What is AdGuard Home?

AdGuard Home is network-wide software for blocking ads and tracking. After you set it up, it’ll cover all your home devices it even includes a parental control solution, just like a PiHole it acts as your home network DNS server and will block advertising on any site you visit.

This guide will get you set up with AdGuard and cover some basic initial settings, I recommend checking out the documentation for all the various features available.

Host vs Macvlan vs Bridge Network Modes

Host:

Host mode uses your NAS underlying network to run the containers network services, so it will be reliant on the NAS not using any of the required ports for the container. However, this makes it easy to set up, but you need to make sure no other service is using the required ports. All your clients will appear correctly as independent devices and stats.

Macvlan:

This gives you the benefit of AdGuard having its own IP address on your network, all clients appear with their real IP addresses allowing you to assign specific rules and give you some nicer stats just like Host mode. However, one downside is that your NAS will not be able to use AdGuard for DNS, due to the additional security features of Macvlan and its communication with its host. This is generally not an issue unless you wanted to use you AD blocking with Tailscale.

Bridge Mode:

The main benefit of Bridge Mode will be the ease of setup however you will find that all clients on your network will appear under the same IP as the Bridge 172.20.0.1. This won’t impact ad blocking, but it will mean you can’t apply device specific device rules etc.

Let’s Begin

In order for you to successfully use this guide you will need to check that your Router allows you to change your network DNS servers, this is usually found in the DHCP settings.

Please follow the initial guide below to get a restricted Docker user in place and then come back here

Folder Setup

Let’s start by getting some folders set up for the container to use. Open up File Station create the following.

Folders
/docker/projects/adguard-compose
/docker/adguard
/docker/adguard/work
/docker/adguard/conf

Container Manager

Next we are going to set up a ‘Project’ in Container Manager. Open up Container Manager and click on Project then on the right-hand side click ‘Create’.

In the next screen we will set up our General Settings, enter the following:

SectionSetting
Project Name:adguard
Path:/docker/projects/adguard-compose
Source:Create docker-compose.yml

Next we are going to drop in our docker compose configuration, copy all the code in from the appropriate version of the container you want to run below and paste it into line ‘1’ just like the screenshot.

What on earth is a Docker Compose?
Docker Compose allows us to define how Docker should set up one or more containers within a single configuration file. This file is yaml formatted and Container Manager uses the Projects feature to manage them.

Please note you will not be able to use Macvlan with a Bonded network connection e.g. ‘Bond0’. You will need to remove the bond in order to use this method.

Host Mode

        - subnet: "192.168.0.0/24"
          ip_range: "192.168.0.254/24"
          gateway: "192.168.0.1"

Bridge Mode

YAML
services:    
  adguardhome:
    image: adguard/adguardhome
    container_name: adguardhome
    volumes:
      - /volume1/docker/adguard/conf:/opt/adguardhome/conf
      - /volume1/docker/adguard/work:/opt/adguardhome/work
    ports:
      - 53:53/udp
      - 3000:3000/tcp
    security_opt:
      - no-new-privileges:true
    restart: always

If you are setting up the Bridge or Host Mode versions you can now press next and jump ahead in the guide to Web portal settings for Macvlan continue on below.

Settings Amendments for the MacVLAN

OK we now need to make some edits to the compose in order for it to work on your Network.

I have broken down the edits needed in this table it includes the line numbers and an explanation of what to edit.

SectionExplanation
Line 11
ipv4_address: 192.168.0.122
Change to the IP address you want to use for the container. Make sure this is available and not in use by another device on your network.
Line 21
parent: eth0
This defines the network interface the container should use, I have used eth0 which will be the first Ethernet port on your NAS. If you want to use a different port change it accordingly.

Note! If you have Virtual Machine Manager installed change this to ovs_eth0
Line 24
subnet: “192.168.0.0/24”
We need to change this in line with your networks’ subnet – in the example I have used 192.168.0.0/24. The super quick way to work out what to use is just take the IP of your NAS and change the final digit before the /24 to 0
Line 25
ip_range: “192.168.0.254/24”
This has to be changed to the highest available IP address within the range of your subnet. Again if your network is in the 192 range the final number used from the subnet above can be changed to 254 and added to this section.
Line 26
gateway: “192.168.0.1”
This will be the IP address of your Router/Gateway/DHCP Server

Once you have made the edits you can click ‘Next’

Web portal settings

You do not need to enable anything on the ‘Web portal settings’ screen click ‘Next’ again.

