Salve a tutti!
Sono un principiante, vi chiedo se potete darmi una mano. In azienda abbiamo acquistato una linea Alice 20Mb della Telecom (ip pubblici da 94.**.**.176 a 94.**.**.182, default gateway 94.**.**.177), ho provato questa configurazione su un cisco 877, ma non funziona.
Questi i problemi:
dal router riesco a pingare ip pubblici, (per esepio quello di google), ma non a pingare i domini (
www.google.it); ho provato anche con altri server dns;
dal pc non riesco a navigare e non pinga nessun ip pubblico, riesco solo a pingare l'ip della vlan1 del router (192.168.1.1).
Il pc ha indirizzo 192.168.1.10 e il default gateway è 192.168.1.1.
Questa è la configrazione del router
