AdGuard Home

This tutorial is a follow-up to the official Traefik tutorial. It will guide you through integrating AdGuard Home with your existing wg-easy and Traefik setup to provide network-wide DNS ad-blocking.

Prerequisites

• A working wg-easy and Traefik setup from the previous guides.

Setup AdGuardHome

1. Create a directory for the configuration files:

   sudo mkdir -p /etc/docker/containers/adguard
   

2. Create volumes for persistent data:

   sudo mkdir -p /etc/docker/volumes/adguard/adguard_work
   sudo mkdir -p /etc/docker/volumes/adguard/adguard_conf
   sudo chmod -R 700 /etc/docker/volumes/adguard
   

3. Create the docker-compose.yml file.

File: /etc/docker/containers/adguard/docker-compose.yml

services:
  adguard:
    image: adguard/adguardhome:v0.107.64
    container_name: adguard
    restart: unless-stopped
    volumes:
      - /etc/docker/volumes/adguard/adguard_work:/opt/adguardhome/work
      - /etc/docker/volumes/adguard/adguard_conf:/opt/adguardhome/conf
    networks:
      wg:
        ipv4_address: 10.42.42.43
        ipv6_address: fdcc:ad94:bacf:61a3::2b
      traefik: {}
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.adguard.rule=Host(`adguard.$example.com$`)"
      - "traefik.http.routers.adguard.entrypoints=websecure"
      - "traefik.http.routers.adguard.service=adguard"
      - "traefik.http.services.adguard.loadbalancer.server.port=3000"
      - "traefik.docker.network=traefik"

networks:
  wg:
    external: true
  traefik:
    external: true

Update wg-easy configuration

Modify the corresponding sections of your existing wg-easy compose file to match the updated version below.

File: /etc/docker/containers/wg-easy/docker-compose.yml

volumes:
  etc_wireguard:
    name: etc_wireguard

services:
  wg-easy:
    ports:
      - "51820:51820/udp"
    ...
    environment:
      # Unattended Setup
      - INIT_ENABLED=true
      # Replace $username$ with your username
      - INIT_USERNAME=$username$
      # Replace $password$ with your unhashed password
      - INIT_PASSWORD=$password$
      # Replace $example.com$ with your domain
      - INIT_HOST=wg-easy.$example.com$
      - INIT_PORT=51820
      - INIT_DNS=10.42.42.43,fdcc:ad94:bacf:61a3::2b
      - INIT_IPV4_CIDR=10.8.0.0/24
      - INIT_IPV6_CIDR=fd42:42:42::/64
    ...

networks:
  wg:
    # Prevents Docker Compose from prefixing the network name.
    name: wg
    ...
  ...

Start services

1. Start AdGuardHome:

   cd /etc/docker/containers/adguard
   sudo docker compose up -d
   

2. Restart wg-easy to apply changes:

   cd /etc/docker/containers/wg-easy
   sudo docker compose up -d
   

3. Navigate to https://adguard.$example.com$ to begin the AdGuard Home setup.

/// warning | Important: Configure AdGuard Home Web Interface Port During the initial AdGuard Home setup, on the page for configuring ports, you must set the Web Interface port to 3000. Do not use the default port 80, as this will not work with the Traefik configuration.

After completing the setup, the AdGuard UI might appear unresponsive. This is expected. Simply reload the page, and the panel will display correctly. ///

If you accidentally left it default (80), you will need to manually edit the docker-compose.yml file for AdGuard Home (/etc/docker/containers/adguard/docker-compose.yml) and change the line traefik.http.services.adguard.loadbalancer.server.port=3000 to traefik.http.services.adguard.loadbalancer.server.port=80. After making this change, restart AdGuard Home by navigating to /etc/docker/containers/adguard and running sudo docker compose up -d.

Final System Checks

Firewall

Ensure the ports 80/tcp, 443/tcp, 443/udp, and 51820/udp are open.

Optional: Optimizing UDP Buffer Sizes

AdGuard Home, as a DNS server, handles a large volume of UDP packets. To ensure optimal performance, it is recommended to increase the system's UDP buffer sizes. You can apply these settings using your system's sysctl configuration (e.g., by creating a file in /etc/sysctl.d/).

net.core.rmem_max = 7500000
net.core.wmem_max = 7500000

After adding these settings, remember to apply them (e.g., by running sudo sysctl --system or rebooting)
