So I'm new in the OpenWRT and Mullvad communities, and basically I flashed my router with OpenWRT and install Wireguard on it and followed the Mullvad guide to set it up. I also used the appropriate DNS server which filters out explicit content. The thing is that some websites, even though they come under the adult category are not filtered and I would like to know if it is possible to block them as well as use Mullvad's own DNS server?
I looked up BanIP module on OpenWRT but I am not sure how it works on a Wireguard tunnel because it is currently not working. So if anybody has any idea how to block websites which are not blocked currently by Mullvad's own DNS blocklist, please help.
