[Private IP] Domain goes to shared IP

Hi,

I need some help. I have been successfully using Virtualmin (GPL) for the last few months, but something came up that I needed to switch from Debian to CentOS.

Everything works good on CentOS except that I cannot use any private IPs. Rather it seems that the domain goes to the default shared IP despite being assigned a virtual interface.

Please see attached images..

Image One.. The domain configuration page, it shows that the virtual interface is active.. http://img85.imageshack.us/i/98187460.png/

Image Two.. The 'IP Address Allocation' section does not show up, this is my first hint that something is wrong.. http://img525.imageshack.us/i/11841978.png/

Image Three.. The domain goes to the shared IP, which is a empty directory since my main focus is to get the major site up first.. http://img269.imageshack.us/i/37842111.png/

I spent the day trouble shooting this, and now I am out ideas. Any help will be GREATLY appreciated, I'm already past my deadline for bringing the site back up..

Thank you
