Configuring the modem interface

50A

The modem interface is only available on the FortiGate-50A.

The following sections will cover how to configure the FortiGate-50A modem using the CLI.

The FortiGate-50A supports a redundant or stand alone 56K modem interface in NAT/Route mode.

In redundant mode, the modem interface automatically takes over from a selected Ethernet interface when that Ethernet interface is unavailable.

In stand alone mode, the modem interface is the connection from the FortiGate unit to the Internet.

When connecting to an ISP in either configuration, the modem can automatically dial up to three dial-up accounts until the modem connects to an ISP.

Connecting a modem to the FortiGate-50A

The FortiGate-50A 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.
