DESCRIPTION
This is the Signal Quality measured in dBm.
This displays the strength of the signal. The signal strength mainly depends on the
antenna output power and the distance between your Zyxel Device and the service
provider's base station.
This shows the name of the company that produced the mobile broadband device.
This field displays the model name of the cellular card.
This shows the software version of the mobile broadband device.
IMEI (International Mobile Equipment Identity) is a 15-digit code in decimal format that
identifies the mobile broadband device.
ESN (Electronic Serial Number) is an 8-digit code in hexadecimal format that identifies
the mobile broadband device.
IMSI (International Mobile Subscriber Identity) is a 15-digit code that identifies the SIM
card.
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 wild-card, the field may be blank.
When the field is blank, the Zyxel Device 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 Zyxel Device forward
inbound packets to the Internal Client from that IP address only.
