According to your needs, you can configure Windows 8 Firewall settings (block or open port in Windows 7 or Windows 8 firewall) 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 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.

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. Click Next to continue.

At times, you may you may feel the need of opening a port in the Windows firewall to let a specific IP communicate with your computer. For example, while playing games. The procedure to open a port remains more or less the same. All you need to do is follow the instructions in the New Inbound Rule wizard, specify the Port and select Allow the connection.

That’s it!
