When this field is set to Yes (as it is by default), any new virtual servers will have an `admin` entry added to their DNS domains, with the same IP address as the server's website. When `http://admin.thedomain.com/` is accessed, the browser will be redirected to Virtualmin on port 10000 of the same domain, to access the administration web interface.

If you want to use a different URL for Virtualmin access (such as one that you have an SSL certificate for) the redirect URL can be configured in the following URL for admin redirect field.
