[CentOS] lokkit

I have used lokkit to setup iptables ( I have a big script that does 
this) basically just ports I want with "--port=https:tcp" etc...

I wish to allow igmp and add igmp to the lokkit command line?

How do I do that?

I can add this to /etc/sysconfig/iptables:

iptables -A RH-Firewall-1-INPUT -i eth1 -j ACCEPT
iptables -A RH-Firewall-1-INPUT -i eth1 -p igmp -j ACCEPT
iptables-save > /etc/sysconfig/iptables

and that works - but I wish my script and the lokkit command to do.

"lokkit --help" goesnt give me anything that I saw.

Thanks,

Jerry
