Pi-Hole-on-Google-Compute-Engine-Free-Tier-with-Full-Tunnel-and-Split-Tunnel-Wireguard-VPN-Configs VS wireguard-windows

Great starting point for me: https://github.com/rajannpatel/Pi-Hole-on-Google-Compute-Engine-Free-Tier-with-Full-Tunnel-and-Split-Tunnel-Wireguard-VPN-Configs/blob/master/CONFIGURATION.md

OG Github:

There might be many of guides and tutorials available for installing pi-hole in Oracle Always Free cloud. I have been using the installation script from here used for Google Cloud for 2 years with few modifications. Today I like to share it with this community. This is a straight script which sets up the wireguard & pi-hole and doesn't require terraform or docker.

I followed this tutorial and set up PiHole on GCP. It works, both with split tunnelling and full tunnelling. However, I need to have the VPN app on all the time for it to work. So I wanted to set it up behind my router and I found Option B on this website, which I couldn't make sense of it (I am mostly a novice). Is there a way to set it up with a TP-Link Archer A6?

Other way is that you can have a vps, setup wireguard server there (with pivpn) then connect your pc and phone to that server, I use this tutorial but might be confusing

I'm running an instance of pi-hole from a Google Cloud Instance. I followed these instructions Pi Hole Google VPS | Wireguard VPN, even they explain how to do it for free and give the reasons why is a good idea. You can start there. Even I was able to set the local router with OpenWRT and connect it to that instance using the wireguard vpn to only process the traffic from the DNS request of all devices at home. Let me know what you think.

Everything you need is here, host Pi-hole on Google VPS for free and connect to it for DNS https://github.com/rajannpatel/Pi-Hole-on-Google-Compute-Engine-Free-Tier-with-Full-Tunnel-and-Split-Tunnel-Wireguard-VPN-Configs

Create a WireGuard config in the AirVPN cliant area. Install the WireGuard app in Windows. Import the config file.

https://www.wireguard.com/install/ is the wireguard installer for windows. I'm not sure where it stores its configuration files on windows, but I'm sure that's documented on their website somewhere. Then you can configure it according to this wiki article https://wiki.archlinux.org/title/WireGuard (yes it's for Linux, but wireguard works basically the same whether on Windows or Linux)

It seems the current official WireGuard Windows client, version 0.5.3, hasn't been updated in quite some time now. The GitHub repo shows no changes this year.

Again, have you tried your configs on wireguard application (link below) https://www.wireguard.com/install/

If this [1] is what you are using then create an issue on Github describing your setup, the issue and detailed steps to reproduce it. It appears they have 43 contributors so hopefully someone will have ideas.
