verify packets actually land on the receiver (tcpdump, etc) interface. verify that your host has a route for 224/4 pointing out the interface you hope joins are leaving from. ensure iptables isn't blocking either the outgoing igmp join, and make sure that it's permitting the incoming mcast-dest packets.
if any of these are wrong/failing, then mcast won't work.
