mi chiamo Valerio, ho 26 anni, sono di Roma e da ottobre frequento il CCNA (all'Elis).
Seguo il forum da diversi mesi in modalità "passiva"
, ora un po' per smanettare un po' per sostituire un netgear (che devo ammettere essere un vero trattore!) mi sono regalato un 857 (affarone su ebay!! solo 70€ sigillato, è buono no?) e facendo un bel collage di configurazioni (il 90% è la conf di Wizard, il quale ringrazio) sono riuscito a metterlo Up and running.Ho passato le ultime due notti cercando di capire tutti i comandi presenti nel file di conf e devo dire che ho imparato tantissimo (il corso mi darà poi le basi concrete), non riesco però ad individuare quale sia il problema che continua a far si che ottenga un bel CONFIGURATION FAILED! all'avvio della macchina (e qui mi inginocchio sui ceci chiedendovi di darci uno sguardo).
Il router funziona "perfettamente" (metto le virgole perchè proprio quel failed mi mette il dubbio..), nel senso che da una prova fatta da un client navigo (poi dovrò sicuramente fare un po' di tweaking sui parametri ma questo moolto più in là).
Naturalmente siete liberi di correggere eventuali cappell..e!! (siate però magnanimi!!)
