I need for our customers a bind9-service on the mikrotik router. I tried openwrt with metarouter. It is running, but I would ask if there is an easier solution to just provide full dns services on mikrotik devices. I only need zone forwarding to some windows ad servers. (RB1100 and RB2011)
Not 100 % sure but I do not think this can be done within ROS.
My guess is we won’t see it soon either. DNS can be very CPU intensive. With to much DNS config it would be easy to DOS or DDOS your router.
Best is to hold this separat from the router.
