Titolo: help per favore sto impazzendo: cisco 803

Salve,
sto usando un cisco 803 per collegarmi a telecomony internet ma pur
usando le configurazioni standard che ho trovato su internet, il ppp
multilink non va.
Ho provato ad usare vari ios diversi e ho addirittura cambiato la
borchia NT1+ ma il problema e' lo stesso. Quindi dovrebbe essere un
problema di configurazione. Inoltre prima usavo un winxp con un TA
interno e questo andava tranquillamente in multilink a 128K (con tanto
di sospensione a 64k e rilancio a 128).
In pratica se faccio partire il router con il ppp multilink o anche se
lo imposto a mano dopo che la connessione a 64k si e' stabilita, il
router immediatamente butta giu' la prima connessione e poi tenta di
riconnettersi senza successo:
*Mar  1 01:02:54: %LINK-3-UPDOWN: Interface BRI0:2, changed state to
down
*Mar  1 01:02:54: %DIALER-6-UNBIND: Interface BR0:2 unbound from
profile Di1
*Mar  1 01:02:56: %LINK-3-UPDOWN: Interface BRI0:2, changed state to up
*Mar  1 01:02:56: %DIALER-6-BIND: Interface BR0:2 bound to profile Di1
*Mar  1 01:02:57: %ISDN-6-CONNECT: Interface BRI0:2 is now connected to
7010187187 stack1
*Mar  1 01:02:57: %LINK-3-UPDOWN: Interface BRI0:2, changed state to
down
*Mar  1 01:02:57: %DIALER-6-UNBIND: Interface BR0:2 unbound from
profile Di1
*Mar  1 01:02:59: %LINK-3-UPDOWN: Interface BRI0:2, changed state to up
*Mar  1 01:02:59: %DIALER-6-BIND: Interface BR0:2 bound to profile Di1
*Mar  1 01:03:00: %ISDN-6-CONNECT: Interface BRI0:2 is now connected to
7010187187 stack1
*Mar  1 01:03:00: %LINK-3-UPDOWN: Interface BRI0:2, changed state to
down
quindi rimango senza alcuna connessione attiva.
Riassumendo, a 64k il router si collega ed esce regolarmente: appena
imposto i 128k con ppp multilink subito si scollega, prova e riprova ma
subito si riscollega. Se rimetto "no ppp multilink" tutto torna a
funzionare (ma a 64k).
Inoltre a 64k non mi funziona il nat in uscita, cioe' dagli ip degli
altri pc collegati alla rete interna non si esce su internet (pur
raggiungendo il router).
Prima di postare le info di debug, vi chiederei di dare uno sguardo
alla mia conf e suggerirmi se c'e' qualcosa che posso provare.
Ho poi bisogno di usare il callbumping...
Grazie mille!

 Salve,

Ciao
Per il multilink...
prova a postare l'output di un debug  ppp authentication
per il nat ti manca la regola di "natting"
ad esempio...
ip nat inside source list 10 interface dialer0 <<<----  questo per fare in
modo che il router utilizzi l'ip che verrà assegnato all'interfaccia Dialer0
per traslare le richieste verso Internet  della tua LAN
poi....
access-list 10 permit 192.168.0.0 0.0.0.255

Ciao
Credo che tu debba usare solo un tipo di autenticazione e poi configurare il
ppp multilink
prova a configurare solo il pap lasciando sulla dialer solo questo...
ppp authentication pap callin
 ppp pap sent-username telecom password 0 telecom
ppp multilink
se non dovesse funzionare con questa cambiala con il CHAP...
Ciao
Carlo

ciao a tutti, anche io ho lo stesso problema....ho provato a fare le
modifiche suggerite ma niente. ho spiegato meglio il problema
qui.....vi prego aiuto!!!!

ciao e grazie.....ho provato la tua configurazione ma niente.....sempre
le stesse connessioni/disconnessioni continue. Ho provato anche con un
altro provider.....idem. A questo punto non so veramente che fare,
l'unica cosa che mi resta da fare è provare ad aggiornare l'ios
perchè il mio è vecchiotto 12.0(5), e ad esempio certi comandi della
tua configurazione non li riconosce allo startup. Tu che versione
hai....la 12.3? ho provato a cercarla in rete ma non la trovo....non è
che per caso me la puoi passare?
