an old post, but I am looking for the same thing, my scenario is ssl s2s vpn on the client side I have two uplink interfaces on uplink1 goes down the connection will be re-established through uplink2 , but when uplink1 is up again the connection don't fall back to it, it will stay through uplink2 I have created some multipath rules but it didn't work Did you manage to find a solution?
Thanks Balfson, I know it is one hour, but it is not working like that with SSL vpn connection it will remain connected through uplink2 until I set it back manually
