SuSE 9.0: Which firewall

I am going to install my system new! In the past I used monmotha's firewall script, but since it is not updated since years I am thinking to use another firewall instead. I never used SuSE's firewall, because it was NOT iptables (but now it is) I tried once shorewall, but could not install it with three Ethernet cards (now I need anyway only two) What would you suggest me to use? bye Ronald
