Table 18-1 Configuring UPnP
FIELD DESCRIPTION
Device Name This identifies the device in UPnP applications.
Enable the Universal Plug
and Play (UPnP) feature 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 ZyWALL'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 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).
Apply Click Apply to save your changes back to the ZyWALL.
