The GUI with Windows Firewall isn't the prettiest & adding multiple rules within the GUI is pretty tiresome ( so why not automate it? ).
A lot of people use custom software firewalls but Windows Firewall is actually pretty good when working on large corporate networks, automating things with Group Policies & Powershell can be fun.
Here are some simple scripts which should help both power users & systems administrators. The main task I found tiresome is adding IP specific blocks, especially when there are multiple IPs involved.
I first made a script to simply block a single IP.
.\fw-block.ps1 add 188.8.131.52
I then expanded on this script, adding the ability to use blocklists.
This script allows you to block based on a blocklist provided. The blocklist should be a text file with IP addresses on each line.
The script syntax is pretty simple & has 3 parameters.
fw-blocklist.ps1 [-Action] <String> -BlockList <String> [-BlockGroup <String>]
BlockGroup is optional, the default group name is "CLI Added IP Blocklist" You should see each rule created in the CLI.
DisplayName : BlockList 184.108.40.206 Description : DisplayGroup : CLI Added IP BlockList Group : CLI Added IP BlockList Enabled : True Profile : Any
Here is how the rules screen should look in the Windows Firewall with Advanced Security view after successfully adding a blocklist.
To remove a blocklist simply use the remove action, this will remove the IP addresses listed within the blocklist you provide.
The scripts can be downloaded from my windows github repo.
