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

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.

**Table 1** High-risk ports
Protocol	Port
TCP	135, 136, 137, 138, 139, 445, 3333, 4444, 5554, 6000, 8090, 9995, 9996, 25000, 50050, 53413, 60000
UDP class	135, 137, 138, 139, 593, 901, 1027, 1028, 1068, 2745, 3127, 3128, 3333, 5800, 5900, 6000, 6129, 6667, 8090, 8998, 9996, 25000, 50050, 53413, 60000

You are advised to change the port.
