The following table describes the fields in this screen. 

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. 

 

Allow UPnP to pass through 
Firewall 

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).
