Configuring modem settings Configuring the modem interface
When the Ethernet interface can connect to its network again, the FortiGate unit
disconnects the modem interface and switches back to the Ethernet interface.
Stand alone mode
In stand alone mode, the modem interface operates as the primary connection to
the Internet. The FortiGate unit routes traffic through the modem interface, which
remains permanently connected to the dial-up account.
If the connection to the dial-up account fails, the FortiGate unit modem
automatically redials the number. The modem redials the ISP number based on
the amount of times specified by the redial limit, or until it connects to a dial-up
account.
Configuring modem settings
To configure the modem settings, go to System > Network > Modem.
