Let me see if I understood...

You have as Apache(real IP) front-end to a several Apaches(RFC1918 IPs) in 
a DMZ ?

You can use the standard Apache Virtual Hosts plus Proxy/Reverse Proxy:

[in production httpd.conf fragment(domainnames changed)]
<VirtualHost *>
     ServerName www.domain.com
     ServerAdmin webmaster@domain.com
         ProxyPass / http://192.168.0.171/
         ProxyPassReverse / http://192.168.0.171/

</VirtualHost>

<VirtualHost *>
        ServerName www.domain2.com
        ServerAdmin webmaster@domain2.com
        ProxyPass / http://192.168.0.172:81/
        ProxyPassReverse / http://192.168.0.172:81/
</VirtualHost>

As You see You can also change port-number...
a read on a Apache Docs can explain in more details these examples...
