18.5 Installing UPnP in Windows Example
This section shows how to install UPnP in Windows Me and Windows XP.
UPnP
Table 18-2 UPnP Ports
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.
