IP Passthrough Status
IP Passthrough This displays if IP Passthrough is enabled on the Zyxel Device.
Enable
IP Passthrough allows a LAN computer on the local network of the Zyxel Device to have access
to web services using the public IP address. When IP Passthrough is configured, all traffic is
forwarded to the LAN computer and will not go through NAT.
IP Passthrough This displays the IP Passthrough mode.
Mode
This displays Dynamic and the Zyxel Device will allow traffic to be forwarded to the first LAN
computer requesting an IP address from the Zyxel Device.
This displays Fixed and the Zyxel Device will allow traffic to be forwarded to a specific LAN
computer on the local network of the Zyxel Device.
Cellular Status
Cellular Status This displays the status of the cellular Internet connection.
Data Roaming This displays if data roaming is enabled on the Zyxel Device.
Data roaming is to use your Zyxel Device in an area which is not covered by your service

when you are traveling outside the geographical coverage area of the network to which you
are registered.
Operator This displays the name of the service provider.
PLMN This displays the PLMN (Public Land Mobile Network) number.
GNSS Information
Global Navigation Satellite System (GNSS) sends position and timing data from high orbit artificial satellites. It works
with GPS navigational satellites to provide better receiver accuracy and reliability than just using GPS alone. This is
necessary for 5G networks that require very accurate timing for time and frequency synchronization. With GNSS,
your can easily locate the Zyxel Device with accurate information.
Note: Not all models support the GNSS feature.
