Introduction In some scenarios, you want to be able to failover to another WAN in case your main link goes down. I prepared this tutorial to explain how to achieve that with RouterOS and the ability to send a notification using Twitter on Failover events. How it works Basically, the script will ping Google DNS 8.8.8.8 every 5 minutes using the main route (wan1), if it fails to ping, the script will change the distance of the main route by setting the value to 3 or any value higher than the second route (wan2).
