I am adding a line like:
iptables -I INPUT -p udp -m state --state NEW -m multiport --dports 
6550  -j ACCEPT

to /etc/sysconfig/iptables

before the REJECT line...
to allow my multicast port 6550 traffic.

I then restart iptables and it is still not passing through.
If I stop iptables it works.

Am I not defining my line correctly to allow port 6550 udp multicast data?
