USE THIS WIREGUARD GUIDE INSTEAD: Full Tunnel or Split Tunnel IPv6 + IPv4 Wireguard VPN connections to an ad blocking Pi-Hole server, from your Android, iOS, Chrome OS, Linux, macOS, & Windows devices
Because Wireguard is available as a native kernel module in Ubuntu 20.04, this guide is going to get less attention from me. I have automated the setup of Pi-Hole and Wireguard VPN Client Profiles, and it is much simpler to get started with Wireguard.
Set up a Pi-Hole Ad Blocking VPN Server with a static Anycast IP on Google Cloud's Always Free Usage Tier
Configure Full Tunnel or Split Tunnel OpenVPN connections from your Android, iOS, Linux, macOS, & Windows devices
<img src="./images/data-privacy-risk.svg" width="125" align="right">The goal of this guide is to enable you to safely and privately use the Internet on your phones, tablets, and computers with a self-run VPN Server in the cloud. It can be run at no cost to you; shields you from intrusive advertisements; and blocks your ISP, cell phone company, public WiFi hotspot provider, and apps/websites from gaining insight into your usage activity.
<img src="./images/upfront-cost.svg" width="90" align="right">Run your own privacy-first ad blocking service within the Free Usage Tier on Google Cloud. This guide gets you set up with a Google Cloud account, and walks you through setting up a full tunnel (all traffic) or split tunnel (DNS traffic only) VPN connection on your Android & iOS devices, and computers.
Both Full Tunnel and Split Tunnel VPN connections provide DNS based ad-blocking over an encrypted connection to the cloud. The differences are:
- A Split Tunnel VPN allows you to interact with devices on your Local Network (such as a Chromecast or Roku).
- A Full Tunnel VPN can help bypass misconfigured proxies on corporate WiFi networks, and protects you from Man-In-The-Middle SSL proxies.
Tunnel Type | Data Usage | Server CPU Load | Security | Ad Blocking |
---|---|---|---|---|
full | +10% overhead for vpn | moderate | 100% encryption | yes |
split | just kilobytes per day | very low | dns encryption only | yes |
The technical merits of major choices in this guide are outlined in REASONS.md.

PiVPN Installation
PiVPN is an OpenVPN setup and configuration tool.
You cannot view the Pi-Hole web interface until you set up a VPN tunnel. After completing the PiVPN installation you will be able to access your Pi-Hole web interface using http://10.8.0.1 if you are using a UDP profile (desirable), or http://10.9.0.1 if you are using the TCP profile (less desirable).
Ensure you have elevated root privileges by running this command in the bash shell:
sudo su
Install PiVPN by running this command in the bash shell:
curl -L https://install.pivpn.io | bash
You will flow into a series of prompts in a blue screen. All of the default values are usually appropriate.
-
Choose OK or answer positively for all the prompts until you have to choose a VPN protocol. Your choices are Wireguard (default) and OpenVPN. Considering you have decided to follow an OpenVPN guide, you will choose OpenVPN here.
-
When asked to choose an upstream DNS provider, the default answer is Google. Choose Custom and set an IP Address of 10.8.0.1 <br><img src="./images/screenshots/custom-dns.png" width="284"><br><img src="./images/screenshots/custom-dns-ip.png" width="284">
The default answer to reboot is No at the end of the installer. It is fine to say No, we have a few more things to edit while we're logged in as root.
<img src="./images/logos/openvpn.svg" width="48" align="left">OpenVPN Configuration
Ensure you have elevated root privileges by running this command in the bash shell:
sudo su
Get into the openvpn directory by running this command in the bash shell:
cd /etc/openvpn
Server Configuration for VPN over UDP on Port 1194
Edit server.conf. I use nano to edit by running this command in the bash shell:
nano server.conf
Comment out the line which reads push "redirect-gateway def1"
so it reads as follows:
# push "redirect-gateway def1"
The longer the keep-alive interval the longer it will take either end of the openvpn connection to detect whether the connection is no longer alive. Because mobile devices often lose connectivity and regain it, lower values are desirable.
