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 field displays through which WAN port 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.
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.
This field displays the port number that the ZyWALL "listens" on (on the WAN port)
for connection requests destined for the NAT rule's Internal Port and Internal
Client. The ZyWALL forwards incoming packets (from the WAN) with this port
number to the Internal Client on the Internal Port (on the LAN). If the field
displays "0", the ZyWALL ignores the Internal Port value and forwards requests on
all external port numbers (that are otherwise unmapped) to the Internal Client.
This field displays the protocol of the NAT mapping rule (TCP or UDP).
This field displays the port number on the Internal Client to which the ZyWALL
should forward incoming connection requests.
This field displays the DNS host name or IP address of a client on the LAN. Multiple
NAT clients can use a single port simultaneously if the internal client field is set to
255.255.255.255 for UDP mappings.
This field displays whether or not this UPnP-created NAT mapping rule is turned
on. The UPnP-enabled device that connected to the ZyWALL and configured the
UPnP-created NAT mapping rule on the ZyWALL determines whether or not the
rule is enabled.
This field displays a text explanation of the NAT mapping rule.
This field displays a dynamic port-mapping rule's time to live (in seconds). It
displays "0" if the port mapping is static.
