    • To add a new edge service, click Add. In the Add Edge Serverdialog box, in FQDN, type the FQDN of the service that you want to add. If you are using an array of Access Edge services, specify the FQDN of the virtual IP address of the internal load balancer.

    • To remove an edge service from the list, click the name of the service, and then click Remove.

    • To add a new edge service, click Add. In the Add A/V Edge Serverdialog box, in Internal FQDN, type the FQDN used for access from the internal network.
