I use lokkit to set my firewall. on 5.X seems the default is to allow multicast through. on 6.3 seems the default is to block multicast what can I use on the command line for lokkit to enable port 6550 for multicast? Thanks, jerry
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
OKay I did not find a way to enable multicast on the lokkit command line, however, this did work below. The big issue that it did not work the first time was the module was not loaded. modprobe xt_pkttype iptables -I INPUT -m pkttype --pkt-type multicast -j ACCEPT jerry
