IPv6 Failure Check (Advanced)

These settings match IPv4 Failure Check; the only

difference in the UI is that the ping address uses IPv6.

Failback Configuration (Advanced)

This is used to configure failback, which is the ability to go back to a higher priority WAN interface if it regains connection

to its network.

Usage: Fail back based on the amount of data passed

over time. This is a good setting for when you have a

dual-mode EVDO/WiMAX modem and you are going in

and out of WiMAX coverage. If the router has failed over

to EVDO it will wait until you have low data usage before

bringing down the EVDO connection to check if a WiMAX

connection can be made.

• High (Rate: 80 KB/s. Time Period: 30 seconds.)

• Normal (Rate: 20 KB/s. Time Period: 90 seconds.)

• Low (Rate: 10 KB/s. Time Period: 240 seconds.)

• Custom (Rate range: 1-100 KB/s. Time Period range: 10-300 seconds.)

Time: Fail back only after a set period of time. (Default: 90 seconds. Range: 10-300 seconds.) This ensures that the

higher priority interface has remained online for a set period of time before it becomes active (in case the connection is

dropping in and out, for example).

Disabled: Deactivate failback mode.

Immediate Mode: Fail back immediately whenever a higher priority interface is plugged in or when there is a priority

change. Immediate failback returns you to the use of your preferred Internet source more quickly which may have

advantages such as reducing the cost of a failover data plan, but it may cause more interruptions in your network than

Usage or Time modes.
