Assuming the following values:

inside native IP address -
outside translated IP address -

Here is the command to translate the inside host at to when sending traffic to any host on the outside interface:

static (inside,outside) netmask

If you want to translate that same inside host for traffic going to a host in a dmz network and you want to use it's own native IP address ( for the translation, then you can use:

static (inside,dmz) netmask

In this fashion, any machine on the dmz subnet will see the inside host as it's native IP address.

You must be running 7.x or 8.x code on this ASA so make sure the following is also in place.

make sure you have the command "nat-control" in your config, otherwise the above config
commands will not work. Nat-control is disabled by default. Also, if you want NAT overload on the outside interface the above config will need some additional commands.

for instance;

nat (inside) 1
global (outside) 1 interface

Also, do not forget to add appropriate access-lists if outside initiated traffic is allowed in.

Here is a good doc:
