Specifying an IP address and port number

Restrictions and guidelines

If server load balancing is configured, make sure the IP address and port number of the transparent DNS proxy are different than the virtual server of the UDP type.

As a best practice, configure an all-zero IP address for a transparent DNS proxy. In this case, all DNS requests are processed by the transparent DNS proxy.
