configure iptables with NARC

Hello,

I am using iptables and NARC v0.6.3 to setup firewall/router.
Al this is installed on a RedHat 9.0.
I filled in the config files of NARC en ran 'narc start'... and things work!
Great!

But when I restart this box. All config has disappeared and I have to run
NARC again.
Is there a way to run NARC at startup? Or should I add some lines to 'ifup'
or any other network scripts?

Any help is welkom! Take note that I'm quite new to Linux ... but I learn
fast ;-)

Greetz,

Koen
