Configure an LTE Modem

You can connect a Firebox T80 to a 4G LTE cellular network with an LTE interface module. This enables you to install a SIM card and use the cellular connection as an external interface on the Firebox for primary or backup WAN connectivity.

LTE and 4G wireless networks offer multi-gigabit per second (Gbps) connectivity that can exceed the performance of most traditional wired Internet connections. The LTE modem can switch to 3G if 4G communication is not available.

The LTE modem supports the same Firebox features as 3G/4G USB modems. For more information on modems and the Firebox features they support, see About Modem Interfaces.

LTE Configuration

To use an LTE cellular connection with a Firebox:

  • On the Firebox T80, you can install an LTE interface module that enables you to insert a Micro SIM card or Nano SIM card (with an adapter) into the module to activate a 4G LTE connection on the Firebox.
  • You can only enable one modem as an external interface. You cannot use an external modem at the same time as the LTE interface module.
  • On the Firebox T80 with an LTE interface module, you must reconfigure an external modem if you switch between the LTE interface module and an external modem that you have plugged in to the Firebox. Only one modem can be in use at any time.

Verizon is currently not yet supported for 4G LTE access for the Firebox T80 LTE module.

Access Point Name (APN)

To establish a connection for an LTE modem, some wireless service providers require an Access Point Name (APN). In many cases an APN is required if the LTE service is a business class connection. To determine the requirements to configure your LTE modem, verify with your provider if an Access Point Name (APN) is required to connect.

In most cases, you do not have to specify the APN because the APN is automatically assigned by your service provider when the connection is established.

SIM Card Lock PIN

Some cellular providers lock their SIM card with a PIN to prevent unauthorized use. If the SIM card is locked, you can specify the PIN to unlock the SIM card. If you do not know your PIN, contact your provider for information on how to disable or unlock the SIM card. Do not attempt to guess the PIN because too many incorrect entries can lock and disable the SIM card.

To specify a PIN for a locked SIM card:

  • From Fireware Web UI, select System Status > 4G LTE Modem, then click Unlock SIM Card.
  • From Fireware System Manager, select Tools > Unlock SIM Card, or from the Front Panel tab, right-click LTE Status in the Interfaces section for modem0, then select Unlock SIM Card.

After you specify a correct PIN, the Firebox unlocks the SIM card and disables the PIN permanently. The PIN is not required again even if the Firebox is rebooted or restored to factory default settings because the action is performed on the SIM card.

Monitor the LTE Modem

To see details and statistics about your 4G LTE modem:

  • From Fireware Web UI, select System Status > 4G LTE Modem.
    For more information, see 4G LTE Modem Status. The 4G LTE modem status also appears on the Dashboard Front Panel in Fireware Web UI.
  • From Firebox System Manager, select the Front Panel tab and view the Interfaces section for modem0. For more information on the Firebox System Manger Front Panel, see Basic Device and Network Status (Front Panel).

Link Monitor

To prevent unwanted bandwidth consumption, link monitor is not enabled for modem interfaces by default. For more information about link monitor, see About Link Monitor.

To configure link monitor targets for modem interfaces:

  • From the Web UI, select Network > Link Monitor.
  • From Policy Manager, select Network > Configuration > Link Monitor.
