DMVPN - hub and spoke behind nat - EIGRP flapping, one way neighbour ?

Hi all

 

I have an issue i hope somebody can help me with it.  I have a DMVPN setup i am labbing so far with only a single spoke and a hub, at this point the tunnel comes up and EIGRP forms on the hub, but not the spoke.  The Hub and spokes are behind NAT routers doing static NAT's.  I am using VRF's so maybe this is the issue?  Can anybody spot the issue?  I see the below on the hub.

This was fixed by rebooting the spoke in GNS3.....
