EHCache Cluster groups

[Alexander Diedler]

Hello,
I want to set up a 2-node EHCache Cluster for Lucee servers. IF I only setup Distribute type to "automatic" the multicast group port was set to 4446. But only to open this port TCP in a firewall is not enough, the communication was not ok, which additional ports I need to open for communication?

Now I have a test-cluster on 2 servers and a prod-cluster on other 2 servers. How I can avoid, that the EHCache cluster from test-system tries to communicate with the nodes in prod system? Use different multicast-ports?

Best regards
Alexander

You could place them on their own subnet

You could use a firewall to only allow traffic to your test servers 

You could as you suggest, muck with the ports, but that seems difficult.

You could nullhost or null route the production servers
