Pi-Hole-on-Google-Compute-Engine-Free-Tier-with-Full-Tunnel-and-Split-Tunnel-Wireguard-VPN-Configs VS docker-ipsec-vpn-server

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

IPSEC-L2TP is built into everything. No clients required on Windows, Mac, Android, iOS, Linux, etc. Great Docker container for cutting through most of the difficulty here: https://hub.docker.com/r/hwdsl2/ipsec-vpn-server

e.g: https://mingheng.medium.com/how-to-setup-an-openvpn-server-with-docker-on-an-aws-ec2-in-15-minutes-50443bd31dff atau https://github.com/hwdsl2/docker-ipsec-vpn-server

I'm currently using hwdsl2's VPN Docker container on my server so that I can access my internal network resources while away from my home network. However, it seems that if I connect through my DuckDNS pointer, the connection takes a long time to establish (iOS/macOS will simply say "Connecting..."). I know that this would be a question to raise an issue about, which I did so here. In a nutshell, the developer of the container believes that it would be an issue on DuckDNS' end.

Setup your VPN (one image I found on hub.docker.com is https://hub.docker.com/r/hwdsl2/ipsec-vpn-server)

My suggestion: Don't open up ssh to the world, set up a vpn to your home network instead, then connect to your server just as if it was on the loc network. Here's a possible option to setting up a VPN using docker: https://hub.docker.com/r/hwdsl2/ipsec-vpn-server

I use this and it works very well for me
