If you're interested, I've written a small tool as a proof of concept and 
prototyped it in Bash. It's called Dwall and allows you to set up complex 
firewalls (ie. with multiple zones) using only a few config-files.

It's actually very simple and allows you to have an overview of what is 
configured and what changes have been made and when (and by whom). You can 
download it from:


I'm looking for someone who's got the time to re-implement it in Python, 
but if that doesn't happen and I gain some extra time, I may do that 
myself :)
