Configuring the modem interface

This chapter describes the modem interface configuration options. The FortiGate unit supports the modem interface only when running in NAT/Route mode.

You can configure the modem interface for stand alone mode, the direct connection to the Internet, or for redundant mode, to act as a backup connection to the Internet, should the primary connection fail.

This chapter includes the following topics:

•Selecting a modem mode

•Configuring modem settings

•Configuring the modem using the CLI

•Adding a Ping Server

•Adding firewall policies for modem connections

•Administrative access through the modem port

•Configuring the PCMCIA modem card

Selecting a modem mode

The modem interface can work in one of two modes: redundant and stand alone mode.

To select an operational mode for the modem interface

1Go to System > Network > Modem.

2Select Enable modem.

3Select Redundant for the mode.

To select an operational mode using the CLI, type:

config system modem set status enable

set status mode redundant end

Redundant mode

The redundant modem interface is a backup to the external interface connected to the Internet. If the Ethernet connection goes down for whatever reason, the modem automatically dials the configured dial-up account(s). When the modem connects to a dial-up account, the FortiGate unit routes IP packets normally destined for the selected Ethernet interface to the modem interface. During this time, the FortiGate unit pings the Ethernet connection to check when it is back online.
