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? jerry _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
