Chapter 14 Universal Plug-and-Play (UPnP)

NBG-418N User’s Guide

All UPnP-enabled devices may communicate freely with each other without additional configuration. 
Disable UPnP if this is not your intention. 

Use this screen to enable UPnP. Click the Management > UPnP to open the following screen.

Management > UPnP > General 

The following table describes the labels in this screen. 

This section shows you how to use the UPnP feature in Windows XP. You must already have UPnP 
installed in Windows XP and UPnP activated on the NBG-418N.

Make sure the computer is connected to a LAN port of the NBG-418N. Turn on your computer and 
the NBG-418N. 

Click start and Control Panel. Double-click Network Connections. An icon displays under 
Internet Gateway.

Management > UPnP > General

Enable the Universal Plug 
and Play (UPnP) Feature

Select this check box to activate UPnP. Be aware that anyone could use a UPnP 
application to open the Web Configurator's login screen without entering the 
NBG-418N's IP address (although you must still enter the password to access 
the Web Configurator).

Allow users to make port 
forwarding changes through 
UPnP

Select this check box to allow UPnP-enabled applications to automatically 
configure the NBG-418N so that they can communicate through the NBG-418N, 
for example, by using NAT traversal. UPnP applications automatically reserve a 
NAT forwarding port in order to communicate with another UPnP enabled 
device. this eliminates the need to manually configure port forwarding for the 
UPnP enabled application. 

Apply

Click Apply to save the setting to the NBG-418N.

Reset

Click Reset to begin configuring this screen afresh.
