I remember that someone mentioned a tool on this list which can
generate the differences between two iptables rulesets and build a
script with the necessary insert/delete commands to change a running
firewall with a minimum of iptables calls.

This way the ruleset can be generated on a fast machine and be
transfered to the (often not so fast for a good reason) firewall

Unfortunately I can't find it at the moment.

I'd prefer a Python based solution for this :)
