Configuring the modem interface

See “To add a ping server to an interface” on page 100.
6 Configure firewall policies for connections to the modem interface.
See “Adding firewall policies for modem connections” on page 106.
Standalone mode configuration
In standalone mode, the modem connects to a dialup account to provide a
connection to the Internet. You can configure the modem to dial when the
FortiGate unit restarts or when there are unrouted packets. You can also hang up
or redial the modem manually.
If the connection to the dialup account fails, the FortiGate unit will redial the
modem. The modem redials the number of times specified by the redial limit, or
until it connects to a dialup account.
There is an optional timeout setting, after which the modem will disconnect if there
is no network activity. This is useful in saving money on dialup connection
charges.
You must configure firewall policies for connections between the modem interface
and other FortiGate interfaces.
You must also go to Router > Static to configure static routes to route traffic to the
modem interface. For example, if the modem interface is acting as the FortiGate
unit external interface you must set the device setting of the FortiGate unit default
route to modem.

1 Go to System > Network > Modem.

4 Configure firewall policies for connections to the modem interface.
See “Adding firewall policies for modem connections” on page 106.

interface. For these routes, set device to Modem.
See “Adding a static route to the routing table” on page 238.
