How to open ports in Windows Firewall

According to your needs, you can configure Windows Firewall settings (block or open port in Windows 10/8/7l) and restore defaults if you are unsatisfied with the default Windows Firewall settings. However, for this, you need to get to the advanced settings of the firewall. This is simple, simply open up the control panel and in its search box type – Firewall. Then open Firewall and click on its ‘Advanced Settings’ link.

In this post, we will see in detail how to block or open a port in Windows 10/8/7/server 2012/server 2016 firewall.

Doing so will open the ‘New Inbound Rule Wizard’ window.

From it, select ‘Port’ as the new Rule Type and click Next. For safety purposes, I tried blocking TCP port. Click on Specific local ports. Then choose one port like 80 as shown in the screenshot below.

Later, select all the profiles available for different type of connections (Domain, Private and Public) and Click Next to continue.


Give a name of your choice to the new rule. I used ‘block suspicious ports’. If you want, you can add the description to the new rule. This step is however optional.
