The "NATURAL" has been an automatic spell checking of my tablet. It should have been "NAT".

As you can see in the trace: The P-CSCF forwards the REGISTER request to which is not the I-CSCF (and not prepared to receive such messages).
You should check the forwarding to I-CSCF in kamailio-pcscf.cfg.

Next time you should start with the trace also at startup of the x-CSCF to see that the Diameter connections are up and running.
