Configuring Failure Check
It is possible for a WAN interface to go down without the router recognizing the failure. (For example: the carrier for a cellular modem goes dormant,
or your Ethernet connection is properly attached to a modem but the modem becomes disconnected from its Internet source.) Enable Failure
Check to ensure that you can get out to the Internet via your primary WAN connection. This option is disabled by default because it may use data
unnecessarily. Use this in combination with failover. For cellular modems, use this in combination with Aggressive Reset (Internet > Connection
Manager under Modem Settings in the interface/rule editor).
Idle Check Interval: Set the number of seconds the router will wait between checks to see if the WAN is still available. (Default: 30 seconds.
Range: 10-3600 seconds.)
Monitor while connected: Select from the dropdown menu. (Default: Off.)
• Active Ping: A ping request will be sent to the Ping Target. If no data is received, the ping request will be retried 4 times at 5-second intervals.
If still no data is received, the device will be disconnected and failover will occur. When "Active Ping" is selected, the next line gives an
estimate of data usage in this form: "Active Ping could use as much as 9.3 MB of data per month." This amount depends on the Idle Check
Interval.
• Off: Once the link is established the router takes no action to verify that it is still up.
Ping IP Address: If you selected "Active Ping", you will need to input an IP address that will respond to a ping request. This IP address must
be an address that can be reached through your WAN connection (modem/Ethernet). Some ISPs/Carriers block certain addresses, so choose an
address that all of your WAN connections can use. For best results, select an established public IP address. For example, you might ping Google
Public DNS at 8.8.8.8 or Level 3 Communications at 4.2.2.2. Click NEXT.
