I would either use or change "/sbin/init.d/firewall" or "/etc/ppp/ip-up". Do you have SuSE 6.2? Have a look at series "sec". There you'll find "fct" a "Firewall Configuration Tool" and "gfcc" a graphical frontend for ipchains firewall rules.
Yes.. it is 6.2 (very nice)
There is a "Handbuch zum Aufbau von LINUX Firewalls V 2.x (GPL)" it's in German but might be usefull. http://www.little-idiot.de/firewall/
Oh.. I was afraid that someone might say that. Is there any way we can get it over to England. I've got a publisher who could translate it. My own German just about get up to "danke" or "ein beer bitter" I was thinking that when the 2.4 kernel comes along it might be an idea to try to publish a small booklet in England which will help the crippled to walk ? Our linux demo days were so much of a success that I've got people crawling all over me who want to do something with linux. So much so that have arranged a linux demo week :-) Thanks for the help :-) Richard Sheffield UK
