LABEL DESCRIPTION

# This is the index number of the UPnP-created NAT mapping rule entry.
Remote Host 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 UAG 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 UAG forward
inbound packets to the Internal Client from that IP address only.
External Port This field displays the port number that the UAG “listens” on (on the WAN port) for
connection requests destined for the NAT rule’s Internal Port and Internal Client. The
UAG 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 UAG 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 UAG 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.
Internal Client
Type
This field displays the type of the client application on the LAN.
