Prestige 650H-E
Table 9 UPnP
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).
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.
This field is not available on all models.
Select this check box to allow traffic from UPnP-enabled applications to bypass
the firewall.
Clear this check box to have the firewall block all UPnP application packets (for
example, MSN packets).
