Selecting a modem mode

Configuring the modem interface

Selecting a modem mode

The modem interface can work in one of two modes:

redundant mode

stand alone mode

Redundant mode configuration

The redundant modem interface serves as a backup to the Ethernet interface. If that Ethernet interface disconnects from its network, the modem automatically dials the configured dial-up account(s). When the modem connects to a dial-up account, the FortiWiFi 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 FortiWiFi unit disconnects the modem interface and switches back to the Ethernet interface.

For the FortiWiFi unit to switch from an Ethernet interface to the modem, you must select the name of the interface in the modem configuration and configure a ping server for that interface. You must also configure firewall policies for connections between the modem interface and other FortiWiFi interfaces.

To configure a redundant modem connection for the FortiWiFi-60AM

1Go to System > Network > Modem.

2Select Enable modem.

3Select Redundant for the mode.

4From the Redundant for list, select the Ethernet interface you want the modem to back up.

5Configure other modem settings as required. “Configuring modem settings” on page 52.

6Configure a ping server for the Ethernet interface selected in step 4. See “Adding a Ping Server” on page 56.

7Configure firewall policies for connections to the modem interface. See “Adding firewall policies for modem connections” on page 56.

To configure the FortiWiFi-60A using the CLI

1Log into the CLI.

2Enter the following to configure a redundant modem:

config system modem set status enable

set status mode redundant end

Stand alone mode configuration

In stand alone mode, you manually connect the modem to a dial-up account. The modem interface operates as the primary connection to the Internet. The FortiWiFi unit routes traffic through the modem interface, which remains permanently connected to the dial-up account.
