Export windows firewall rule

On Windows 10, the Windows Defender Firewall is a security feature that checks incoming and outgoing network traffic and allows or blocks specific traffic depending on predefined rules.

Although every installation of Windows 10 comes with the same set of default rules, you can always create new custom rules to allow or block apps from accessing the network. If you have created multiple firewall rules, and you don’t want to lose you settings after a clean installation, or you want configure other devices with the same policy, you can export and import the Windows Defender Firewall rules using the advanced settings console and Command Prompt.

In this guide, you’ll learn the steps to export the current list of firewall rules as well as the steps to import the rules to a new installation of Windows 10.

Instead of manually configuring the same Windows Firewall rules on many different servers, we can import and export Windows firewall settings to transfer them between different servers.

We can also import the firewall rule policy file into a Group Policy Object (GPO) to apply it automatically throughout a whole domain.

This post is part of our Microsoft 70-744 Securing Windows Server 2016 exam study guide series. For more related posts and information check out our full 70-744 study guide.

Export Windows Firewall Settings

We can export windows firewall rules with both the graphical user interface (GUI) and command line interface (CLI). First we’ll start with the GUI then cover the CLI.

Graphical User Interface

Open Windows Firewall with Advanced Security, right click the top node and select “Export Policy…”

Картинка с сайта: www.rootusers.com

Save the file as a .wfw policy file.

Картинка с сайта: www.rootusers.com

You’ll be advised that the policy successfully exported with a pop up message.

Command Line Interface

This can also be done through the PowerShell or Command Prompt CLI instead with the netsh command, as shown below.

netsh advfirewall export "C:\fw-rules.wfw"

Картинка с сайта: www.rootusers.com

Import Windows Firewall Settings

We can import this file that we have exported to another server where we wish to also have the same set of firewall rules. Again we’ll first start with the GUI solution followed by how to do it in CLI.

Note that importing firewall rules will overwrite all existing firewall configuration and replace it with the exported contents of the .wfw file, you will be advised of this before proceeding in the GUI but not through CLI.

Graphical User Interface

open up Windows Firewall with Advanced Security, right click the top node as before, but this time select “Import Policy…”

Картинка с сайта: www.rootusers.com

You’ll be warned that importing the policy will overwrite all current rules, select yes to proceed.

Next select the .wfw file that was exported previously.

Once the import has completed you’ll be advised by a pop up message.

Command Line Interface

This can also be done through the CLI instead with the netsh command, as shown below.

netsh advfirewall import "C:\fw-rules.wfw"

Картинка с сайта: www.rootusers.com

Note that if you import with the netsh command you will not be warned about overwriting all existing rules like you would be with the GUI.

Summary

As shown we can use either the GUI or CLI to import and export Windows Firewall settings in Windows Server 2016. This allows us to create a set of rules on a single server that we want to deploy elsewhere which is more efficient than implementing the same rules again and again on each server. We can also take this a step further and use group policy to deploy the exported firewall policy files in a domain.
