Can I create a cluster using a different interface than the primary controller IP

  • 1.  Can I create a cluster using a different interface than the primary controller IP

    Here it the scenario I am trying to work through.

    AOS 8.5.0.4

    Redundant Mobility Masters

    Redundant controllers in a Datacenter(DC)

    Controller IP address is in the internal VLAN

    There is an additional interface connecting to a DMZ

     

    The redundant DC controllers are intended as an AP failover for sites with a single controller as well as RAP connectivity. When attempting to create a cluster I am only able to specify the controller IP and not my DMZ interface IP. Inside the cluster configuration is where the NAT mapping is done from controller IP to public RAP IP. Due to security rules we can not NAT to the internal IP of the controller to the public IP. The NAT will only be allowed to the DMZ interface. Is there any way to get around this, either by creating the cluster using the DMZ intereface, or mapping the NAT IP to the DMZ interface some how? My backup option is to not cluster these two controllers. If that is my only option, what would that configuration look like. Anyone have info on how to configure that properly?

    Then, don't create a cluster.  Just have an individual controller.

    To answer your question, you cannot use a different interface. I hope
