NAT two external addresses to the same internal server

[seba]

I have a server behind a Cisco PIX. I want to publish that service as to different public addresses.

So, externally there will be queries to two different public IPs that should be redirected to the same internal Server

Public IP 1 (port X) ----> Internal Server (port X)

Public IP 2 (port X) ----> Internal Server (port X)

Is it possible.

How to do it?

I have already done it using a secondary IP address for the server and a static translation to that secondary IP address?

Is there any other solution??
