Configuring the modem interface

The FortiGate-60M includes an internal 56K modem for use as either a redundant
interface or a standalone 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 standalone 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 dialup accounts until the modem connects to an ISP.

This chapter describes:

•

Selecting a modem mode

•

Configuring modem settings

•

Connecting and disconnecting the modem in Standalone mode

•

Defining a Ping Server

•

Adding firewall policies for modem connections

Selecting a modem mode

The internal modem in the FortiGate-60M can work in one of two modes, depending
on your requirements:

• redundant mode
• standalone mode.

Redundant mode configuration

The redundant modem interface in redundant mode backs up a selected ethernet
interface. If that ethernet interface disconnects from its network, the modem
automatically dials the configured dialup account(s). When the modem connects to a
dialup account, the FortiGate unit routes IP packets normally destined for the selected
ethernet interface to the modem interface. During this time, the unit pings the ethernet
connection to check when it is back online.

When the ethernet interface can connect to its network again, the FortiGate unit
disconnects the modem interface and switches back to the ethernet interface.
