through the Public connection. But the rule doesn't stick.

Another app is missing from the list so I manually add it, and things work fine for that session. If I restart the system and go back to these rules, the manually added app is no longer in the list, and the already present app in the list has again reverted to Private only. I have to constantly reset these.

Why won't these apps stick in the allowed apps, and how do I fix it?

 

Windows Defender Firewall - Previously allowed APP disappears

I'm having an issue with Defender firewall. I manually allow an app through the firewall on both public and private networks. The app works fine. When I restart the computer the approved app is no longer listed and the app does not work properly.

What I'm trying to do is use Teamviewer to remotely control an Intel NUC via the NUC IP address on a local area network. If I add Teamviewer to the list of apps through the firewall it works fine, but upon restart I cannot login to the NUC with Teamviewer and upon investigation the app is missing from the firewall approved apps.

This is with Windows 1809.

I have a second NUC running Windows 1803 and it does not have this problem.

Any thoughts?

 

Allow app through firewall

Hi Natasha

Click your Start Button and just type firewall

From the resulting list, choose 'Windows Defender Firewall'

That will open the Firewall section of the old Control Panel

On the left, click 'Allow an app or feature through Windows Defender Firewall' to begin the process . . .
