PIX config question

["Mullen, Matt" <Matt.Mullen () globaldigitalmedia com>]

I only have 1 IP address from my ISP to use on the outside interface with
several clients on the inside.  I'd like to use PAT and specify the outside
interface as the global PAT address.  The software complains that my global
address conflicts with the outside interface address when attempting to
enter the global command.  Running ver. 5.1 of PIX.   Does anyone know of a
workaround?
