Situation: The client configures dual site to site VPN connecting to AWS using two ISPs, AT&T and Comcast. They configure both Active-active load balance and failover. They would like to know how to switch between Balance and Failover.
Resolution: assuming both configuration are correct and they are using Active-active balance, you just need to check Fail Over under Monitor Profile by going to Network>Network Profile>Monitor.
Commit to save the change.
