NAT su cisco 2610
Inviato: gio 19 mar , 2009 9:43 pm
Ho un problema con il nat su un router 2610 con ios
c2600-d-mz.121-27b.bin.Il trunk va bene, dalla rete interna riesco a raggiungere sia la Ethernet0/0.1 che la Ethernet0/0.2 che l'interfaccia seriale0/1,ma al momento di uscire fuori...... NIENTE:controllando i log non mi viene segnalato nulla.
Non so piu' che pesci prendere: che sia l'ios un po' vecchiotto ?????Purtroppo ho problemi di flash e di Ram.
Penso pero' che per fare una schifezza di nat vanno bene anche quelli non proprio recenti o ...no ..... BOH
Qualcuno puo' darmi una mano ?? Grazie
