Oh I love reminding things like that.
Right on time, @alefattorini. 18 months later? Whatever…
Anyway: it was the “at the time” the fastest VPN experience i’ve ever had, Net2Net between the same version and level update of NethServer with already NATed ports for both endpoints. So the 5 minutes experience was a little biased by adequate preparation of everything (i already did my homework about networking, subnetting, ranges).
Today i would like to have more options about cypher, ad a bit of bwm “out of the box” for traffic coming from the “trusted VPN Network” on both sides.
Gold is always gold even 18 months later 
Good suggestion it could be good for a more advanced configuration
