En effet, si j'installe ubuntu par défaut, firefox ne me permet pas d'accéder à internet... mais une requête de ping marche ! Après un moment d'expérimentation et quelques discutions autour de moi, j'en ai conclu que mon routeur faisait des choses bizarres après les requêtes en IpV6 de firefox. En effet, suite à une remarque sur ce forum, j'ai constaté qu'en mettant "network.dns.disableIPv6" à true dans firefox (about:config etc), là aucun problème ne se posait pour firefox ! Actuellement j'utilise le serveur DNS de mon FAI (j'ai modifié mon resolv.conf) qui marche correctement lui, mais je cherche à mieux cerné le problème avec mon routeur. Ca n'est donc pas necessaire de me dire d'intaller mon propre serveur DNS sur mon PC ;). J'ai fais des essais avec ethereal. Vous constaterez que mon routeur me renvoit une ip 1.0.0.0 "après" les requêtes en ipV6, enfin après une requête ipV4 qui suit une requête ipV6. Ma config : 192.168.1.1 est l'ip de mon routeur qui fait passerelle, serveur dhcp et serveur DNS. 192.168.1.3 est l'ip de mon PC Ci après : - la requête (ipV6) de www.free.fr par firefox : frame 1 à 6 - une requête ARP de mon routeur : frame 11 et 12 (pas necessaire ici) - suivit de la requête de la commande ping : frame 13 à 14 (Exusez moi pour la balise pre, mais je n'ai pas trouvé autre chose pour conserver les espaces devant certaines lignes).