Comment out keepalive 1800 3600
and add keepalive 10 60
below it, so it appears as follows:
# keepalive 1800 3600 keepalive 10 60
Comment out the line which reads cipher AES-256-CBC
and add cipher AES-128-GCM
below it, so it reads as follows:
# cipher AES-256-CBC cipher AES-128-GCM
At the bottom of the file add the following lines:
# performance stuff fast-io compress lz4-v2 push "compress lz4-v2"
Press CTRL
O
to bring up the save prompt at the bottom of Nano, press Enter to save. Then press CTRL
X
to exit
Server Configuration for VPN over TCP on Port 443
Ensure you have elevated root privileges by running this command in the bash shell:
sudo su
Get into the openvpn directory by running this command in the bash shell:
cd /etc/openvpn
To accept incoming OpenVPN connections over TCP on port 443 we need a separate configuration file. We can clone our existing configuration as a starting point, by running this command in the bash shell:
cp server.conf server_tcp443.conf
Edit /etc/iptables/rules.v4. I use nano to edit by running this command in the bash shell:
nano /etc/iptables/rules.v4
Below the line which reads -A POSTROUTING -s 10.8.0.0/24 -o ens4 -j MASQUERADE
, add the following on a new line:
-A POSTROUTING -s 10.9.0.0/24 -o ens4 -j MASQUERADE
Press CTRL
O
to bring up the save prompt at the bottom of Nano, press Enter to save. Then press CTRL
X
to exit
Edit server_tcp443.conf. I use nano to edit by running this command in the bash shell:
nano server_tcp443.conf
Replace the proto udp
and port 1194
lines with:
proto tcp port 443
Edit the server 10.8.0.0 255.255.255.0
line to reflect an IP address of 10.9.0.0, so it reads as follows:
server 10.9.0.0 255.255.255.0
Edit the push "dhcp-option DNS 10.8.0.1"
line to reflect an IP address of 10.9.0.1, so it reads as follows:
push "dhcp-option DNS 10.9.0.1"
Comment out keepalive 10 60
and add keepalive 10 120
below it, so it appears as follows:
# keepalive 10 60 keepalive 10 120
Comment out fast-io
so it looks like this:
# fast-io
Press CTRL
O
to bring up the save prompt at the bottom of Nano, press Enter to save. Then press CTRL
X
to exit
Add the OpenVPN service on Port 443 by running this command in your bash shell:
systemctl enable openvpn@server_tcp443.service
Finalize VPN Confgurations on Server
Reboot the server by running this command in your bash shell:
shutdown -r now
<img src="./images/logos/pivpn.png" width="48" align="left">
Managing the PiVPN
Connect to the Pi-Hole server and set up an OpenVPN Client Profile. (You do not need to have elevated root privileges to do this.)
pivpn add nopass
Give your client profile a name. I like to use an alphanumeric string composed of the user's first name, and their device's make and model (no spaces and no special characters).
NOTE
Make a new client profile for every device. DO NOT share a client profile between two different devices.
This command will output a success message which looks like this:
======================================================== Done! mypixel3xl.ovpn successfully created! mypixel3xl.ovpn was copied to: /home/myusername/ovpns for easy transfer. Please use this profile only on one device and create additional profiles for other devices. ========================================================
To get the mypixel3xl.ovpn file to your phone it is easiest to maximize your SSH window and print the file to the terminal window, to copy & paste the output:
cat ~/ovpns/mypixel3xl.ovpn
Press CTRL
-
until the screen zooms out to a point where you can see the entire ovpn file printed on the screen. The first line will have the word client
and the last line is </tls-crypt>
. Highlighting this entire chunk with a mouse will cause a scissor icon to appear in the middle of your SSH window, this means this selection has been copied to your clipboard.
Saving a Split Tunnel VPN Client Profile for UDP VPN Connections on Port 1194
Paste this into your favorite Text Editor and save the file with a name that is clear: mypixel3xl-udp-1194-split-tunnel.ovpn
Around Line 12, edit the line which reads cipher AES-256-CBC
and change it to read:

Verify Everything Works
Test your Full Tunnel VPN
You do not need to perform this test if you are using a Split Tunnel to access only the DNS over VPN.
Go here: https://www.google.com/search?q=what+is+my+ip
You will see your IP address displayed very prominently at the top above the label: Your public IP address
If you see anything other than the External IP Address of your Google Compute Engine Virtual Machine, then you do not have a Full Tunnel VPN.
