Bonjour,
Je souhaite remplacer complètement ma Freebox par les équipements suivants :
- Un routeur Cisco 2821 équipé d'un module ADSL2+ (HWIC-1ADSL-M)
J'utilise la dernière version de l'Advanced Enterprise Services, IOS version 15.1(4)M7
- Un switch Cisco 2960G qui sera raccordé au 2821.
Je suis en dégroupage totale avec l'opérateur Free (donc IP over ATM je pense ?!)
Les spécifications de ma connexion :
Adsl :
======
Etat Showtime
Protocole ADSL2+
Mode Interleaved
Descendant Montant
-- --
Débit ATM 6570 kb/s 887 kb/s
Marge de bruit 5.40 dB 7.30 dB
Atténuation 46.00 dB 25.00 dB
FEC 5211 27735
CRC 76 0
HEC 3 267
Je souhaite que mon routeur Cisco se comporte à l'identique de ma Freebox, c-a-dire :
Coté WAN, le routeur récupérera l'IP du DSLAM via le module HWIC ADSL qui sera paramétré avec l'@ MAC de ma BOX.
Coté LAN, le routeur CISCO proposera une config DHCP avec une passerelle par défaut en 192.168.1.50 + DNS récupérés via la conf. IP de l'opérateur (Lan en /24) pour les équipements IP raccordé sur le switch.
J'aurai besoin de faire du port forwarding pour certaines application (un ou deux exemples me serait utile)
J'accède et paramètre chaque équipement en port console via Putty.
La conf du routeur actuellement :

J'ai caché volontairement les mot de passe, adresse mac et numéro de série.
A noter que la commande "dsl operating-mode auto" ne s'enregistre pas quand je la rentre sur l'interface ATM0/0/0, mais il semble que par défaut l'interface soit en auto d'après la documentation Cisco.
La connexion au DSLAM semble se faire correctement, voyant vert clignotant, puis fixe au niveau du module, pas de deconnexion/reconnexion intenpestive.
La connexion ne fonctionne pas... voici les infos que j'obtiens quand j'interroge les interfaces :

J'ai fait deux tests supplémentaires en modifiant l'interface ATM0/0/0.1 : dans un cas avec mon IP Wan en static ou en DHCP => KO dans les deux cas.
Voici les résultats :

J'ai besoin d'un peu d'aide pour établir la configuration sur le routeur, mes connaissance étant limité pour réaliser une conf aussi complexe.
Merci pour votre aide.
