We are planning to build a DMVPN setup. The hubs all plan to have static Public IPs. The spokes however, in some cases will sit behind an ISP router and have private IPs. In some cases they will have LTE CG-NAT IPs.
We only need Spoke to Hub tunnels. We don't need spoke-to-spoke tunnels.
Is this doable if the DMVPN spokes don't have public IPs? We need to assume that no port-forwarding from Out to IN is possible for these private IPs.

@ronit The spokes will initiate the tunnel to the hub(s), so yes the spoke routers can be behind a NAT device and establish a tunnel to the hub
