Hi Noel,
thanks for your help.
I've set a Debian 9 pc, so I am now using Strongswan 5.5.1-4 as you
suggested. I cannot get 5.5.3 since is not available under debian. As a
bonus, now my linux kernel is 4.9.0-3.
This are my ipsec.conf (I followed your hints and semplified whatever I
could) and charon_debug.log:
