Re: NAT using only a real interface?

Are you asking if you can have a PRIMARY address of 123.123.123.1/24 on E0
and THEN put a secondary address of 192.168.1.0/24 on the SAME interface
and THEN NAT between the two? If that is your question then no (and WHY?)

If you are asking if IP address 'A' can be placed on ethernet interface '0'
and then IP address 'B' placed on ethernet interface '1' and then NAT
between the two then YES.

If you need documentation on how:

http://www.cisco.com and search for 'Network Address Translation' in the
Technical Documents area.
