wso2群集防火墙要求

Question

What are firewall requirements for WSO2 cluster?

I have multicast cluster (ELB 2.0.3, AS 5.1.0, ESB 4.7.0) where I have opened all the known ports in our firewall. I have noticed with firewall off, on one of worker node console; when other worker nodes joins/leaves, it announces in the console log. However, same doesn't happens when I enable firewall. I see, it opens random ports in the range 10000 to 99999,i don't know which one to open in the firewall. I wonder if you can give me an explanation about these ports and an idea to what the firewall rules should look like. I would greatly appreciated your assistance.

Thanks, Jahirul

Ok, port range was a red herring. Firewall needed to allow IGMP packets for multicast cluster.
