Creating a USB/Ethernet interface (for USB sticks /modems)

USB/Ethernet interfaces are created and used in remote connections through a modem directly connected to the firewall (USB port).

A USB/Ethernet interface is automatically created whenever a HUAWEI 4G USB modem that supports the HiLink feature is connected to the firewall and then configured.

If this is not the case, a modem profile must be configured in order to create a USB/Ethernet interface associated with the USB stick/modem. You can define two modem profiles on the firewall but only one USB/Ethernet interface can be added to the firewall.

Creating a modem profile

  1. Click on the Editmenu.
  2. Click on Modem profiles and select one of the modem profiles (named Modem 1 and Modem 2 by default).
    The control panel of the modem profile appears.

Initialization string no. 1 This string is optional and allows sending "AT" configuration commands to the modem before it is used. Example: "ATZ" (command to reinitialize the modem), "AT^CURC=0" (command which allows periodic messages to be disabled).
Initialization string no. 2 This string is optional and allows sending "AT" configuration commands to the modem before it is used. Example: "ATZ" (command to reinitialize the modem), "AT^CURC=0" (command which allows periodic messages to be disabled).
