Spec score 7.4 #14 of 29 in Firewall Management Software

What it is

Gufw is a free, GPL-3.0 graphical interface for Ubuntu’s Uncomplicated Firewall, or UFW. It lets users configure TCP and UDP port rules with Allow, Deny, Reject and Limit actions. Enabling the firewall sets incoming traffic to Deny and outgoing traffic to Allow by default, while UFW’s preconfigured programs and services simplify rule creation. Gufw is Linux software and an on-premises tool described by Ubuntu documentation as suitable for beginners. Installation uses the gufw package from the Universe repository. Gufw 14.10 or later can show a Routed option for forwarding rules when IP forwarding is configured. Version 13.10.2 or later supports remote use through an exported X display. The Ubuntu guide warns that enabling the firewall over SSH before adding an SSH rule can close the connection. No paid plans or usage limits are stated, and no multi-vendor support is listed.
