Unable to create VPN tunnel using Cradlepoint

Hi all, my company purchased a Cradlepoint to use as a failover ISP for when our primary goes down.

We can not seem to get a VPN tunnel created when using the cradlepoint.

The ASA is stuck on MM_WAIT_MSG2, they are Cisco ASAs on both ends.

It doesn't seem like the other end is getting the request we send, however if we bring up the other interface for our primary ISP the tunnel builds just fine.

I can link the debug file from this end, the error seems to be:

Sending delete/delete with reason: Ignoring IKE SA (dst) without VM bit set;

Also fwiw the Cradlepoint is in IP Passthrough mode, and that interface is setup to dhcp that address.
