Connecting a modem to the FortiGate unit

The FortiGate unit can operate with most standard external serial interface modems that support standard Hayes AT commands. To connect, install a USB-to-serial converter between one of the two USB ports on the FortiGate unit and the serial port on the modem. The FortiGate unit does not support a direct USB connection between the two devices.
