come da titolo, ho un cisco 1841 con 2 wic adsl.
ho bisogno di configurare i due wic in modo da ottenere connessione adsl (ogni wic è collegato ad una linea differente)
ed ovviamente aggiungere il nat.
questo mi serve per avere un minimo di ridondanza.
Se una linea fallisce, vorrei che ci fosse la seconda a restare attiva.
tutto ok quando configuro la prima linea adsl su ATM0/0/0 con NAT overload.
la fa0/0 va sulla mia LAN, quindi con nat inside.
quando provo a configurare la seconda linead adsl su ATM0/1/0, non ottengo nessuna connessione...
avrei anche bisogno di un aiuto con la configurazione del NAT, visto che nat overload sembra lo possa applicare su una sola interfaccia.
questa è la mia configurazione:
