Aiuto !! Cisco 801

[matte85]

Innanzi tutto un saluto a tutti, ho una connessione teleconomy internet su isdn, mo ho un problema, ho acquistato un router 801 per sostituire un 760 che uso per connettermi ma non riesco a configurarlo ho provato con fast step ma nulla esce ma rimane connesso qualche secondo poi cade, da telnet durante la connesione mi da questo :

Purtroppo non conosco bene IOS perché ero abituato a settare 760, completamente diverso
Ragazzi potete darmi qualche dritta…. , Io mi collego con 7020191191 ( linea affari)

[CH1CC0]

prova a fare qualche altro test:

"show isdn status"
"debug isdn q921" e "debug isdn q931"
"debug ppp negotiation"
e infine
"debug ppp authentication"

Naturalmente i debug vanno eseguiti uno alla volta (altrimenti affondi il router e rischi non riuscire a capire niente perché ti dà troppe informazioni).

Quando hai fatto, posta i risultati che vediamo di capire perché non va.

[matte85]

provo a fare i test e poi ti dico
CMQ Grazie per la risp .
Un Saluto Matte

[cisketto]

Posta la configurazione cosi possiam darti un aiuto piu concreto!

[V4N3X]

Oppure fai prima: controlla le specifiche di configurazione indicate in QUESTO thread per il tuo router, e vedi se i parametri sono uguali.

Oppure fai prima: controlla le specifiche di configurazione indicate in QUESTO thread per il tuo router, e vedi se i parametri sono uguali.

Nel post manca un bel pezzo di config, quale la config della ethernet, il NAT, e il routing! Fai prima a postare la config e vediamo insieme cosa c'è da aggiungere o da sistemare.

[V4N3X]

A mio parere, se qualcosa non va nella linea non è di sicuro un problema di NAT, anche perche mi sembra che la comunicazione col router via telnet vada bene. Siccome molti lamentano malfunzionamenti ed intermittenze con la linea ISDN, dubito che nessuno di quasti sappia settare un NAT.
Per fortuna mia io non ho mai dovuto avere a che fare con questo tipo di linea, che sicuramente non brilla per efficienza.

[cisketto]

Non voglio dire che sia un problema di nat, mai detto una cosa del genere io ho solo detto che in quel link mancava piu della meta della config minima per fare funzionare il router!

posta il risultato dei vari debug:

show isdn status
debug isdn q921
debug isdn q931
debug ppp negotiation
debug ppp authentication

mi raccomando i debug uno alla volta!

Finalmente dopo una giornata di smanettamenti sono riuscito a far connettere il router , non potete immaginare come , cambiando le password e login da telecom a teleconomy (seguendo discussioni con lo stesso problema , dovuto alla versione di IOS Incompatibile ) ora si connette perfettamente a 7020191191 ma non riesco a visualizzare le pagine , subito ho pensato alla passsword e al user ma poi ho fatto la prova connettendomi con un modem analogico e funziona perfettamente.
Io uso Questa coppia di DNS 212,216.112.112 e 212.216.172.62 con un cisco 700 e funziona ,l'ip del router è lo stesso e '800 è configurato con parametri lan uguali a 700 ma nulla da fare

Come posso risolvere il prob?

MA la pagina di registrazione la visualizzi??

cambiando le password e login da telecom a teleconomy

Come volevasi dimostrare, tutta quella pappardella era inutile, e dovevi ricontrollare i settaggi.

[matte85]

Quale ? Intendi quella per aderire al contratto ?

[V4N3X]

Esatto:
http://dialup.telecomitalia.it/dialu...egistration.do

[matte85]

io sono gia registrato infatti con l'altro router il 700 riesco a visualizzare ,e anche con il modem analogico navigo bene

[V4N3X]

Allora ricontrolla i DNS, che sono errati.
PER FAVORE: vatti a guardare i settagi che ho postato nel link, e prova con quelli.
