Media Server User’s Guide

You can use UPnP port mapping to allow access to the NSA’s management screens. If you use UPnP 
to allow web configurator access from the WAN, you may want to use a different WAN port number 
(instead of the default of port 80) to make it more secure. Remember to use the custom port 
number when accessing the NSA’s web configurator from the Internet.

This is the NSA’s web publishing feature that lets people access files using a web browser without 
having to log into the Home screens. Use UPnP port mapping to allow access to these files from the 
Internet without having to enter a user name or password. See 

on web publishing.

Click Network > UPnP > Port Mapping to display the UPnP Port Mapping screen. 

Use this screen to set how the Internet gateway’s UPnP feature configure’s the Internet gateway’s 
NAT IP address mapping and port mapping settings. These settings allow Internet users connected 
to the Internet gateway’s WAN interface to access services on the NSA. You can set which port 
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.
