Configuring a connection to the outside network
Configuring advanced WAN/ISP settings
If a line is physically disconnected, then the line is considered disconnected and
the appliance attempts to route traffic to the serial port or the other WAN port.
If the cable is not physically disconnected, the appliance performs line checking
every few seconds to determine if a line is active. If the line fails, it is shown as
disconnected on the Logging/Monitoring > Status tab and an alternate route for
traffic is attempted.
See
“Dial-up accounts”
on page 39 to configure failover for a dial-up account.
See
“Connecting manually to your PPPoE account”
on page 34 to configure a
echo request for accounts that use PPP.
To configure failover
See
“Main Setup tab field descriptions”
on page 164.
