Windows 10: Windows 10 firewall won't open/blocks a port

I already added a rule to the firewall with the port I want to be open. I added it as both TCP and UDP. It just doesn't work.

When I disable windows firewall, the port is open. Why is that?


Here's the exact procedure I did.


Opened Windows Defender Firewall with Advanced Security

-> Inbound Rule -> New Rule ->Port -> Specific local port ->Allow connection -> checked all 3 boxes.

Windows 10 Firewall will not open port

Hi Mike,

Thank you for posting in Microsoft Community. I understand your concern and I am glad to assist you.

If Windows Firewall is blocking an application and you want to allow that application to receive info through the firewall, you can usually do that by selecting the application in the list of allowed applications, as described in the previous section.

However, if the application isn't listed, you might need to open a port (a way for applications to receive info through the firewall).

For example, to play a multiplayer game with friends online, you might need to open a port for the game so that the firewall allows the game info to reach your PC. A port stays open all the time, so be sure to close ports that you don't need open any more.

• 
  Open Windows Firewall by swiping in from the right edge of the screen, tapping
  Search (or if you're using a mouse, pointing to the upper-right corner of the screen, moving the mouse pointer down, and then clicking
  Search), entering firewall in the search box, and then tapping or clicking
  Windows Firewall.
  
• 
  Tap or click Advanced settings.
  
  You might be asked for an admin password or to confirm your choice.
  
• 
  In the Windows Firewall with Advanced Security dialogue box, in the left pane, tap or click
  Inbound Rules, then, in the right pane, tap or click New Rule.
  
• 
  Follow the instructions on your screen.

Windows Firewall blocking program even with inbound/outbound rule enabled.

Windows firewall is like a fart when you have squirty dumplings, you shouldn't really trust it.


Disable the private network firewall, if the application works fine do this.

Open a CMD prompt window with admin rights. type in "netstat" without the quotes and press enter. You should get a list of what IP and port is connecting to what port and or service. Open those ports for the application, or just allow those ports to be unfiltered.
