Did you get a chance to capture network traces from both networks? I 
assume the issue is that the multicast datagrams aren't going through 
the router. If you can "snoop -o <file> multicast" to capture the 
multicast packets on *both* the source and destination network while the 
test runs then we should be able to figure this out quickly.
