PPPoE Pass Through
This option controls whether LAN computers can act as PPPoE clients and negotiate the
PPP sessions through the router over the WAN ethernet link.
Enable PPPoE Pass Through
Enabling this option allows LAN computers to act as PPPoE clients. Disabling this option
prevents LAN computers from establishing PPPoE pass-through connections.
FAILOVER
The router can establish an uplink via the ethernet WAN port or any modems plugged into the
USB, ExpressCard or CardBus ports. Although all of these devices may be plugged in, only one
of them may establish a link at a time. If the WAN connection fails the router will automatically
attempt to bring up a new link on another device. This feature is called failover.
WAN Failure Detection
WAN failure detection works by detecting the presence of traffic on the ethernet WAN
link. (Note that this only applies to the ethernet WAN link, not the modems.) If the link is
idle for too long the router will attempt to ping a target IP address. If the ping does not
reply, the router assumes the link is down and attempts to fail over to a modem.
Enable
This enables failure detection on the ethernet link. Even when this is disabled unplugging
the ethernet cable at the WAN port will trigger failover to a modem.
Timeout
If the ethernet link is idle for this amount of time then the router will either send a ping or
failover to a modem.
Enable Ping on Idle
When enabled, the router will send a ping after the link idle timeout. If the ping gets a
reply, the router will restart the idle timer, otherwise it will failover to a modem.
Ping Target
The default ping target is the router's gateway. You may specify a different IP address as
a target here.
WAN Interfaces
This section allows you to change the failover order of devices (aka interfaces); to
monitor their status; to take the active link down; or to bring a link up on another device.
The device at the top of the list has the highest priority. This is the device which the
router will attempt to start when it boots up. If the link cannot be brought up on this
device, or if it goes down later, the router will attempt to bring the link up on the next
available device. Whenever a link fails on a device, the router will always move down to
the next device down in the list, and wrap around again to the top.
