Why Can't I Specify Certain Ports When Configuring the Forwarding Rule?

Symptoms

When I set the forwarding port and origin server port to specific ports, the configuration of the forwarding rule fails.

Port range: 1 to 65535

AAD regards the ports in Table 1 as high-risk ports and cannot be used.
