Bonjour tout le monde 
Je suis actuellement connecter sur mon VPN ( héberger chez ovh ), et je constate que le debit est irrégulier ( il passe de 1Mo/s a 0o/s ), sans le VPN je stagne dans les 250Ko/s.
Du coter du ping je passe de 70+ à 40.
Pour les jeux en ligne sa passe mais les client perdent la connection au bout d’un certain temps ( de 5 a 60min ).
=Le debit ne stop pas a 0o/s mais reste a 25/50Ko/s.
Pour le streaming et la navigation internet vue le debit je peut DL d’un coup a 1Mo/s ( sa change de mon debit habituel ^^, mais juste apres sa stop et bloque a 0o/s pour repartir a fond a 1Mo/s et sa constamment )
Voici ma config:
