USB/Ethernet interface (for USB key/modem)
USB/Ethernet interfaces are used in remote connections when your modem is directly connected to the firewall’s USB port. You can add only one USB/Modem interface on your firewall.
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 you are using another USB modem, a modem profile must be configured before a USB/Ethernet interface can be created.
NOTE
If your modem must be plugged into the firewall's Ethernet port or serial port (PPPoE/PPTP modem), refer to PPPoE/PPTP modem interface.
Modem profile control panel
Click on Edit > Modem profiles to open the control panel of a modem profile. Two modem profiles can be defined; select one of them.
Status
ON / OFF | Set the switch to ON / OFF to enable/disable the modem profile. |
General settings
Name | Enter a name for the modem profile. |
Model | Enter the model of the modem for which the profile is being created (open text field). |
Vendor ID | ID specific to each modem vendor (Vendorid or VID). This is a hexadecimal string. |
Initial product ID | Product ID (Productidinit) after it has been recognized as a USB storage device. This parameter is specific to each modem model. |
Target product ID | ID representing the product when it is in modem mode (ProductId or PID). This parameter is specific to each modem model. |
MessageContent for modem mode | This is a character string that allows the firewall to detect the USB device connected as a modem (ModeSwitchString). |
Advanced configuration
Configuration command port | This is the number of the dedicated serial port for sending configuration commands ("AT" commands) to the modem. The most common value is 0. |
Monitoring command port | This is the number of the dedicated serial port for sending monitoring commands ("AT" commands) to the modem. The most common value is 1. |
Initialization string no. 1, 2 and 3 |
These strings are optional and allow you to send "AT" configuration commands to the modem before it is used. EXAMPLES

Configuring profiles | When no modem profiles are defined or active, a message will prompt you to configure a modem profile. For further information, refer to the section Modem profile control panel |
General settings
Name | Name of the interface. Cannot be changed. |
Comments | Allows you to enter comments regarding the interface. |

An interface can be:
|
Address range
Dynamic IP (obtained by DHCP) |
When this option is selected, the IP address of the interface will be defined by DHCP. An Advanced DHCP properties zone appears with the following parameters:
|
Fixed IP (static) |
When this option is selected, the IP address of the interface will be static. A grid appears, in which you must add the IP address and its subnet mask. Several IP addresses and associated masks can be added if aliases need to be created, for example. These aliases allow you to use the firewall as a central routing point. As such, an interface can be connected to various sub-networks with a different address range. If you add several IP addresses (aliases) to the same address range, these addresses must all have the same mask. Reloading the network configuration will apply this mask to the first address and a /32 mask to the addresses that follow. |
