Internet users need to use to access a specific service on the NSA.
Note: Some Internet gateways will delete all UPnP mappings after reboot. So if the
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 to the Internet
gateway's WAN port in order to connect to the service on the NSA.
This read-only field identifies a service on the NSA.
Select this check box to have UPnP configure your Internet gateway to allow access from
the Internet to the NSA's service.
If you clear this check box, people will not be able to access the NSA's service from the
Internet unless you manually configure the Internet gateway's firewall and NAT rules to
allow access.
