Hi,
after so many attempts of unsuccessfully restricted and allowed specified
domain from accessing my vhost, I tried the firewall.  Firewall did not
work.  Not sure where I messed it up.  See below, port 80, REJECT ip_address
wasn't working.  That IP address was my laptop:

HTTP:

<Virtualhost *:80>
  DirectoryRoot ...
  ServerName terrynt.server.com
<Directory "/www/mysite/test">
  Options Indexes FollowSymLinks
  AllowOverride None
  AuthUser Basic
  AuthName "Enter Passowrd"
  AuthUserFile /path/to/.password
  Require valid-user
  Order allow,deny
  Allow from badguy.com
  Deny from ALL
 </Directory>
</Virtualhost>
