Apache forward to MASQ machines ???

Hello,
I am facing a crisis. Please read on...

I am a running a Linux server which is connected to internet (i have only
one IP). I am hosting
some websites. However some sites need to run a few application servers
which linux do not support. Linux server running APACHE. MASQ Machines
running win2k with IIS.

I have:
A Linux server --> SWITCH --> MASQ Machines

What i want (the domain names are just examples):
1. www.sql123.com runs on MYSQL with PHP. --> hosted on linux server
2. www.coldfusion123.com runs on coldfusion for win2k with MYSQL. -->
hosted on win2k MASQ machine.

Is it possible for APACHE on Linux server forward TCP requests to win2k MASQ
machine (192.168.0.10) if user types in www.coldfusion123.com, and serves
requests if user
types in www.sql123.com ???

I know that APACHE supports virtual hosting in which different sites are
pointed to different directories on linux. But can it point to the IP of the
MASQ machines??

I have heard that mod_rewrite is able to do. Is this true? But I really wonder how because that would mean that internet users would be able to access my MASQ machines which are behind the linux firewall... duhhh, impossible or is it??
