tsu,
I already followed the steps you recommended - they don’t give what I am looking for. I am interested in facts, not in guesses, speculations, accusations or small talk.
The topic of this thread is still actual. The questions have been put in the OP and those which remain unanswered have been clarified further. Additional mention of the high-level objective has been made too. A welcome answer would be a shared configuration with a terse explanation.
