I'm having toruble with a basic configuration DMVPN. In the debugging I can see how ISAKMP phase 1 completes, but them the phase 2 proposal fails. It says something about a cryptomap that doesnt exists. I thought that with these configuration I didn't need a cryptomap. The routers configuration and the debug print screen are attached. Any help would be aprreciated.

Also, since both the spoke and the hub are behind NAT you'll need NAT-T, so definitely don't disable it.
