Hypothetical: I have a server setup behind an EdgeMAX router that has dual WAN fail-over configured
It needs to maintain a persistent site-to-site VPN connection between two other EdgeMAX routers over the internet.
In the event the fail-over is triggered:
How do I notify the other two locations of the change so they can re-establish the VPN connection over the backup WANs using its static IP?
When the primary WAN connection is restored how do I notify the clients to start using the primary WAN again?
