No, I only have dns configured for
http://www.domain.tld, not for admin.hostname.domain.tld. I would assume that
http://www.domain.tld would go to the virtual directory I added to ispcp and not to the admin page. If anything, the admin page would not resolve at all?? I am using a single external IP and would like to have admin.hostname resolve to ispcp and www. resolve to the virtual site.
Adding a host entry for admin.hostname.domain.tld pointing to my internal IP allows me to resolve to the control panel properly. I am not real concerned with external access to the panel now but I would like to get to the virtual site.
