Title: NAT w/ Multiple External IP's

What is the best way to configure NAT on IPSO and IP330 so that I can have 1 real IP for the NAT pool, and several real IP's that map to different ports on the private network.

For example:

216.75.169.100  - Ethernet interface of router to internet
             |
             |
             |
216.75.169.101 - External interface of IP330
             |
192.168.1.1 - Internal Interface of IP330
             |
             |
             |
             |
      |--------------|
      |              |
Machine1     Machine2
HTTP 80         POP3 110
                     SMTP 25

Machine 1 External IP is 216.75.169.102:80 and internal IP is 192.168.1.2:80

Machine 2 External IP is 216.75.169.102:110 and internal IP is 192.168.1.3:110
Machine 2 External IP is 216.75.169.103:25 and internal IP is 192.168.1.3:25

Catch my drift?
Can this type of Port Address Translation be accomplished with Firewall - 1?

If not, my cisco box can do it, but how will the firewall allow the traffic in?
