Block /cpanel and port 2082 for some sites.

Hello.

I currently have some sites that want to access there cpanel.. and they find out they have cpanel by typing..

http://domain.com/cpanel

or

http://domain:2082

I do not want them to know cpanel is available for them.. is there a way to make the folder cpanel redirect to their homepage, the same with that port.

I tried using .htaccess redirect but no luck, just ignored it.

Thanks.
