I'm confused. You say, "looks like UDP is allowed," and then you say, "it looks like the 231.7.7.7 would not be able to send." Then you attached some screen shots of what looks like some kind of administration console that I don't recognize. So is UDP multicast supported in your cloud environment or not? A simple yes or no will suffice.
At this point I'm not sure I can provide the kind of help you need so I'll just say a few things in the hope that they'll be productive: 1) Most cloud environments don't support UDP multicast so configuring your cluster to use UDP multicast in a cloud environment is likely to result in a broken cluster. 2) If your cloud environment doesn't support UDP multicast then you can either use static clustering or JGroups. You can see examples of these configuration in the "clustered-static-discovery" and "clustered-jgroups" examples respectively.
