Allow users to make 

configuration 

changes through 

UPnP

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

configure the ZyWALL so that they can communicate through the ZyWALL, 

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).

Outgoing WAN 

Interface

Select through which WAN port you want to send out traffic from UPnP-

enabled applications. If the WAN port you select loses its connection, the 

ZyWALL attempts to use the other WAN port. If the other WAN port also 

does not work, the ZyWALL drops outgoing packets from UPnP-enabled 

applications.

Apply

Click Apply to save your changes back to the ZyWALL.

Reset

Click Reset to begin configuring this screen afresh.
