ispconfig3 Multiple Sites (Domains) in one Server

[dcarlos]

I'm trying to figure out how to use ispconfig3 to host two different Sites (Domains) in a single Server.

First of all I should say I'm not a server admin expert

I can add the two Sites, for example:
www.mydomain1.com and www.mydomain2.com

However this seams to generate two equal VirtualHosts in the httpd configuration.
mydomain1.com.vhost:
...
<VirtualHost *:80>
...

mydomain2.com.vhost:
...
<VirtualHost *:80>
...
In apache one will overlap the other, right?
Am I supposed to use Virtual IP addresses to do this?

Shouldn't ispconfig3 use domain names in the VirtualHost directive instead of ip addresses?
If so we would have:
<VirtualHost mydomain1.com:80>

Thanks in advance,
duarte
