No, yes.
I usually create an /etc/init.d/firewall for this purpose which I link
to from /etc/rc2.d/S25firewall and /etc/rc0.d/K15firewall.
A simple version contains something like this:
set -x
case $1 in
start|restart|reload)
echo Establishing firewall.
;;
stop)
echo Removing firewall.
;;
*)
echo Usage: $0 '{start|stop}'
exit 1
;;
esac
### Flush rules and delete custom chains
iptables -F
# iptables -X customchain1 2>/dev/null
# iptables -X customchain2 2>/dev/null
[ $1 = stop ] && exit 0
### Create custom chains and rules below
...
Cheers,
Emile.
