LABEL DESCRIPTION
UPnP State
UPnP Click this switch to enable or disable UPnP. When the switch goes to the right , the function
is enabled. Otherwise, it is not.
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 Click this switch to allow UPnP-enabled applications to automatically configure the Zyxel Device
so that they can communicate through the Zyxel Device by using NAT traversal. When the
switch goes to the right , the function is enabled. Otherwise, it is not.
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.
The table below displays the NAT port forwarding rules added automatically by UPnP NAT-T.
