Bonjour,
J'ai installer un serveur pré-configuré avec OpenVZ de chez OVH et j'ai des problème avec le reseau. mon VPS ping l'hote mais l'inverse ne fonctionne pas (l'hote ne ping pas le VPS)
l'hote à 2 adresse (eth0 & eth0:1), l'une publique l'autre privée (meme zone d'adresse que le VPS)
SUR la MACHINEHOTE
