• Mason - the automated firewall builder for Linux
  By William Stearns and Jeff Licquia. Mason is released under the GNU GPL.
  Mason is a tool that interactively builds a firewall using Linux' ipfwadm or ipchains firewalling. You leave mason running on the firewall machine while you are making all the kinds of connections that you want the firewall to support (and want it to block). Mason gives you a list of firewall rules that exactly allow and block those connections.
  Mason was specifically designed to make it possible for anyone with the ability to generally find their way around a Linux system to build a reasonably good packet filtering firewall for any and every system under their control.

• Firewall Builder
  Firewall Builder consiste em uma interface gráfica (IGU/GUI) orientada a objetos e um conjunto de compiladores de política para os populares mecanismos firewall código-aberto: iptables, ipfilter e OpenBSD PF. Uma política de firewall é um conjunto de regras; cada regra consiste em objetos abstratos que representam entidades e serviços da rede real (hosts, routeadores, firewalls, redes, protocolos). Firewall Builder ajuda administradores a manter uma base de dados de objetos e permite a edição de políticas usando operações simples de arrastar-e-soltar. Preferências e banco de dados de objetos são armazenados em formato XML. A IGU é escrita usando o toolkit GTK e pode ser usada tanto em sistemas Gnome quanto KDE. Firewall Builder é parte de várias distribuições Linux.
