I do not remember the name[0], unfortunately, but I vaguely recall reading about a tool that gives you a high-level interface to define firewall rules and than emits a script/config file for various packet filters. It was a long time ago, though, and my memory may trick me. And if that tool really did exist, it might be unmaintained and outdated.
