Prestige 650H/HW

Table 6 UPnP

FIELD DESCRIPTION

Enable the Universal Plug

and Play (UPnP) Service

Select this checkbox to activate UPnP. Be aware that anyone could use a UPnP

application to open the web configurator's login screen without entering the

Prestige'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 Prestige so that they can communicate through the Prestige, 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.
