3G card.

Device
This displays the manufacturer and model name of your 3G card if you
inserted one in the ZyWALL. Otherwise, it displays none.
Description Enter a description of this interface. It is not used elsewhere. You can
use alphanumeric and ()+/:=?!*#@$_%- characters, and it can be
up to 60 characters long.
Connectivity
Nailed-Up Select this if the connection should always be up. Clear this to have
the ZyWALL to establish the connection only when there is traffic. You
might not nail up the connection if there is little traffic through the
interface or if it costs money to keep the connection available.
Idle timeout This value specifies the time in seconds (0~360) that elapses before
the ZyWALL automatically disconnects from the ISP’s server. Zero
disables the idle timeout.

instructed you to do otherwise).

APN This field is read-only if you selected Device in the profile selection.
Select Custom in the profile selection to be able to manually input
the APN (Access Point Name) provided by your service provider. This
field applies with a GSM or HSDPA 3G card. Enter the APN from your
service provider. Connections with different APNs may provide
different services (such as Internet access or MMS (Multi-Media
Messaging Service)) and charge method.
