P-2802H(W)(L)-I Series 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.

Table 112   Configuring UPnP

Active 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 ZyXEL Device's IP address (although you must still enter 

the password to access the web configurator).

Allow users to make 

configuration changes 

through UPnP

Select this check box to allow 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.
