A firewall is a significant aspect of computing. You can open firewall ports in Windows 10. It is an important security feature for any PC that works alongside antivirus software. Firewalls are there to protect you from threats on the internet and shield your computer from hackers. The threats may be incoming or outgoing.

That is either the threats from the outside trying to get in or threats from the inside trying to get out.

Let’s begin!


A firewall is installed in almost all windows computers so that your computer remains safe and secure. It checks the programs that want to connect to your computer’s network system. Firewall will block the program if it was not enabled to pass.

It checks its database of rules to see if it is allowed or not. If it doesn’t know, it asks you, which is why you sometimes see prompts asking you if a particular program is permitted to access the internet.

Here are some simple steps to open a Firewall port in Windows 10.

Steps to Open Firewall Ports in Windows 10

  • Step 1: Go to the windows search box, click and type Windows Defender Firewall and open the top results.
  • Step 2: Now click the advance setting link which appears on the left side of the panel and to any admin prompts, press yes.
  • Step 3: Click the Inbound Rules which appear on the left frame of the window. Adding this rule will allow you to control the traffic.
  • Step 4: Press the new rule option which is situated on the right pane.
  • Step 5: Select the port you need to open and click ‘Next’.
  • Step 6: There are two options, press either TCP or UDP.
  • Step 7: Add the port number and click ‘Next’. To add a range of ports to your Windows firewall rule you can simply separate different ports by a comma, or add a   “-” between two numbers.
  • Step 8: Select allows the connection and hit ‘Next’. You can also block the port by simply clicking on the ‘Block the connection’. By this, you can choose what you want the window firewall rule to do.
  • Step 9: Now select any network type and again click ‘Next’. You may apply the rule outside of your home network as this rule is not network-specific. Select Domain to apply the rule when the computer is connected to its corporate domain, Private rule applies when a computer is connected to a private network such as at home and the Public rule is used for the shared network.
  • Step 10: At last, give a relevant name and click ‘Finish’.

That is how the firewall windows are ready to be opened.
