Thanks, @mactrent . I appreciate your input.
Indeed, the excellent how-to is excellent. But only for those who need to set-up TURN & STUN. I’m still not convinced that I must.
In spite of the documentation stating that this “works out of the box” I suppose that eventually I may have to take your word for this, even though it currently seems dubious in light of what the devs have haphazardly written. What would make me much more confident in your advice is if the author of “works out of the box” can chime in and tell us exactly what “working out of the box” means.
To me, “works out of the box” suggests that one doesn’t have to create another box to get this working! Does this not mean the same to you?
