Pix 515 PAT Question

I am setting up a Pix 515 to a client that has cable Internet access. They have 1 IP address assigned to them that I will be using on the Outside (eth0) interface. I have researched PAT on CCO and other resources and it seems that I cannot use this Outside interface IP address in the PAT statement:

global (outside) 1 x.x.x.x . I get an error message that says, "The start and end addresses overlap with the outside interface address". How can I use PAT then?

Re: Pix 515 PAT Question

The syntax is:

global [(if_name)] nat_id {global_ip [-global_ip] [netmask global_mask]} | interface

so:

global (outside) 1 interface

Re: Pix 515 PAT Question

Thanks for the reply Jeff. So just the syntax:

"global (outside) 1 interface" tells the PIX to PAT using the the assigned IP address of the outside interface?
