Do you expect nftables changed since you asked a week ago?

I think that the point is not about the exact rule you previously used, but rather the fact that the syntax and process should be the same with a few minor modifications to use the updated DNS server.

Please try to use what you learned in the previous thread and see if you can adapt the rules. If you have problems, please show us what you tried and the let us know what happened.
