I understand. That is Turris OS 4.x, right?
There was a mistake in our defaults where these special zones kept being forwarded to ISP servers (only – not with different forwarding or without forwarding). The mistake was fixed recently on 5.x and 3.x versions; 4.x won’t get any updates anymore. 5.x seems relatively close to stable release; for details see Turris OS 5.0.0 is released in HBT
