🧱 How to Install Pi-hole in Proxmox Using the Helper Script (LXC Method)

If you’ve got Proxmox running and you're not using it host a network wide AD block, what are you even doing?

Here’s a quick, no-BS guide to spinning up a Pi-hole container on Proxmox using the legendary Helper Scripts from tteck. It's fast, clean, and doesn’t involve fiddling with Raspberry Pi hardware.

🚀 What You’ll Need

• A working Proxmox VE setup
• Access to the Proxmox web UI
• A brain (just one)

🔧 Step 1: Open the Proxmox Shell

From the Proxmox web UI:

1. Click on your Proxmox node.
2. Click Shell.

🔗 Step 2: Run the LXC Helper Script

Go to https://community-scripts.github.io/ProxmoxVE/scripts?id=pihole

Copy the Bash Script

Paste into the Proxmox WebUI Shell.

This launches the interactive Pi-hole container setup script.

📦 Step 3: Configure the Container

You'll be prompted for a few choices. Here’s what to do:

• Container Type: Unprivileged (default is fine)
• CT ID: Pick a number not already in use (e.g., 103)
• Hostname: pihole
• Disk Size: 4GB+ is plenty
• CPU Cores: 1–2 is fine
• Memory: 512MB minimum (1GB recommended)
• DHCP/Static IP:
  • Choose static for best results
  • Enter your network info (IP, gateway, subnet)
• DNS: Use 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google)

Once confirmed, the script will create and configure the container automatically.

▶️ Step 4: Start the Container

If it doesn’t auto-start:

1. Go to your Pi holenode
2. Click on shell and paste the script below to set password
3. Run pihole setpassword

🌐 Step 5: Access the Pi-hole Dashboard

Once running, go to:

http://<your.container.ip>/admin

Log in with the password you set earlier.

🧪 Step 6: Set Your Router’s DNS

To apply Pi-hole network-wide:

1. Log into your router’s admin panel.
2. Find the DNS Settings.
3. Change the Primary DNS to your container’s IP address.
4. Remove or leave the Secondary DNS blank (to force all DNS through Pi-hole).
5. Save and reboot your router if needed.

🎉 Now every device on your network is using Pi-hole to resolve DNS—aka no more ads.

📈 Step 7: Confirm It’s Working

1. Visit http://<container-ip>/admin
2. Check:
   • Query logs
   • Blocked domains count
   • Client IPs using Pi-hole
3. Visit an ad-heavy website. You should notice... nothing. No ads. That’s the point.

🛠 Common Commands

Run these inside the container via shell:

✅ You’re Done

You just:

• Deployed a Pi-hole LXC container using one script
• Blocked ads across your entire network
• Used Proxmox like a real one

Clean internet, better privacy, and faster browsing—for free. Run it quietly in the background and forget about ad hell.
