Bonjour,
J'ai découvert openvz il y a peu, je pensais m'en être bien sorti. Je m'étais fait un template gentoo qui fonctionnait bien.
Seulement, aujourd'hui, je me fais un autre VE avec le même template, et il n'a pas accès à l'extérieur. Ce n'est à priori pas un problème de parefeu sur le VN.
Pourtant, je ne vois aucune différence :

Je n'y comprends rien.
En fait, mon but n'est pas d'installer un 2ème template gentoo, mais un template debian. Or, avec, j'ai de gros problèmes réseaux (pire qu'ici) donc je tente de passer par cette étape que j'étais censé mieux maitriser.
Merci d'avance à celui qui voudra bien m'aider. Je ne continue pas à balancer tout ce que j'ai déjà fait ici, ça rendrait le post encore plus lourd et illisible, mais je suis évidemment à votre disposition pour de plus amples détails.
