Gufw

Overview

Gufw is a graphical frontend for Ubuntu’s Uncomplicated Firewall (UFW), aimed especially at Linux users who would rather manage firewall rules through a GUI than configure them directly. Its appeal is focused: it puts common rule choices and service presets within reach, but remains tied to UFW and a Linux desktop environment.

Key features

Gufw lets users configure TCP and UDP port rules with Allow, Deny, Reject, and Limit actions. That gives beginners a clearer way to choose how traffic is handled than a bare port entry, while still requiring them to understand which ports and services they intend to expose.

Enabling the firewall sets incoming traffic to Deny and outgoing traffic to Allow by default. This is a sensible starting posture for a desktop system, but the incoming default makes it important to add required access rules before switching the firewall on. In particular, enabling it over SSH without first allowing SSH can sever the remote connection.

UFW’s preconfigured programs and services can simplify adding rules for common software. Gufw 14.10 or newer can also show a Routed option for forwarding rules when IP forwarding is configured. These options extend its usefulness beyond simple local allow-or-block decisions, though routing depends on the underlying system setup.

Gufw 13.10.2 or newer can be used on a remote computer through an exported X display. That is a narrow remote-use route, not a replacement for a web-based administration console. The project is GPL-3.0 licensed.

Pricing

Gufw is free: its Gufw plan costs nothing, with no paid plans or usage limits stated. There is no free trial because the product is already offered as a free plan. This suits individual Linux users and teams seeking a no-cost graphical interface for UFW; there is no paid tier to add broader platform coverage or other capabilities.

Platforms

Gufw supports Linux and is deployed on premises as a frontend for UFW. It can be installed as the gufw package from Ubuntu’s Universe repository. Its Linux focus is a good fit for Ubuntu-oriented setups, but rules out using it as a cross-platform or browser-based firewall manager.

Who it's for

Gufw is best suited to Ubuntu beginners and desktop users who want a graphical way to set basic firewall rules without leaving the UFW ecosystem. Users administering through SSH should prepare an SSH rule before enabling the firewall. Those who need centralized management across vendors, platforms beyond Linux, or a web interface should look elsewhere.

Pros and cons

• Pro: Allow, Deny, Reject, and Limit actions for TCP and UDP rules give users distinct ways to handle traffic without requiring command-line rule entry.
• Pro: Preconfigured programs and services can make common rule creation quicker.
• Pro: The free, GPL-3.0-licensed project has no stated usage limits or paid upgrades.
• Con: Enabling the default incoming-deny policy can cut off SSH access if an SSH rule has not been added first.
• Con: Linux-only support and UFW dependence make Gufw a poor fit for mixed-platform or multi-vendor firewall administration.

Alternatives

For a Linux firewall option that also supports self-hosted and web platforms, consider CacheGuard-OS. Its free plan is indefinite, but setup selects its install capacity and excess capacity can slow or block traffic.

For a free Windows option, TinyWall is a platform alternative; it is open-source and has no ads or paid upgrades.

Comodo Internet Security is another alternative.

Google Cloud Firewall Policies is another alternative.

SonicWall Network Security Manager is another alternative.

Forcepoint Next Generation Firewall is another alternative.

AlgoSec is another alternative.

Check Point DDoS Protector is another alternative.

Verdict

Choose Gufw if you use Linux, especially Ubuntu, and want a free graphical route to managing UFW rules with useful service presets and straightforward traffic actions. Its strongest reason to choose it is that focused, accessible control without a stated usage cap; its main reason to look elsewhere is the narrow platform and management scope, particularly if you need cross-platform administration or must enable a firewall remotely over SSH.
