In this section we have selected ports 80 and 81.

Note that when adding an IP you can also define a specific range.

a) Allow the Connection
b) Allow the Connection if it secure
c) Block The Connection
After selecting the desired option, click Next.
7. In this step, you determine the permission to execute the rule to different networks.
Windows Firewall is divided into 3 different parts:
– Domain: If your system is connected to a domain, it follows these rules.
– Public: Follows this rule if your system is connected to a public network, such as the Internet.
– Private: Follows this rule if your system is connected to an internal network.
Here we have selected all 3 options which means to execute this rule for all 3 firewall modes.
8. In the last step, define a name for your rule and click on Finish.
Note: The rule defined in this tutorial blocks access to ports 80 and 81 for all applications on the system at 5.56.133.29.
