I have a single ISPConfig server on a VPS with Debian Jessie, ISPConfig 3.0.5.4p8. 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.
if you need just one or two hostnames to be served from local network i would just use my /etc/hosts file and specify the names in there otherwise i think you need to do some tricks with split dns
Thank you for your answer. I have been able to make it work by having the same records on the local server but pointing to the the local IP. The downside is if I create something.example.com I have to create DNS on both servers. I found this link where the "second method" may do it: http://homepage.ntlworld.com./jonathan.deboynepollard/FGA/dns-split-horizon-common-server-names.html but I have not tried it yet. I have not been able to use the hosts file only - I have played around with dns-nameservers in /etc/network/interfaces and resolv.conf.
