+            Usually it's best practice to have your cluster nodes on private network without firewall for communication among them.
+            Firewall could be enabled just on public access point to your network instead. If for some reason you still need to have firewall
+            enabled on cluster nodes, you will need to open some ports. Default values are UDP port 55200 and multicast port 45688
+            with multicast address 230.0.0.4. Note that you may need more ports opened if you want to enable additional features like diagnostics for your JGroups stack.
+            Keycloak delegates most of the clustering work to Infinispan/JGroups, so consult EAP or JGroups documentation for more info.

         This chapter discusses possible security vulnerabilities Keycloak could have, how Keycloak mitigates those
         vulnerabilities, and what steps you need to do to configure Keycloak to mitigate some vulnerabilities.  A good list
