Pix port forwarding of one public IP to two internal IP's???

[fonegirl]

Hi,
I have a Pix router with five public IP addresses mapped to internal devices. I am tryiing to install a spam filter device in front of my Exchange mail server but because I only have 5 useable public IP addresses I would like to forward port 25 of the public ip 99.99.99.99 to the spam filter 169.1.1.1 and other incoming ports, i.e. 80 to the Exchange server 169.1.1.2.

Is this possible? And if so how do I do it?

Thanks in advance for sharing the info.
