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

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

Btw you can try this script..

If you want an easy setup I suggest using a script like this. Even a novice should be able to set up Wireguard in about half an hour - assuming they already have a DynDNS service set up.

Really depends on what you want to do. I run an Ubuntu server VM with Wireguard (my preferred script) , an openmediavault VM to take care or my NAS, HDDs (SATA controller is passed through) with mergerFS+Snapraid) and it also serves as my docker host, pihole VM for DNS (also allows you create your own, local DNS entries so you do not have to use the device's IP)

Yes, and no. Server security is a rather complex topic and covering it in a few sentences is impossible. Try to expose as few of your services as possible to the open web and also ensure they are well maintained - on your side (AKA update your stuff regular) and on the dev side. Seeing that the last github update was over ~6 months ago likely means there are unmitigated security risks. You can expect large projects like Plex, Nextcloud, Bitwarden(Vaultwarden), and others to be built well enough that they do not pose a significant risk. Anything else should only be accessible over a VPN. I am not talking about the commercial ones like PIA or NordVPN. These are mainly useful to circumvent geo restrictions, get better peering, and some other stuff. In terms of security, it does almost nothing despite what the ads claim. What I am talking about is running your own VPN server. Easily doable when you run a home server anyway by running a Wireguard script. By connecting to it remotely you will be able to access your home network as if you were at home although a bit bandwidth limited due to slow internet connections.

but if you don't then this is probably fine as well but I never used it https://github.com/angristan/wireguard-install

I personally use this script to setup a wireguard server. Doing it by hand is totally possible but this makes things a bit easier.

I do the same with Amazon and haven't had any issues. I run wireguard on an Amazon instance with the following script: https://github.com/angristan/wireguard-install
