I need a little help with this one.
TDS Internet (xxx.xxx.xxx.162/23)

pix pix pix (xxx.xxx.xxx.57/27)
Here's the set up. TDS line to the ASA. Behind the ASA are 3 different businesses, each with a Pix. I know, but it's how they want it. All 3 of the businesses host their own exchange. And 2 of them have test web sites they work on.
So, I'm pretty sure I have most of the configuration done. I was given 2 set's of IP's from TDS. The first is the WAN IP addresses, and 5 addresses all on the same subnet, along with the Default Gateway info for the Lan IP's.
I've configured the Wan IP on the Outside interface, and made the inside interface the Lan Default gateway IP. That will leave me the 5 ip's for the businesses. Now, here's where I'm getting stuck.
How do I route the IP's correctly, so, for example, when an Exchange request comes to one of the internal IP's, it gets routed there correctly?
I've set both of the interfaces on the ASA to be 100, and allow all traffic to flow between them, and have Natting disabled.
Has anyone else done a set up like this? Having a heck of a time finding some examples.
And no, before anyone asks, these guys are cheap. They insist on sharing the internet costs, being they're all in the same building.
