Forwarding of multicast packets between two subnets with two NICS - Does not work

WHY DO I NOT GET ANY REPLY FROM A DIFFERENT SUBNET? WHY ARENT
IGMP/MULTICAST PACKETS BEING FORWARDED THROUGH THE LINUX BOX?

Here is my setup:

Linux Box with two NICS
PC1 router NIC(eth0)---NIC(eth1) router
PC2
192.168.1.100 192.168.1.1 192.168.1.111 192.168.4.114 192.168.4.1
192.168.4.100


Linux Box:
---------
/proc/sys/net/ipv4/ip_forward


PC1
----
ping 192.168.4.1 - works
ping 224.0.0.1 - only get reply from 192.168.1.1 and 192.168.1.111


PC2
----
ping 192.168.4.1 - works
ping 224.0.0.1 - only get reply from 192.168.4.1 and 192.168.1.114

Why do you post like an idiot. Turn off the all caps and someone might read
your message.
