How to redirect DNS request for just 1 LAN of 2

I’m fairly new to mikrotik and networking in general. I currently working with opendns for blocking some webpages in Subnet1 and leave Subnet2 with total access to the web.

I’m aware there’s is a solution on the wiki page of mikrotik, but that makes the redirection for every Subnet in mikrotik, not just the one I need.

If anyone is interested the wikipage : https://wiki.mikrotik.com/wiki/Force_users_to_use_specified_DNS_server

How can I redirect to a specific dns (208.67.222.222 - 208.67.220.220) for just one of the subnets, so it doesn’t work when they customize their dns in their computer?

Use what you found, only with additional src-address=/.

Works perfectly, thanks.
