In my latest attempts, I've cleared all iptables rules to be sure that wasn't an issue. There is no other firewall between these boxes. I will pursue the possibility of no multicast support, although our network engineers have told me it is enabled on our switches. > > 2. Using the GUI, the other node never shows online.

I've captured some packets using tcpdump, and indeed, I never see the multicast traffic being received, only sent. The odd thing is that these machines respond to other multicast traffic, like pinging 224.0.0.1. Is there a kernel option that anyone is aware of that could be causing the boxes to drop multicast?
