Allow users to make

Select this check box to allow UPnP-enabled applications to automatically configure

configuration changes

the ZyWALL so that they can communicate through the ZyWALL, for example by

through UPnP

using NAT Traversal, UPnP applications automatically reserve a SUA/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

Select this check box to create a static LAN to LAN/ZyWALL rule that allows

through firewall

forwarding of ports 1900 and 80. Selecting this check box also creates a dynamic

 

firewall rule every time a SUA/NAT forwarding port is reserved for UPnP. This

 

setting remains active until you disable UPnP or clear this check box.

 

Clear this check box to have the firewall block all UPnP application packets (for

 

example, MSN packets) instead of creating firewall rule that gives them access.
