DESCRIPTION
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).
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.
Click Apply to save your changes back to the ZyWALL.
Click Reset to begin configuring this screen afresh.
DESCRIPTION
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.
This is the index number of the UPnP-created NAT mapping rule entry.
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
ZyWALL 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 ZyWALL forward inbound packets to the Internal
Client from that IP address only.
