Access Web Site

I have a web site residing in dmz1. Public IP addresses are assigned to the servers in dmz1. From my inside host I can access the web site by typing in for the URL.

I want to change my IP addresses to private IPs in dmz1. When I do this my inside host can no longer access the web site by typing in They now have to treat the site as a intranet site by typing in the IP address.

Why is this happening and how can I use private IPs while still allowing internal host to type in to access the web site.

The alias command changes the IP address of the webserver in the DNS respons to its actual ip address. Cisco's website has an example configuration for alias at:

Thanks for your help.
