How to install FirewallD GUI on Rocky Linux 8 | Almalinux 8

Here in this article, we learned the simple steps and commands to install a graphical user interface (GUI) to manage FirewallD on either Alamlinux or Rocky Linux 8. However, the steps are the same for CentOS, Redhat, Oracle Linux, and other RPM-based distros.

FirewallD is a command-line tool to provide a system firewall feature to protect Linux unwanted access by disabling and enabling ports and services access to outside or local networks. However, if you are using a Graphical interface user then the command line may seem a little bit difficult to use. Therefore, to make things easy we can use GUI tools available to manage FirewallD such as one from firewall-config or Plasma firewall
