Chapter 11 UPnP
Basic Home Station VDSL2 P8701T User’s Guide
150
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.
UPnP and ZyXEL

LABEL DESCRIPTION
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).
