system starts the failback process.
S 5: When failback process starts, system terminates the current WAN connection via Failover
WAN interface.
S 6: System changes the data routing path back to the primary WAN interface as same state as at
the beginning of system normal operation.
 Seamless Failover Scenario:
As another example, all parameter configuration for WAN‐1 and WAN‐2 is same as above example
except the "Seamless" box is checked as bellow (in red color).

When the "Seamless" enable checkbox is activated, it can allow the Failover interface to be
connected continuously after system booting up. The Failover interface just keeps connecting but
without data transfer. The purpose is to aim at the shortening of switch time during failover
process. So, when primary connection is disconnected, failover interface will take over the data
Index skipping is used to reserve slots for new function insertion, when required.
