To restore Windows Firewall rules with netsh.

Open a new elevated command prompt instance.

The syntax for the command looks as follows:

netsh advfirewall import "c:\winaero\firewall_rules_backup.wfw"

Again, you should change the file path portion according to your preferences.

 

The command will produce the following output:

 

 

Files exported and imported using either method are compatible.

This means that you can export your rules using the GUI and restore them using netsh and vice versa.

It is very useful if you want to automate your Firewall rules backup and restore process.
