Well my first reply is: setting up yor own router is like to learn driving with a touring car. You just need to know a lot to set up/handle everything properly. Its just not easy and in m opinion the most wrong point to start.
DNS-wise I would like to recommend something like pihole. To me it was my first thing I installed and used until this day and also the handling of DNS is quite easy. Maybe you should consider lerning other things before setting up your own router.


Isn’t fail2ban a possibility too? I created a filter for chatgpt and some others, and it feels like its working. My radicale server is my only free acessable service but it comes with a small webgui and so the bots showed up. I have no clue if the bot gets a fraction of your site each time it shows up, but seemingly the ban happens within 300ms when I remember correct. So it wouldn’t be that much of information…
When setting the retry to 1 it will ban at the first sight.
