ISpconfig on a hosted domain

Hi.
Im currently using ISPconfig on my webserver, but im not very happy with the config interface running on port 81.
Is there any way to host ISPconfig panel on a viritual domain at the same time as the port 81?
Like a copy of the site with the same sorce files.

BTW, ISPconfig is great

 

Take a look here: http://www.howtoforge.com/apache_reverse_proxy_ispconfig

 

Thx a lot

Gotta love ISPconfig and HowToForge
