using my own iptables file/rules with SuSEfirewall2

Hi list, I have my own iptables file wich contains all my iptable rules that I have been working on for quite some time. I would like to copy this file to my new SuSE 9.1 box with a few minor changes to some of the rules. I never userd SuSEfirewall2 but it looks like it simply generates all the rules for you This is great but I alreay have my iptables file with all the rules I want. Is there any way to get SuSEfirewall2 to just take my rules and just use them? I really don't want to have to make a startup script that loads all the iptables modules and then reads my rules from file. Maybe someone here has done this already? Any one have any ideas? Thank you Rene
