I have a single ISPConfig server on a VPS with Debian Jessie, ISPConfig 18.104.22.168p8. It works perfect and runs all the services, including DNS. I have a similar local server at home with no incoming ports opened. I want to configure that local server so that when I am using it as my primary DNS at home, it serves some of the sites from the local server instead. I am trying to archive this: From outside: example.com -> www.example.com (works) From inside: www.example.com -> www.example.com (outside) example.com -> example.com (inside) My external server's hostname is www.example.com and it hosts DNS for itself. My internal server's hostname is dev.example.com. I have tried to set up the local DNS for example.com like the external but with local IP's (exept www) The result is that - if there now is no local DNS for any domain on the VPS - it all points to the local server. After som Googleling I wonder if I need to set up forward zones in Bind or similar? I would be happy to get a push in the right direction. Thanks in advance.
