access a specific service on the NSA.

Internet gateway reboots, you may need to use this screen again to re-apply the
UPnP port mapping.

DESCRIPTION
Use these fields to specify what port the Internet gateway uses to
connect from its LAN port to the service on the NSA.
This read-only field identifies a service on the NSA.
Specify the port number (1~65,536) the Internet gateway needs to use
to connect from its LAN port to the service on the NSA. This is the NSA's
internal port number for the service. Changing a service's port number
in this screen also changes it in other NSA screens that display it.
Similarly, changing a service's port number in another NSA screen also
changes it here.
The number below this icon is your Internet gateway's WAN IP address
(the IP address your Internet gateway uses for connecting to the
Internet).
Use these fields to specify what port Internet users must use to connect
