How to allow apps through firewall on Windows 10

Sometimes the firewall will block trusted apps from accessing the internet, but Windows 10 makes it easy to change the settings to manually allow apps through the firewall — here's how.

Allow app through firewall on Windows 10

Windows 10 comes with several security features to keep your device and data protected against unauthorized access, malware, and other attacks, including a powerful built-in firewall known as Microsoft Defender Firewall.

Although the Microsoft Defender Firewall does a pretty good job managing which applications and features are allowed to connect through the network, sometimes you may need to allow or deny an app manually.

In this guide, you’ll learn the steps to allow or deny app access through the firewall on Windows 10.

    Quick tip: If the app isn’t on the list, click the Allow another app button to locate the application you want to allow.
  6. Check on which type of networks an app can access the network:

    • Private — Allows the app access to the network at home or work.
    • Public — Allows the app access to the network at a public place, such as in a coffee shop.
  7. Click the OK button.

Once you complete the steps, the app will have full access to the network.

If you want to block an app through the firewall, you can follow the instructions outlined above, but on step No. 5, make sure to clear the checkmark for the app or feature you want to deny access to the network.
