DMVPN with two ISPs

Has anyone tried this? I have two 1811 routers with dual ethernet interfaces. All 4 of these interfaces go to different ISPs. I want one router as a hub and one router as a spoke. I would like the DMVPN network to be completely meshed so that if one hub and one spoke interface should fail, there is still a vpn connection.

Re: DMVPN with two ISPs

For the NAT-Transparency Aware enhancement to work, you must use IPSec transport mode on the transform set. Also, even though NAT-Transparency (IKE and IPSec) can support two peers (IKE and IPSec) being translated to the same IP address (using the User Datagram Protocol [UDP] ports to differentiate them [this would be Peer Address Translation]), this functionality is not supported for DMVPN. All DMVPN spokes must have a unique IP address after they have been NAT translated. They can have the same IP address before they are NAT translated.
