For instance, I have a certain "starter script" with iptables rules and other filtering stuff grown over the years. I adapt that, put it on new machines and run it once. Then I save that and only add rules to it from the command line. If I know I want to keep them I save them, otherwise I don't and they will finally go away with the next reboot (e.g. abused mailservers or spambots usually last only for a few days). If there are rules, that I want to keep for longer and/or distribute to other machines I put them in the starter script. Kai
