How to make nat with PIX outside interface

[zaza230]

I have only one public ip adress, this ip address is already assigned to my
pix outside interface. I would like to use this address in my "global outside X.X.X.X " command to nat internal trafic with the PIX outside address. When I do that I receive an error signaling that there is an overlaping between my command and the pix outside interface ?
How can I do it ? thank in advance .

I believe PIX OS version 6.0 is the first version that allows you to use your interface IP for PAT (someone, please correct me if I'm wrong).

In any case, the command would be:
global (outside) 1 interface

(where 1 is your NAT process ID)

I think you also need a nat inside outside line after the global outside line.

tbissett is correct about the global command to configure the Pix to do PAT. There is no nat (inside,outside) command syntax. You're thinking of the static command. You need the following two commands to make it work:

nat (inside) 1 0 0

global (outside) 1 interface
