This should work. Your linux boxes won't route multicast without the
entry in the routing table. I found this out while trying to debug
clustering with jboss and it fixed all my issues. Also make sure any
routers on your network will route multicast.

Since you are on RedHat you have to do these steps to enable multicast
on your machines:
assign an IP to a host
ifconfig eth0 multicast
route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0

Hi Filip,
are you running iptables firewall?
no. The servers are inside a hardware firewall.
that might also be blocking your multicast.
I do suggest you get a little utility that tests your multicast.
Can you suggest one?

Simon
