How to Install/Enable FirewallD GUI on Fedora 36 Linux

FirewallD is software that provides the system firewall feature to protect Fedora users from unwanted access by disabling and enabling ports, services, or protocols. However, for users that are used to an interface such as Graphical User Interface (GUI), then the command line may seem difficult at first glance because there’s no visual representation and who are not comfortable learning the command line terminal to the possibility of having an unsecured system.

However, you can install the FirewallD GUI. This sleek and simple design program is a perfect match for those who want easy access to what’s going on in their system without having too many bells and whistles to distract them from maintaining security.

In the following tutorial, you will learn how to install and enable FirewallD and install FirewallD GUI on Fedora 36 Linux using the command line terminal.

sudo dnf upgrade --refresh

Once you have finished updating and upgrading your packages, install FirewallD.

Install FirewallD

By default, FirewallD should be automatically pre-installed on Fedora 36. To confirm if the firewall is present, use the following command.

sudo firewall-cmd --version

The output should state a version number in the output that shows the presence of FirewallD.

For users that do not have the firewall present, you can run the following command below.
