Chapter 11 UPnP

Basic Home Station VDSL2 P8802T User’s Guide

When a UPnP device joins a network, it announces its presence with a multicast message. For 
security reasons, the VDSL Router allows multicast messages on the LAN only.

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

ZyXEL has achieved UPnP certification from the Universal Plug and Play Forum UPnP™ 
Implementers Corp. (UIC). ZyXEL's UPnP implementation supports Internet Gateway Device (IGD) 
1.0. 

See 

 for examples of installing and using UPnP.

Use the following screen to enable or disable UPnP on your VDSL Router. Click Advanced Setup > 
UPnP to display the screen shown next.

Network Setting > Home Networking > UPnP

The following table describes the labels in this screen.

This section shows how to install UPnP in Windows Windows XP. 

Click Start and Control Panel. 

Network Setting > Home Networking > UPnP

Enable UPnP

Select this to allow UPnP-enabled applications to automatically configure the VDSL Router 
so that they can communicate through the VDSL Router 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. 

Be aware that anyone could use a UPnP application to open the web configurator's login 
screen without entering the VDSL Router's IP address (although you must still enter the 
password to access the web configurator).
