Hi,
Currently we have 2 virtual PMG 9.0.6 nodes in a cluster, each node has 2 nic's, one with a local (192.168.*.*) ip, and one with a public IP. Currently the cluster is configured over the private subnet.
We now want to add a third node to the cluster, but this node is in a different location and has no access to the private ip space.

• Is it possible to just join this node to the cluster using the public IP of the master node, and will this function correctly?
• And if not, is there a way to change the current cluster to use the public network interfaces instead of the private ones?

We eventually created a test cluster to just test the different questions and solutions. What we ended up doing that worked perfectly:

• Made sure all nodes were able to communicate over port 22 and 8006 on the public IP
• updated /etc/hosts and changed the private ip for the node hostname to the public IP
• Changed the private ip to the public ip in /etc/pmg/cluster.conf on both nodes
• Rebooted node 1, and then rebooted node 2 when 1 was back online
• Validated the cluster worked as expected
• add the new node with the public ip
