How do I NAT a public IP range to a private range

This may be a dumb question.  I am trying to NAT a series of internal servers to public IPs in a one to one fashion.  I have a series of static NATs in place now with only the first and last one working.

    If we wanted to access our DMZ Web server server via the outside/public interface (example access to a DMZ PC via a public IP)

    static (dmz,outside) [NAT_IP] [Real_IP]

    Accepted Solution

    One to one, use:

    Static (inside,outside) public_ip private_ip netmask
    So let's say you want to nat to Then it would look like:

    Static (inside,outside) netmask
    Of course you need an access-list on the outside to allow the appropriate ports though.
    So what's wrong with the current NATs? Could you show us?
