Ciao..

Spesso è un falso errore.
Configura ip inspect e aggiorna la ios

Spesso è un falso errore.

Ok.. ma allora dovrebbe funzionarmi, invece non riesco a pingare l'esterno dal router

Configura ip inspect e aggiorna la ios

L' IP INSPECT non c'entra però con l'errore no?
per quanto riguarda la IOS è un router nuovo appena spedito da esprinet, comunque provo a verificare che IOS monta.

Grazie

Ma il comando te lo mette poi in config o no?

Inviato: **mar 05 feb , 2008 10:04 pm**

si... quello che ho postato è lo show config che c'è su adesso...

questo invece è il log di un restart dell'857, come vedi anche qui mi riporta l'errore del NAT:

I protocolli ATM sono UP, però se tento di pingare l'esterno non risponde..
Ho chiesto conferma a Telecom degli ip e sono tutti corretti, non riesco a capire dove sia il problema.
Telecom dice che vede l'interfaccia quindi non è un problema loro (.strano..)

mi sto perdendo un po' ..

Spero tu abbia la possibilità di aggiornare la ios...

Mi pare che è più vecchio del tuo e con IOS inferiore e a me va... strano...
