Gufw is intended to be an easy, intuitive graphical user interface for managing Uncomplicated Firewall. It supports common tasks such as allowing or blocking pre-configured, common P2P, or individual ports. Gufw has been designed for Ubuntu, but is also available in Debian-based distributions and in Arch Linux; anywhere Python, GTK and UFW are available.
