Bonjour, je suis débutant en Linux.
J’ai donc installé une machine VirtualBox sur Debian7. Le problème est pour accéder à internet. VB sur l’onglet réseau ne me permet pas d’activer une connexion par pont, et NAT n’aboutit pas.
Pouvez vous m’apporter quelques suggestions ? Les sujets que j’ai pu consulter sont souvent spécialisés et je n’y capte pas grand chose.
Merci pour votre aide 
Voici les infos que j’ai pu collecter :
