A RUT951 is being installed on a customer's LAN. The RUT will use the customer's LAN as its primary WAN, but has a SIM card installed as well. I have configured failover between the Customer's LAN and Mobile and confirmed it works.
However, if the customer's LAN comes back up, the RUT keeps routing traffic via the Mobile network. Is this intended behavior, or is there some way to encourage it to un-fail back?
