[SOLVED] Mod_cluster Manager cant access nodes

Issue

I have installed WildFly10 and started it in domain mode with two servers with port ofsset 100 and 200.

I have configured Apache HTTPD 2.4 and Mod_cluster Manager 1.3.1 with VirtualHost listening on port 8080 and ServerName test-cluster.

When I visit the test-cluster:8080/mod_cluster_manager everything works fine. When I change the listening port in Mod_cluster Manager to 80, restart the Apache and visit test-cluster/mod_cluster_manager I can see the page, but there are no JBoss/WildFly server nodes register...

What could be the problem?

Solution

I found the solution. You need to modify iptables to open broadacast address on which JBoss/WildFly is broadcasting the messages to the cluster.
