iptables init setup

Forgive me if this is covered elsewhere, just point me in the correct
direction.

I have installed SuSE 7.3 kernel 2.4.19 on a SS5, all is fine. I would
like to manage my firewall with iptables and I have confirmed they work
properly. What I did not find was a rc.d script for managing the
firewall, obviously I can script my own and run from rc.local, etc...,
but perhaps there is a more integrated approach which will run as part
of the network setup.

Did I miss it?

Many thanks for your suggestions.

Michael
