Thanks, this actually aligns with an article I read last night, and I planned to try it this morning.
Unfortunately, setting 'Accept DNS Configuration' to 'Disabled' still allows ads to come through.
Would you mind sharing the rest of your settings, along with the Custom Configurations on the bottom?
What's strange to me is that I see you're using Port 1198, and I know that's the recommended setting, but it doesn't work for me, neither does 1197. I have to use Port 502, it's the only one that will allow a connection to occur.
