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.

NAT rules in flash
after system
bootup
Select this check box to have the ZyWALL 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
ZyWALL 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 ZyWALL 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 ZyWALL’s NAT routing table.
# This is the index number of the UPnP-created NAT mapping rule entry.