On the final screen click ‘Done’ which will begin the download of the container images and once downloaded they will be launched!

The image will now be downloaded and extracted. You should see ‘Code 0’ when it has finished.

You will now see your AdGuard running and should have a green status on the left-hand side.

You should now be able to access the web interface via

Macvlan = the IP you specified in the compose followed by the port 3000
OR
Bridge or Host = Your NAS IP followed by the port 3000

Initial Setup

You will now do some initial setup steps

Step 1 – click ‘Get Started’

Step 2 – You will be asked to choose the network interfaces AdGuard will listen to for DNS requests and the Web Interface. Leave these set to ‘All Interfaces’ but change the Port for the Web Interface from 80 to 3000.

You will notice the IPs highlighted in Red in the screenshot will be either 127.0.0.1 or 172.20.0.1 do not use these as suggested by the UI as they will not work.

Click ‘Next’

Step 3 – You will be required to set up a Username and Password to access the Web UI. Fill these in (You could follow the Vaultwarden guide to get a password manager setup if you don’t have one already)

Step 4 – Configure your devices

The DNS address to use on your device or router/dhcp server will be

Bridge Mode or Host Mode = IP address of your NAS
MACVLAN Mode = IP address you assigned in the compose file

The addresses shown on the final screen in Red may show different IPs use the one I suggest above.

Click on Open Dashboard and you will be taken to the login screen.

Now log in to your account.

Once your devices start to update with the new DNS server IP you will begin seeing traffic in your Dashboard. (This can take up to 24 hours)

From here you can set up some initial settings such as additional ‘Filters’ (blocklists) or define additional upstream DNS providers who handle the requests that make it past the filters in Settings > DNS Settings.

More settings can be found here

You are ready to roll 🙂

    When using Adguard with macvlan mode, entering just the ip gave me a connection error. I had to also write the port 3000 after the ip adress to get access to the adguard setup. I found this out by checking the pihole guide where the guides states that, among other things, a port was needed to access the page. That gave me the hint to try the same with adguard.

      Sometimes I feel like my WordPress install is haunted as I rewrote sections of both the AdGuard and Pi-hole guides last week to mirror each other and this guide seems to have all the edits apart from the end. What is weirder is that this guide did have the ports called out in the first place.

      Spooky..

      Will get it fixed again.

    Since setting up pihole is giving me some issues, I decided to try AdGuard Home instead.

    I get all the way through the process, until it’s time to use the AdGuard Home DNS addresses. I go into my router’s DNS settings and toggle Use These DNS Servers, but when I input the AdGuard DNS (127.0.0.1, 172.20.0.3) I get the following error: Invalid primary DNS address. Please enter it again.

    Nothing worth doing is easy, that’s for sure!

      I will make this part a bit more prominent in the guide, essentially if you are using Bridge Mode use the IP of your NAS for the DNS address and in MACVLAN mode use the IP you assigned.

      You will use the IP address you set for the MacVLAN IPv4 earlier in the guide or your NAS IP if you are using in Bridge Mode (In bridge mode the screen will show the docker IP don’t use that). It should be shown on the ‘Configure your devices’ screen as below.

      • Christopher Green Christopher Green

        Normally I’m pretty good at reading comprehension, but it’s so easy to overlook those little details! It’s working and once again, a million thanks.

        • Dr_Frankenstein Dr_Frankenstein

          No problem – I am currently making my back way through the guides with formatting and wording tweaks, so all feedback is welcome.

  3. Gabriel Gabriel

    I very much appreciate your site and guides and wanted to say Thank You beforehand.

    One question that I have when deploying the AdGuardHome using macvlan. Is there any difference on using the following for the network instead of what you used?

    networks:
    macvlan:
    ipv4_address: 192.168.0.129
    synobridge:

    VS

    network_mode: synobridge
    networks:
    macvlan:
    ipv4_address: 192.168.0.129

    • Dr_Frankenstein Dr_Frankenstein

      Hey either will work – there are different ways to specify networks in Docker this is the same 🙂

  4. futurepersonified futurepersonified

    i’m following the instructions for bridge mode and when i try to make a DNS rewrite in adguard so that i can access my NAS by going to “server.” instead of typing out the IP address, it doesn’t work. i have a feeling it has to do with the bridge network because adguard seems to not list my NAS IP address anywhere, only the bridge IP (172.xxx…) any ideas what could be wrong?
