Perhaps iam not explaining well. The server is now connected to Internet, thatís why I could retrieve from the repositories, but it is not reachable from the internet using neither hostname nor ip address. Now can access the ISPConfig3 webinterface with a PC on the same Network via https://192.168.1.100:8080
As I saw in other installation guide ď(http is not working at the moment). Log in as root. Later, when the nameserver and the dhcp-server are configured (and you are using them), you should connect via http://server1.example.com
(the connection will automatically be diverted to https) or https://server1.example.com
. This is why I try to make this setup.
