Public IP Question

[Namekian]

I have five public IPs and one line comming in. Is using the secondary ip command the best way to set the port to be able to go out all five ips?

Ah...what are you wanting to do?

you mean to NAT from the internal side and have all 5 externals be used?

you need to do an 'overload' command on all 5 IP's

What if he wants a DMZ with his external address for web servers or what ever else. He wouldn't need to NAT to all 5 of his external addresses. He'd need to NAT to one and use the other 4 for external facing devices. I think we need more specific's to answer any questions.

What I am trying to do is set up a network that certain private IPs go out certain public IPs.
For instance:
192.168.1.2 goes out 1.1.1.1
192.168.1.3 goes out 2.2.2.2

I have a Cisco 2621 router and a Cisco 512 PIX Firewall.
The Cisco 2621 has 2 TI DSU/CSU ports and 2 ethernets. The firewall has 4 ethernets. I have ran into a problem with the TI DSU/CSU because the building has all of the offices connected to the same switch. Meaning I have to use one of my ethernet ports for the backbone.

This creates a problem. How would you all suggest I set this up like? I am not very knowledgeable on the Firewall, but as far as I know you can't assign one port on the Firewall to support 5 public IPs.
