Hello, friends.
So I've had my Pi-Hole setup for awhile now and it's great. I'd like to get Wireguard working with it, too, so I could browse the internet without loads of ads and trackers on the go.
However, small issue. All DNS traffic is forcibly routed to my ISP. If you need some details, I made this post on the Pi-Hole userspace.
I'm in America and my ISP is Spectrum. I was wondering if there's a way I could convince technical support to allow me to use a recursive DNS for privacy/security (more-so the second of the two) purposes, or if it is even possible to convince them to do this. I don't know if there's a specific number I should contact, email I should email to, or if I just have to endure the nightmare of getting passed around by customer service one Saturday. Any recommendations would be great.
An interesting note for anyone who's ISP is Spectrum, their DNS service, at least for me, uses OpenDNS with dnsmasq-2.57. That version of dnsmasq is over 10 years old. You see if this is the case for you with
dig CHAOS TXT version.bind @192.33.4.12 +short
dig CHAOS TXT version.bind @198.97.190.53 +short
Or something similar if those IP addresses are different for you. You can see that running those commands were a part of the steps I was asked to take in that Pi-Hole userspace post.
EDIT 1:
For those interested, here's some Github gist I found that shows how to use unbound + stubby for have a recursive DNS + DNS-over-HTTPS. There's also this from the DNS Privacy Project.
EDIT 2:
I seems that initial answer from the Pi-Hole forums was correct. There's probably something that was set in the firmware for the Netgear router that prevents me from setting up my own DNS servers. However, I notice on the router there's a "router mode" option that's on, which I can probably turn off, plug in my Pi to the Netgear device and have the Pi act as my router, thus letting me be able to use it as my DNS server as well. That or just suck it up and buy only a modem, not a router + modem combo.
Another option you can have, install the cloudflared service on your pihole and use that as a DNS server. Cloudflared can take DNS requests from your clients and then proxy those requests over DoT to an upstream server which supports DNS over TLS. I have used Google in the past for this. I had great success with this solution inside a corporate environment which blocked port 53 to all outside the network.
Could you elaborate on this please? Isn't cloudflared a tunnel INTO the machine running a service? Can you use the same tunnel for outbound traffic as well?? Where does the traffic end up? How does this work?
It was a while ago, so I can't remember exactly but there is a good article here The cloudflared daemon is setup to run a standard DNS server over TCP/UDP port 53 as normal. You configure the upstream DNS to be DoT based. The clients then send DNS requests as normal to the cloudflared service and then they convert them to DoT upstream and the response is then sent back to the client as a normal DNS response.
