[OpenWrt Wiki] DNS hijacking
I've been hoping for a simple plug in or other means to block a tablet that seems to defy dns. I can't stop it from adding 8.8.8.8
There have been web articles from 2014 on the subject and they involve at best 2 pihole instances.
Is there anyone who might know a way to make a plug in that does this in a simple manner so others can plug in a feature?
It's already built-in, see DNS - GL.iNet Router Docs 4
Override DNS Settings for All Clients
But you won't be able to stop DoH nor DoT by using this method.
That shows up on a number of articles.
I assume the tablet uses a simple open dns to 8.8.8.8
I should say that I wanted adguard to remain on as that blocks one setting.
Seems simplistic.
iptables -I FORWARD --destination 8.8.8.8 -j REJECT
iptables -I FORWARD --destination 8.8.4.4 -j REJECT

Thank you for the links.
I didn't know about the built in dns options.
I was adding large data sets to the hosts file originally. At some point the file for some reason caused the router to slow to a crawl. I had to use vi to remove some. Guess I could make a new post on that.
