Hey everyone, I wanted to ask for some help regarding my DNS setup and for routing requests to my selfhosted services.

Currently I use Pi-Hole as a DNS server with my routers default DNS server as the upstream server. This allowed me to define local DNS entries using Pi-hole and route my requests to these domains directly to my local services. For example I bought a domain a while ago and in preparation for setting it up, I had it entered as a local DNS entry pointing directly to my servers IP address.

Earlier today I finally got around to setting up a cloudflare tunnel to expose one of my services to the outside world using the domain I bought. Ever since I did that, all requests to that domain seem to exit my home network, go through cloudflares network and then return through the tunnel, even though I have a local DNS entry for that domain name.

What I would prefer is for the request to be routed directly to my server instead, since I am in the same network already. Since my DNS server is the Pi-Hole, I figured this should happen automatically.

Is there an issue with my Pi-Hole setup? If there is any information missing I'll be happy to provide it. I wasn't sure what information I could safely post here.

Solution

I think I managed to fix the problem. After enabling the option Never forward reverse lookups for private IP ranges in Pi-Hole and clearing my DNS cache again, nslookup only returns local IP addresses instead of the IPv6 address of two cloudflare servers.

I think I fixed the issue by enabling the Never forward reverse lookups for private IP ranges option in Pi-Hole. After that I flushed my dns cache again and called tracert for my domain name. I only get one hop directly to my server now. nslookup also shows only local addresses now.
