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

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

I currently have site to site set up and working using kmod-wireguard on the UDMP, (https://github.com/tusc/wireguard-kmod) and a netgear running DDWRT on its native wireguard client.

https://github.com/tusc/wireguard-kmod maybe this can help? I’m not certain though

Just make sure you use the latest github release, instead of the one in the article since it was written in December 2021, so replace the link with the latest from: https://github.com/tusc/wireguard-kmod/releases

wireguard has been avaliable for quite a while. Check it out here. Also if you are inclined there is a redditor by the named u/peacey that developed split-vpn. Which is pretty cool. Although not official it works great imo.

Ah, you too have a UDM. I don't know if you knew it was an option, but if you already have the udm-utilities boot loader set up ( https://github.com/boostchicken-dev/udm-utilities) , there is a kernel level wireguard model that you can install right into the udm. ( https://github.com/tusc/wireguard-kmod)

If you don't shy away from the CLI and know basic Linux networking, you can easily set up wireguard or openvpn on the UDMP, and even push traffic via VPN gateway selectively per client or VLAN.
