This is probably dumb...

Hello, everyone. I think I have seen this before, but I can't remember. How do I force Sentora to open ONLY on a certain subdomain (ie: virtual hosts through appache?) (ie: instead of users being able to see the panel on domain.com i only want them to see it on panel.domain.com).

Further, can I change the logo? No offence, just want to make it more "branded" for my clients.

Thanks.
