dmvpn tunnels with two isps on single spoke using nat

Looking for a dmvpn config with two isps on single spoke behind a ASA (nat).  
Basically I have DMVPN working right now off of Primary ISP, but I would like to add the secondary ISP for failover.
Has anyone done this with an ASA (Two ISP's are on the ASA)  and a single uplink to the DMVPN router?

If you go through the trouble of getting the NAT to work, the routing coming in will still have to choose one path over the other, so now we are looking at BFD. Suggest you don’t go down that path of pain, sdwan handles this so much easier.

? The ASA does not support Dynamic Multipoint GRE encapsulation ?

You need a router.

Before I'm shouted at - yes it supports VTI now, but it still does not support DMVPN.

I'd think you could create a second default router with a higher AD on the ASA. The ASA is just forwarding traffic and is not part of the DMVPN, so it shouldn't be an issue having the ASA in front of the DMVPN router. As for natting, you should be able to create NAT's to the DMVPN router for the ISP2's addressing as well on the ASA.

I must be missing something . . . redundancy on a DMVPN spoke? I don't see the architectural difficulty.

Are you running BGP throughout the DMVPN?

Have fun!