If you see an IPv6 address while connected to the VPN, then you have a big problem.
Example of an IPv6 address: <br> <img src="./images/screenshots/your-public-ip.png" width="235">
You can do some further troubleshooting by visiting: https://www.whatismyip.com
If you see no IPv4 address, and a public IPv6 address identical to the one from the Google search result earlier, it means your tunnel is not processing any IPv4 traffic, and you are going out to the Internet over IPv6 directly.
This typically means you have a problem with your server configuration and client configuration files.
Test for a DNS Leak
If DNS lookups are not happening exclusively over the VPN connection to the Pi-Hole server, then you have a DNS leak. A DNS leak will result in ads appearing.
In the Pi-Hole Web Interface at http://your-external-ip/admin/settings.php?tab=dns
choose just one DNS provider. The two Google IPv4 DNS servers will give you the highest performance. For our test, we will deselect the Google IPv4 DNS servers and choose the 2 Cloudflare DNS servers.
On your device, go to https://www.dnsleaktest.com/ and click the Extended test button. On the table in the next page, every single row must say "Cloudflare". If you see any IPs that do not belong to Cloudflare, you have a DNS leak. This typically means you have a problem with your server configuration and client configuration files.
Turn your VPN off and try the Extended test again, you will see your default DNS servers as defined by your Internet provider or your Router.
Once you are done testing, only use the Google IPv4 Upstream DNS Servers if you want the fastest DNS resolvers for your Pi-Hole. You can use any of the other Upstream DNS servers if speed is not your number one requirement.
Test the Ad-blocking
The majority of in-app advertising should be eliminated, on your mobile devices.
A quick test page to verify if your ad blocking is working: https://ads-blocker.com/testing
Five Filters had a great page, which appears to have stopped working as of July 2, 2020: https://blockads.fivefilters.org/
<img src="./images/logos/firewall.svg" width="48" align="left">Firewall
If you do not wish to expose unused Ports in the firewall, review your Google Cloud Firewall rules:
- Log into Google Cloud Console: https://console.cloud.google.com/
- Ensure your Project is selected in the blue bar at the top (next to the words "Google Cloud Console); by default it should be
- Click the Hamburger Menu at the top left, click VPC Network and click Firewall Rules
- Click default-allow-rdp in the table
- Click Edit at the top of the page
- Click Disable Rule above the "Save" button to reveal a radio button group
- Select Disabled
- Click the Save button
- default-allow-rdp is not necessary, because your Pi-Hole is not running on a Windows server and there is no service running on Port 3389
Firewall rules that are inconvenient to disable:
- default-allow-ssh should really only be open to Google's private network, alas they leave it open to the whole world by default. Nobody can successfully brute force their way into your server on Port 22, because it's not secured with passwords. It is secured with keys. If you disable this rule, you will not be able to use the browser based SSH interface in the Google Cloud Console until you re-enable this rule.
Configure automated Pi-Hole updates and scheduled reboots
PiVpn enables automated security updates of your Pi-Hole, but it won't restart the VM if the update requires it. Restarting the VM would require SSH'ing into it and restarting it if required. To remove that step, let's use a daily cron job to check to see if a restart is required and restart the VM as necessary.
To do that, let's add a new file to /etc/cron.daily/
called zz-restart-if-required
using the following command sudo nano /etc/cron.daily/zz-restart-if-required
. In nano, add the following lines of code which check to see if the reboot-required token file is present, restarting the VM if so:
#!/bin/sh
if [ -f /var/run/reboot-required ]; then
/sbin/shutdown -r now
fi
Files stored in /etc/cron.daily/
will only run if the permissions are configured to allow that, so we need to change the permissions to allow that file to run. To do that, execute sudo chmod 755 /etc/cron.daily/zz-restart-if-required
.
Similarly, Pi-Hole gets updated from time to time. Let's automate installing those updates as well. To do that, let's create a file using sudo nano /etc/cron.daily/update-pi-hole
and add in the following chunk of code:
#!/bin/sh
/usr/local/bin/pihole -up
We need to change its permissions so it is executible sudo chmod 755 /etc/cron.daily/update-pi-hole
.
If you're curious when they will run, Stack Exchange has a great Q&A for you.
