7.4 UPnP
Universal Plug and Play (UPnP) is an open networking standard that uses TCP/IP for simple peer-to-peer
network connectivity between networking devices or software applications which have UPnP enabled.
A UPnP device can dynamically join a network, obtain an IP address, advertise its services, and learn
about other devices on the network. A device can also leave a network automatically when it is no
longer in use.
See Section 7.6 on page 85 for more information on UPnP.
Use the following screen to configure the UPnP settings on your Zyxel Device. Click Network Setting >
Home Networking > UPnP to display the screen shown next.

LABEL DESCRIPTION
UPnP State
UPnP Select Enable 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).
UPnP NAT-T State
UPnP NAT-T Select Enable to activate UPnP with NAT enabled. UPnP NAT traversal automates the process
of allowing an application to operate through NAT. UPnP network devices can automatically
configure network addressing, announce their presence in the network to other UPnP devices
and enable exchange of simple product and service descriptions.
