Note:
For hardware load balancer, the IP addresses that are assigned to the actual external network interfaces of the Edge Server may depend on which hardware load balancer you choose. Refer to the documentation for your hardware load balancer to understand the actual IP address requirements.
For DNS load balancing with private IP addresses using NAT, in topology builder, input the private IP addresses to the external edge services for each edge server and input the public IP addresseses of external a/v edge service to “NAT-enabled public IP address” under A/V edge service for each edge server.
