16.4 Installing UPnP in Windows Example
This section shows how to install UPnP in Windows Me and Windows XP.
External Port This field displays the port number that the ZyXEL Device “listens” on (on the WAN
port) for connection requests destined for the NAT rule’s Internal Port and
Internal Client. The ZyXEL Device 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 ZyXEL Device ignores the Internal Port value and
forwards requests on all external port numbers (that are otherwise unmapped) to
the Internal Client.
Protocol This field displays the protocol of the NAT mapping rule (TCP or UDP).
Internal Port This field displays the port number on the Internal Client to which the ZyXEL
Device should forward incoming connection requests.
Internal Client 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.
Enabled This field displays whether or not this UPnP-created NAT mapping rule is turned
on. The UPnP-enabled device that connected to the ZyXEL Device and configured
the UPnP-created NAT mapping rule on the ZyXEL Device determines whether or
not the rule is enabled.
Description This field displays a text explanation of the NAT mapping rule.
Lease Duration This field displays a dynamic port-mapping rule’s time to live (in seconds). It
displays “0” if the port mapping is static.
