HELP HELP So confused

Help me understand why I can not go out to the other sites.

For the first I created the virtual server apache then went into the home and say I loaded joomla and after I tried the site in the browser and I exit the installation I performed the installation and site work but can not do it with other sites if I go to https: / / within the panel virtualmin but if I try to do it with other sites can not log

Sounds like a DNS problem. Are you sure the registrar glue records are actually pointing the the Virtualmin server for DNS?

From what I understand I bind dns should not touch it because you should configure alone in automatic or not?
