ho un'adsl 2+ a 20 MB/1MB con Infostrada su ULL
Premetto che ho gia' testato la linea con un altro router e funziona tutto
Ho configurato il Cisco 877 usando SDM Express
Sia IOS che il firmware che SDM sono tutti all'ultima versione (il rivenditore Cisco mi ha aggiornato tutto prima di darmi l'apparato)
Il problema e' che la portante viene rilevata correttamente (19999 down e 996 up) con un'ottima attenuazione (14 dB, ossia 1 km dalla centrale telecom) e l'interfaccia Dialer0 riceve l'IP dalla rete
Tuttavia, ne' dal router ne' dagli host della rete e' possibile pingare o navigare (ho provato sia nomi dns che ovviamente anche IP diretti)
Qualche tempo fa avevo avuto lo stesso problema e si trattava di settare MTU e MSS, attualmente SDM li ha configurati di suo a 1452, quindi non dovrebbero esserci problemi a riguardo
Vi posto di seguito la configurazione e alcuni show (versione, ip brief e adsl) spero che qualcuno di voi possa aiutarmi
Piccola nota banale: FastEthernet0 era in quel momento down perche' ho staccato il cavo per usare l'altra connessione, quando e' up non ci sono problemi (DHCP va, pingo il router, SDM si apre,...)
Grazie tantissimo
Ciao
