Bonjour,
Le routage est aléatoire chez moi en IPv6. Je n'arrive pas à identifier le problème. Quelqu'un à essayer un traceroute6 vers un de mes serveur (container LXD).

La dernière IP est celle de mon routeur, un Zyxel VMG8823-B50B à l'interface bugguée comme pas possible. Quasi impossible à configurer. Mon FAI est OVH.
Depuis ce containeur, ça semble fonctionné
