I was planning on filtering local and external IP’s, like technotim explains in one of his videos by using cloudflare as an external reverse proxy

I’m aware of this. There are a few services I expose, but most of them are local. I just wanted to make accessing local services a bit cleaner.

Will also take a look at the router DNS, thanks a lot!

Okay, I’ll start with configuring pihole for DNS. If I get it, I can just use that DNS and if I need to access a service external I need to register the domain with my registrar?

Thanks for the reply! I think I get it now.
