multicast and iptables
- by Massimo
I have secured a linux box, starting with
iptables -P INPUT DROP
iptables -P OUTPUT DROP
iptables -P FORWARD DROP
and after adding rules to enable specific protocols and streams.
Which are the correct rules to add multicast support ?
I am trying with these - for both client and server multicast :
iptables -A INPUT -m pkttype --pkt-type multicast -j ACCEPT
iptables -A OUTPUT -m pkttype --pkt-type multicast -j ACCEPT
iptables -A INPUT --protocol igmp -j ACCEPT
iptables -A OUTPUT --protocol igmp -j ACCEPT
iptables -A INPUT --dst "224.0.0.0/4" -j ACCEPT
iptables -A OUTPUT --dst "224.0.0.0/4" -j ACCEPT
Linux 2.6.38-12 / iptables 1.4.10
Is there any internet service to test my multicast set ( pc + adsl router + provider ) ?
