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.
