RAP failover to same controller, different interface?

    I have controller with two WAN connections, both own interface and static IP. Can I use LMS to create failover trough different WAN interfaces to same controller in case another WAN connection fails?  Or is this doable at all?

    Not sure if this is doable, because despite having two interfaces, the controller will only have a single best route back to the RAP out of a single interface.  That can certainly change, but ONLY if the physical controller interface goes down.  So if you have an upstream failure of a WAN connection, for example, the controller will not detect it.

    Ah, thats a bit turn off. Most likely its the upstream DSL link that fails than ethernet link between controller and DSL modem. I suppose I'll settle with some persistent options then.

    If you could do OSPF between the controller and your upstream routers and they can give you default route, you may be able to work something out.
