WAN1: Select "ADSL" "EWAN" or "3G" mode for WAN1.
WAN2: Select the left WAN mode for WAN2 as backup port. For example, if 3G is set for main port, then
there can be no option for failover/failback.
Time Schedule: A self defined time period. You may specify a time schedule for failover/failback
functioning. For setup and detail, refer to Time Schedule section.
Keep Backup Interface Connected: Select Enable this function, the backup WAN port will connect
always.
Connectivity Decision: Set how many times of probing failed to switch backup port.
Failover Probe Cycle: Set the time duration for the Failover Probe Cycle to determine when the router
will switch to the backup connection (backup port) once the main connection (main port) fails.
Note: The time set is for each probe cycle, but the decision to change to the backup port is
determined by Probe Cycle duration multiplied by connection Decision amount (e.g. From the image
above it will be 60 seconds multiplied by 5 consecutive fails).
Failback Probe Cycle: Set the time duration for the Failback Probe Cycle to determine when the router
will switch back to the main connection (main port) from the backup connection (backup port) once the
main connection is communicating again.
Note: The time set is for each probe cycle, but the decision to change to the backup port is
determined by Probe Cycle duration multiplied by Connection Decision amount (e.g. From the image
above it will be 60 seconds multiplied by 5 consecutive fails).
Detect Rule:
Rule 1. ADSL Down
Rule 2. Ping Fail
 No Ping: It will not send any ping packet to determine the connection. It means to disable the ping
fail detection.
 Ping Gateway: It will send ping packet to gateway and wait response from gateway in every
"Probe Cycle".
 Ping Host: It will send ping packet to specific host and wait response in every "Probe Cycle". The
host must be an IP address.
