Optional Considerations when Setting Up Multiple B Series Appliances in Atlas Clusters
You may optionally configure different hostnames for public traffic and private traffic per cluster node. This means you will need two different hostnames for each node in the cluster, one for the Public Address and one for the Internal Address. All client connections (access console, customer client, presentation client, etc.) will use the public address. All appliance-to-appliance communications (for example, cluster data syncs) will use the internal address. This is useful if you want to keep traffic among B Series Appliances on a different network route than session traffic.
If you plan to use the Network Address Prefixes on the /login > Management > Cluster > Traffic Nodes page, then you must define the networks that this traffic node will serve.
