Install FirewallD GUI on AlmaLinux 8

This tutorial intends to teach you to install or enable FirewallD GUI (firewall-config) on AlmaLinux 8.

Firewalld is a firewall management solution for many Linux distributions including, Ubuntu, Debian, CentOS, RHEL, and Fedora. It acts as a frontend for the iptables filtering system provided by the Linux kernel. It is protocol independent which means it supports IPv4, IPv6, ethernet bridges, and IP sets.

firewall-config is a graphical tool that can be used instead of the command line to manage your firewall. Normally, this will be installed along with firewalld if you have installed a desktop environment such as Gnome.
