    Hello,

    To set up the PMG cluster, communication between nodes is better to use in private IP, example 172.16.0.0.0/16 or to use public IP?

    Greetings

    Generally local IPs are preferred for better latency.

    Okay, thank you. Otherwise, in the doc it is stated that PMG uses a VPN link to run the cluster.

    Can you tell me more about it? Is it possible to remove the tunnel on a local network?

    Communication is via ssh tunnel and no, there is no supported way to disable this.

    Just one last question, if I want to change the IP addresses of the nodes in the future. Just modify the cluster.conf file and the hosts file?
