Use this tab to enable WAN automatic switching, set WAN priorities, and configure keep alive.
WAN Automatic switch: By default, automatic switching for WAN is enabled, which allows rerouting of network traffic to another connection if your primary connection fails.
Enable WAN keep alive: When this box is checked, keep alive verifies lookup addresses to check the internet connectivity on the WAN connection.
Lookup Address 1: Enter the first IP address to verify the WAN connection.
Lookup Address 2: Enter the second IP address to verify (if Lookup Address 1 does not respond with keep alive acknowledgement (ACK)).
Lookup Address 3: Enter the third IP address to verify (if Lookup Address 2 does not respond with keep alive ACK).
Keep alive interval: Enter the desired number of seconds without receiving a valid packet before the first keep alive verification occurs. The default is 86400 seconds.
Number of attempts: Enter the number of times to retry after verification failure for all three lookup addresses. The default is 3 attempts.
Retry interval: The number of seconds between verification retries. The default is 600 seconds.
WAN failback interval: The interval used to re-activate the priority WAN interface after the device has failed over to a backup WAN interface. For example, if cellular WAN is your priority WAN interface, this interval allows the device to resume use of a cellular WAN connection after it has failed over to an Ethernet WAN interface. The interval begins when the active WAN interface has failed over to a backup WAN interface. Once the interval expires, the device re-establishes the priority WAN interface as the active connection. The default interval is 15 minutes.
When WAN automatic switching is enabled, WAN switching is determined by connectivity testing. To turn connectivity testing off, uncheck the Active box.
Use this table to configure Ethernet WAN ports as WAN or LAN and to set a priority for your WAN interfaces.
