split horizon DNS on ispconfig

[bkilinc]

We host several web applications and development versions of websites in local server at office. DNS data is on another server outside of office, every server have ISPConfig 3 installed.

The problem is I cannot access office applications, when in the office, on the same network. All I see is the router administration screen. To access office applications I need to change hosts file of every client.

I learned that I need to define "split DNS" data for this. so it will point to different IP'si for clients in the same network and outside. Can I define this data with ISPConfig 3? If not how can I implement this, any clues will be valuable.
