Connecting a modem to the FortiGate unit

FortiGate-60 Administration Guide
You can connect a modem to the FortiGate unit and use it as either a backup interface
or standalone interface in NAT/Route mode.
• In backup mode, the modem interface automatically takes over from a selected
ethernet interface when that ethernet interface is unavailable.
• In standalone mode, the modem interface is the connection from the FortiGate unit
to the Internet.
When connecting to the ISP, in either configuration, the FortiGate unit modem can
automatically dial up to three dialup accounts until the modem connects to an ISP.

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.
