7.7 Traffic Redirect
Traffic redirect forwards traffic to a backup gateway when the Prestige cannot connect to the
Internet. An example is shown in the figure below.
Connect on Demand Select Connect on Demand when you don't want the connection up all the time
and specify an idle time-out in the Max Idle Timeout field.
Max Idle Timeout Specify an idle time-out in the Max Idle Timeout field when you select Connect
on Demand . The default setting is 0, which means the Internet session will not
timeout.
PPPoE Passthrough
(PPPoE
encapsulation only)
This field is available when you select PPPoE encapsulation.
In addition to the Prestige's built-in PPPoE client, you can enable PPPoE pass
through to allow up to ten hosts on the LAN to use PPPoE client software on their
computers to connect to the ISP via the Prestige. Each host can have a separate
account and a public WAN IP address.
PPPoE pass through is an alternative to NAT for application where NAT is not
appropriate.
Disable PPPoE pass through if you do not need to allow hosts on the LAN to use
PPPoE client software on their computers to connect to the ISP.
