16.3 Displaying UPnP Port Mapping
Click ADVANCED > UPnP > Ports to display the UPnP Ports screen. Use this screen to
view the NAT port mapping rules that UPnP creates on the ZyXEL Device.
Figure 180 ADVANCED > UPnP > Ports
The following table describes the labels in this screen.
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
ZyXEL Device attempts to use the other WAN port. If the other WAN port
also does not work, the ZyXEL Device drops outgoing packets from UPnP-
enabled applications.
Apply Click Apply to save your changes.

NAT rules in flash
after system
bootup
Select this check box to have the ZyXEL Device retain UPnP created NAT rules
even after restarting. If you use UPnP and you set a port on your computer to be
fixed for a specific service (for example FTP for file transfers), this option allows
the ZyXEL Device to keep a record when your computer uses UPnP to create a
NAT forwarding rule for that service.
WAN Interface in
Use
This field displays through which WAN interface the ZyXEL Device is currently
sending out traffic from UPnP-enabled applications. This field displays None when
UPnP is disabled or neither of the WAN ports has a connection.
The following read-only table displays information about the UPnP-created NAT mapping rule entries in
the ZyXEL Device’s NAT routing table.
# This is the index number of the UPnP-created NAT mapping rule entry.
Remote Host This field displays the source IP address (on the WAN) of inbound IP packets.
Since this is often a wildcard, the field may be blank. When the field is blank, the
ZyXEL Device forwards all traffic sent to the External Port on the WAN interface
to the Internal Client on the Internal Port. When this field displays an external IP
address, the NAT rule has the ZyXEL Device forward inbound packets to the
Internal Client from that IP address only.
