firewater is a(nother) hostbased firewall configuration tool. It offers a simple way to compose firewall policies from the command prompt, without the need for a GUI.
firewater lowers the steep learning curve that native firewalling commands have. firewater features user-definable logical groups to keep your policies (or rules) readable and easy to understand. For maximum flexibility, typical firewater statements may be intermixed with native commands to the underlying system-specific firewall.
firewater currently only works with Linux iptables, but is extensible through its modular architecture so that it may support more firewalling systems in the future.
See the documentation for more information.
