When NAT is enabled, you can display details about a specific connection. 

To display the connection details, type “D” on the NAT Configuration 

menu and enter the public IP address. The IAD prompts you for the outside 

port number of the connection.

Type the outside port number and press Enter. The IAD displays the NAT 

connection details. The IAD will advise you if there are no connections 

open. 

Press any key to return to the NAT Configuration menu.
