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.
I’ve never heard of spectrum doing this. I think it’s an issue with your router. The steps you mentioned sound right, but I’m not seeing what you’re seeing. I usually try to look at the advanced mode, which might have more info.
You could contact Netgear tech support, or consult their manual. Have you made sure you’re on the latest firmware?
I tried to set the Pi-Hole as the DNS via the instructions here, and the exact settings for the Netgear router is under
Advanced -> Setup -> Internet Setup. Everytime I’ve set this, no hostnames can be resolved. I followed the Pi-Hole instructions to a tee, so I don’t know if I’d be missing something. Currently, the Pi-Hole acts as the DHCP server.Have you made sure you’re on the latest firmware?
I don’t even know how I would do this on this Netgear router. I see nothing in the settings to check for firmware updates, and I don’t recall seeing anything in the manual. I guess I’d have to call their tech support.
Ok, I see the problem. Your router needs an external DNS server for it’s internet setup.
You need to set DHCP to give your pihole server as the DNS to the computers INSIDE your network. It’s impossible for your router to use your LAN DNS server on the WAN port.
You might try flashing OpenWRT firmware if your router is supported. It allows changing DNS
or just use nextdns
I have spectrum and they don’t forcibly route anything for me.
You must have either their modem maybe? Or you have the DNS helper setting where if you mistype a url it redirects you.
Either way there is a way to disable it because it doesn’t happen for me and hasn’t in the many years I’ve had them across the country.
Hmmm then it’s something with the modem I have then. I can’t set the DNS address. It’s some cheap Netgear modem. If I go to
Advanced -> Setup -> Internet Setupand clickUse These DNS Serversand put in the address for the Pi-Hole, it prevents me from doing so.I think you mean router, since you would most likely not set DNS on a modem (unless it’s a combo) — but yes I would look into getting something better that you have more control over.
Edit: gotta love new Lemmy clients that spam comment replies 🤦♂️
It’s a combo. Most are these days, I believe, but I know Spectrum is weird and will give you a router AND modem if you just buy it through them. What device would you recommend? I don’t want to buy one just to find out I can’t set the Pi-Hole as the DNS server on a new one.
You just need to tell them you want a modem only, no router.
I’m running an Asus rt68ac with Merlin firmware. Which is nice because I can force all dns through my piholes. Even the hardcoded stuff like the iot devices.
I would recommend putting that modem in Bridge mode and getting something like a TP-Link Omada device. I’ve had them for a while and have been really happy.
Seems like I could potentially get around my issue by taking the device out of this “router mode” setting I found and connecting my Pi to it via Ethernet cable and have the Pi be the router for my network.
EDIT: Actually, scratch that. I don’t think a Pi would be powerful enough to act as a router. Well, off to by a modem (not a combo) it is!
How has been your experience with spectrum? Thinking about switching ISPs.
They are better than Comcast but that’s a low bar.
Overall I get Gig speeds for $80/m which isn’t terrible and no data cap. My previous house AT&T fiber was the same cost but better. I don’t have a choice where I live now so it’s Spectrum or DSL
I choose not to open any ports to the Internet for security reasons. But use tailscale to allow access to my home network while im away. It was an easy setup and can put it on all my devices.
I don’t think there’s anything in the Pi-Hole VPN setup with Wireguard that says you need to open up port 53. In fact, in the Pi-Hole userspace you see so many people specifically saying to not open up port 53.
I use PiVPN (wireguard protocol) on the same pi I use for pihole exactly like this. Port isn’t forwarded, but I can split tunnel DNS for adblocking on the go and still ssh to my other server
Oh, your ISP is very shitty, just like mine! Mine even do deep packet inspection! My solution is by using several upstream DNS servers that listen on alternate ports (so the requests are not intercepted by my ISP), and using TLS and QUIC (can’t intercept it because it’s encrypted). Can’t use DoH though because my ISP somehow can make it timeouts most of the time.
My Adguard upstream DNS settings (Adguard is configured to try all of them at once and use the one that respond first):
tls://1.1.1.1
tls://1.0.0.1
tls://8.8.8.8
tls://8.8.4.4
tcp://9.9.9.9:9953
udp://9.9.9.9:9953
quic://unfiltered.adguard-dns.com
Why do ISPs put in the extra effort to make their service shittier? What benefit do they gain from forcing more load to their DNS servers?
This is purely a money move. They want to sell statistical data if I had to guess. I use DoT with Unbound because fuck Verizon.
My country has a national block list that must be followed by all ISP. Last year, they even went an extra mile to enforce the DNS hijacking at internet backbone level, so if any ISP neglect to do it, it’ll still get enforced by the national internet backbone.
My ISP is fully embracing this system, to the point of performing deep packet inspection to enforce the national block list. Any blocked domain will return an IP address containing a web page full of ads (basically saying that the domain is blocked, here are some ads instead)I guess it’s profitable for them to do this. They also blocked Netflix using this system for years until Netflix caved in and partner with the ISP to sell subscription (yay for no net neutrality I guess).
You would have to implement DNS over TLS. To do this, it’s probably easiest to use Unbound and a service like Cloudflare or OpenDNS upstream. Spectrum probably hopes to harvest your DNS traffic and monetize it or maybe they’re doing some preemptive sanitizing of your requests to prevent you from going to a bad site. Regardless, I am anti DNS highjacking. It’s wrong on many points.
