Configuring the modem interface
System Network
When connecting to the ISP, in either configuration, you can configure the
FortiGate unit to automatically have the modem dial up to three dialup accounts
until the modem connects to an ISP.
FortiGate models 50AM, 60M have a built-in modem. For these models, you can
configure modem operation in the web-based manager. See “Configuring modem
settings”.
Other 50 and 60 models can connect to an external modem through a USB-toserial
converter. For these models, you must configure modem operation using
the CLI. See the system modem command in the FortiGate CLI Reference.
Note: The modem interface is not the AUX port which is a port that is used for a remote
console connection. The AUX port has no associated interface. The AUX port is only
available on FortiGate models 1000A, 1000AFA2, and 3000A. For more information, see
the config system aux command in the FortiGate CLI Reference.
Configuring modem settings
Configure modem settings so that the FortiGate unit uses the modem to connect
to your ISP dialup accounts. You can configure up to three dialup accounts, select
standalone or redundant operation, and configure how the modem dials and
disconnects.
You can configure and use the modem in NAT/Route mode only.
