CONFIGURAZIONE CISCO 1721

[conte123]

Salve a tutti,
Vi scrivo di seguito la configurazione, credo correttamente effettuata, perchè ho potuto vedere che mi autentico al gestore, faccio ping verso i DNS ma non riesco ad uscire sulla rete Internet.

Questa è la mia configurazione:

Secondo Voi è forse un problema di NAT? O cosa può essere? Mi date una mano?

Grazie per la disponibilità
