How To Install Gufw on Debian 12

In this tutorial, we will show you how to install Gufw on Debian 12. Gufw is a graphical user interface (GUI) for managing the Uncomplicated Firewall (UFW) on Linux systems. It simplifies the process of configuring firewall rules, making it accessible to users who may not be comfortable working with command-line tools. With Gufw, you can easily enable or disable the firewall, set default policies for incoming and outgoing traffic, and create custom rules for specific ports, protocols, and applications.

One of the standout features of Gufw is its profile system. Profiles allow you to quickly switch between different sets of firewall rules depending on your location or security needs. Gufw comes with three predefined profiles: Home, Office, and Public. The Home profile is suitable for trusted home networks, allowing essential incoming connections. The Office profile is similar to Home but may permit additional services commonly used in work environments. The Public profile is the most restrictive, blocking all incoming traffic by default, making it ideal for use on public Wi-Fi hotspots or other untrusted networks.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Gufw (graphical user interface for ufw) on Debian 12 (Bookworm).
