I don't think this is a bug, as each member does receive their own messages. However, the *peer* members don't receive messages !

Not picking a NIC leads to issues in the ATL labs (at least clusterxx.qa.atl.jboss.com): you *have* to use the virtual NICs assigned to you (e.g. MYTESTIP_1), otherwise the members won't see each other.

In addition, you also have to pick the 'right' IP multicast address, in order to send your traffic to the correct switch/router (MB, GB).

I don't know if this changed recently. If not, maybe we should ask the IT folks to assign a *reserved* NIC for Hudson's test runs and possibly a routing entry for a specific multicast address...
