Why AdGuardHome is a Game-Changer
Comprehensive Protection: AdGuardHome functions as a DNS server that filters out unwanted content before it reaches your devices. By blocking ads, trackers, malware, and phishing sites at the network level, it provides a blanket of security across all connected devices—be it smartphones, computers, or IoT gadgets.
Ease of Use: With a user-friendly interface and straightforward configuration, AdGuardHome is accessible even to those with minimal technical expertise. Its compatibility with Docker simplifies the installation process, allowing for quick deployment on various systems.
Customization: From setting up custom blocklists to configuring client-specific rules, AdGuardHome offers a high degree of customization. This flexibility ensures that your network security aligns precisely with your needs.
Setting Up AdGuardHome with Docker: A Step-by-Step Guide
Deploying AdGuardHome using Docker provides a streamlined and efficient setup process. Below is a comprehensive guide to help you get started.
Prerequisites
- Docker Installed: Ensure that Docker is installed on your system. If not, download it from the official website and follow the installation instructions for your operating system.
- A Virtual Machine (Optional): While not mandatory, using a VM can isolate AdGuardHome from your host system, enhancing security and manageability.
Step 1: Disable Existing DNS Resolvers
Since AdGuardHome will take over port 53 (the default DNS port), you need to disable any existing DNS services to avoid conflicts.
For Ubuntu or similar systems:
sudo systemctl disable systemd-resolved.service
sudo systemctl stop systemd-resolved.serviceStep 2: Launch AdGuardHome in Docker
Run the following command to start AdGuardHome:
docker run --name adguardhome \
--restart unless-stopped \
--network host \
-v /path/to/adguard/conf:/opt/adguardhome/conf \
-v /path/to/adguard/work:/opt/adguardhome/work \
adguard/adguardhome--network host: Allows the container to use the host’s network stack, essential for AdGuardHome to handle DNS queries directly.- Volume Mounts (
-v): Persist configuration and work data.
Replace /path/to/adguard/conf and /path/to/adguard/work with actual paths on your system.
Step 3: Initial Configuration
Access the AdGuardHome web interface by navigating to http://<your_server_ip>:3000 in your browser.
- Setup Wizard: Follow the on-screen instructions to complete the initial setup.
- Admin Interface: Create an admin username and password.
- Listening Interface: Set it to
0.0.0.0to listen on all network interfaces.
Step 4: Configure Upstream DNS Servers
Proper upstream DNS servers are crucial for resolving domains that aren’t blocked.
- Navigate to Settings → DNS Settings → Upstream DNS Servers.
- Add reputable DNS servers:
- Cloudflare:
1.1.1.1and1.0.0.1 - Google DNS:
8.8.8.8and8.8.4.4 - Quad9:
9.9.9.9and149.112.112.112 - Tip: You can also enable DNS-over-HTTPS or DNS-over-TLS for these upstream servers to encrypt your DNS queries.
Step 5: Enable Encryption (DNS-over-HTTPS/TLS)
To enhance privacy:
- Go to Settings → Encryption Settings.
- Enable DNS-over-HTTPS and/or DNS-over-TLS.
- Provide a domain name and obtain an SSL certificate (you can use Let’s Encrypt).
Step 6: Configure Clients to Use AdGuardHome
You have two options:
- Network-Wide Implementation (Router Level):
- Set your router’s DNS settings to point to the AdGuardHome server’s IP address.
- This will route all network DNS queries through AdGuardHome.
- Device-Specific Configuration:
- On individual devices, set the primary DNS server to your AdGuardHome IP.
- Set a secondary DNS server (e.g., Cloudflare at
1.1.1.1) as a fallback.
Step 7: Real-Time Monitoring
AdGuardHome’s dashboard offers real-time statistics:
- Query Log: View allowed and blocked requests in real-time.
- Statistics: Analyze trends over time, including most queried domains and clients.
Advanced Features and Configurations
1. DHCP Server Functionality
If you need a DHCP server:
- Navigate to Settings → DHCP Server.
- Enable the DHCP server and configure the IP range, gateway, and subnet mask.
- This allows AdGuardHome to assign IP addresses to devices on your network.
2. Client Settings
Customize settings for specific devices:
- Go to Clients in the dashboard.
- Add clients by their IP address, hostname, or MAC address.
- Assign custom filtering rules or parental controls per client.
3. Custom Filtering Rules
- Block Specific Domains: Add domains to the Blocklists to prevent access.
- Allow Specific Domains: Whitelist domains that you want to bypass filtering.
- Import Blocklists: Use reputable blocklists like:
- StevenBlack’s Unified Hosts: Blocks ads and malware.
- AdGuard Filters: Specifically designed for AdGuardHome.
4. DNS Rewrites
Redirect domains to specific IPs:
- Navigate to Filters → DNS Rewrites.
- Add a new rewrite rule:
- Domain: The domain you want to rewrite (e.g.,
example.com). - IP Address: The IP address you want it to resolve to.
- Use Case: Redirect
localdomain.comto a local server’s IP.
5. Blocking Services
AdGuardHome can block entire services:
- Go to Filters → Block Services.
- Enable blocking for services like:
- Social Networks: Facebook, Twitter.
- Streaming Services: YouTube ads, Netflix.
- Adult Content: Various adult websites.
6. Encryption Settings
Encrypt DNS traffic:
- DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT):
- Provides privacy by encrypting DNS queries.
- Requires a valid SSL certificate and domain name pointing to your AdGuardHome server.
- Configuration:
- Obtain a domain and SSL certificate.
- Enable DoH and DoT in Encryption Settings.
- Configure clients to use DoH/DoT.
Troubleshooting and Tips
- Restarting Services: If changes aren’t taking effect, restart the AdGuardHome service:
docker restart adguardhome- Port Conflicts: Ensure no other services are using port 53.
- Updating AdGuardHome: Pull the latest Docker image and recreate the container:
docker pull adguard/adguardhome
docker stop adguardhome
docker rm adguardhome
# Rerun the docker run command from Step 2- Firewall Settings: Make sure your firewall allows incoming connections on necessary ports (53, 80, 443).
Why Proper Configuration Matters
Without correct upstream DNS settings and proper configuration, AdGuardHome cannot resolve DNS queries, rendering your internet unusable. Always ensure:
- Upstream DNS Servers are correctly set.
- Client Devices are pointing to the right DNS server.
- Encryption is properly configured if enabled.
Summary
Installing AdGuardHome is a powerful step toward securing your home network. By blocking ads, malware, and phishing attempts at the DNS level, you gain comprehensive protection for all your devices. The ability to customize filters, monitor real-time activity, and even manage DHCP services makes AdGuardHome a versatile tool in your network security arsenal.
Deploying AdGuardHome with Docker simplifies the installation process, allowing you to get up and running quickly. With proper configuration—including upstream DNS servers, encryption settings, and client customization—you can tailor the experience to meet your specific needs.
