[ILUG] Adding custom rules to the SuSE 9.2 firewall

[Paul Gargan]

Hi list,

I'm running SuSE 9.2 professional and have enabled the built-in 
firewall. It's just a wrapper to iptables but I'd like to stick with it 
for the moment.

I need to add a custom rule to allow multicast traffic, i.e. something like:

	iptables -I input_ext 2 -d 224.0.0.0/24 -p udp -j ACCEPT

The "input_ext" is a chain through which all incoming traffic for eth0 
is filtered.

This works, but I'm looking for a way to make it persist across boots. 
The SuSE firewall tool won't allow adding such a rule through the GUI, 
so I'm looking at adding that line to some boot script or other, e.g. 
like in RH9's /etc/rc.d/rc.local

SuSE 9.2 doesn't have an rc.local file. So where's the recommended place 
to put stuff like this? I'd prefer not to go editing the firewall shell 
scripts directly.

Thanks,
Paul.
