DESCRIPTION
This displays the name of your network service provider. This shows Limited Service if
the service provider has stopped service to the mobile broadband card. For example if
the bill has not been paid or the account has expired.
This field displays what type of cellular network the mobile broadband connection is
using. The network type varies depending on the mobile broadband card you inserted
and could be UMTS, UMTS/HSDPA, GPRS or EDGE when you insert a GSM mobile
broadband card, or 1xRTT, EVDO Rev.0 or EVDO Rev.A when you insert a CDMA
mobile broadband card.
This displays the strength of the signal. The signal strength mainly depends on the
antenna output power and the distance between your USG and the service provider's
base station.
DESCRIPTION
Select an entry and click this button to remove it from the list.
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 USG 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 USG forward
inbound packets to the Internal Client from that IP address only.
This field displays the port number that the USG "listens" on (on the WAN port) for
connection requests destined for the NAT rule's Internal Port and Internal Client. The
USG 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 USG 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).
