ZyXEL Communications P-660R-11V3 User Manual

Chapter 17 Universal Plug-and-Play (UPnP)

P-660R-T1 v3 User’s Guide

When a UPnP device joins a network, it announces its presence with a multicast message. For 
security reasons, the ZyXEL Device 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 the following sections for examples of installing and using UPnP.

Use the following screen to configure the UPnP settings on your ZyXEL Device. Click Access 
Management > UPnP to display the screen shown next.

The following table describes the fields in this screen.

UPnP

Use this field to enable or disable UPnP. Be aware that anyone could 

use a UPnP application to open the web configurator's login screen 

without entering the ZyXEL Device's IP address (although you must still 

enter the password to access the web configurator).

Auto-configured

Use this field to allow or disable UPnP-enabled applications to 

automatically configure the ZyXEL Device so that they can 

communicate through the ZyXEL Device, 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.
