Not only does this take time and hence slow down the page but also the result may be that we get a totally ad-overloaded page. Your browser does the same with every single element in that page, looks it up in DNS and then requests it. But – at the same time – and that concerns the first use case – there are also commercial ad sites embedded. Inside that document there are usually many other references to other sites or elements, such as text or pictures. Once the browser knows the IP address, it can then make an http or https request to that address and gets back an html document. DNS does pretty much the same with IP addresses. You know the name and the city of the person you want to call and you can look up the phone number and then dial it. It’s kind of like looking up a phone number in a phone book. How does that all work? When we browse to a web site like let’s say, then the browser would first query a DNS server (DNS is short for Domain name system) in order to find out what IP address has. And the second use case is parental control. There are many ways to do that.īut first - why would we want to filter DNS? I can mainly see two use cases for this – the first one is removing or at least reducing ads, trackers and cookies. And – guys – we will not so much look into how to install or configure PiHole or adguard home – there’s many videos about this – What most people seem to struggle with is rather how to integrate in their networks and where to redirect IP traffic for DNS filtering. Many thanks.Today we’re going to talk about DNS filtering. Here’s the breakdown of this episode in case you want to skip or fast forward. We will have a look into 4 options, using DHCP option 6, the DNS Forwarder option, iptables filter rules on port 53 as well as running AdGuard Home directly on an OpenWrt Router. the redirection of DNS traffic to the Pi-hole or AdGuard Home machine. The main challenge for many people is the integration in the network, i.e. Privacy and protection of your data in the internet, blocking ads and the use of DNS White Lists or Black Lists. Those are two use cases for ad blockers and DNS Filters like AdGuard Home or Pi-hole (R). Though, it should actually be possible to write onto the USB drive using the path /mnt/sda1/: cd touch echo "look, i can write a file onto the usb drive" > cat /mnt/sda1/test.DNS Filtering - no more ads with Pihole or AdGuard tar.gz file onto the USB drive as intended but on the router's internal storage, which doesn't have sufficient capacity to actually store that file. The error arises because curl doesn't download the AdGuard. Starting AdGuard Home installation scriptĬurl: (23) Failure writing output to destinationĬannot download the package from into AdGuardHome_linux_mips_ Then, I ran both of the scripts routerDNS.sh worked fine, but installAGH.sh spit out these errors: InstallAGH.sh: # grab and install AGH and install it in a custom directoryĬurl -s -S -L | sh -s -c edge -o /mnt/sda1/adguard I saved the contents of routerDNS.sh and installAGH.sh into 2 new files and set a custom output directory (according to this answer on another thread): Hi, I'm trying to install AdGuard Home on my Archer A7 running OpenWrt 22.03.2 r19803-9a599fee93, or rather on a USB drive plugged into the router, since it doesn't have sufficient storage capacities.įirst, I followed the Automount tutorial from OpenWrt. ![]() IMHO there's a big difference between simple and dumb. I searched on their github and saw others mentioning it, AGH response was basically 'we're trying to keep it simple' AdguardHome problem 3539. I also tried manually editing the YAML file but that just resulted in unable to login showing a pop 'network error' when i tried to add more dhcp servers. They list all available ones for selection but only one selection can be active. Apparently you can only select one DHCP interface so if, like me, you have multiple vlans each with their own IP range then AGH currently cannot do this. I'll try this over the weekend otherwise my family will shout 'Dad what's happened to the internet'.ĮDIT: couldn't wait so i set this up in my testlab.Very soon into the configuration I noticed a 'feature' that renders AGH DHCP implementation not fit for my purpose. I will report back here if I find it steady enough for a daily driver. ![]() My setup will use latest stable openwrt 64bit, ipv4 (don't use ipv6), vlans and I'll try replacing both DHCP and DNS with AGH. I may fire up this setup on a raspberry, simply because it's easier to overcome problems than running on WRT32x where I always keeps one partition with the oem firmware, in case I brick. ![]() I'm running the latest edge and updates come through great.
