I don't understand clearly about Nat 0. For example:
If I configure 1 interface OPERATION(address 10.20.0.0/24 with nameif 60) and I configure Nat 0 for address 10.20.0.0.
1)Can traffic from 10.20.0.0 can go to higher level through interface OPERATION.
2)When traffic from 10.20.0.0 go to Internet, traffic need not translate ?
If possible, you can explain more details about Nat 0?
Thank you very much
