Use the Broadband Extend or 3G Extend Wireless Bridge

You can use the WatchGuard Broadband Extend USB or 3G Extend USB wireless bridge to add cellular connectivity to your WatchGuard Firebox T10, XTM 2 Series or 3 Series device. When you connect the external interface of your Firebox to the wireless bridge, computers on your network can connect wirelessly to the Internet through the cellular network.

To connect your Firebox to the cellular network you need:

  • An XTM 2 Series, XTM 3 Series, or Firebox T10 device
  • A Broadband Extend USB (for 4G/3G connectivity) or a 3G Extend USB (for 3G connectivity)
  • A compatible wireless broadband data card

Use the Broadband Extend USB / Cradlepoint CBR450 Device

Follow these steps to use the Broadband Extend Cradlepoint cellular broadband adapter with your Firebox.

  1. Use the instructions in the Cradlepoint CBR450 QSG, available at Cradlepoint CBA450, to set up the Cradlepoint device and update the device firmware.
  2. Configure the external interface on your Firebox to get its address with DHCP. To learn how to configure your external interface, see Configure an External Interface.
  3. Use an Ethernet cable to connect the Cradlepoint device to the external interface of the Firebox.
