Dear Mr. Wouters,

I have succeeded to connect with IKEv1 L2TP IPSEC w PSK from my laptop 
from home ethernet device.
Previous successful connect was also from this Windows 10 laptop.

The version of libreswan is 3.32:

root at domac:/etc/ipsec.d# ipsec version
Linux Libreswan 3.32 (netkey) on 4.19.0-17-amd64
root at domac:/etc/ipsec.d#

Now that I have v1 working, I will try to implement IKEv2 without pressure.

Thank you very much for all the help and the advice. I hope I could 
contact you again if there will be any problems.
I see that libreswan is a powerful tool. It only needs some 
autoconfiguration tool for the novice user, and it
will surely be more widely accepted.

Thank you again.

Kind regards,
Mirsad Todorovac
