Help me get started with VPN (lemmy.world)

TLDR: VPN-newbie wants to learn how to set up and use VPN.

What I have:

Currently, many of my selfhosted services are publicly available via my domain name. I am aware that it is safer to keep things closed, and use VPN to access -- but I don't know how that works.

domain name mapped via Cloudflare > static WAN IP > ISP modem > Ubiquity USG3 gateway > Linux server and Raspberry Pi.
80,443 fowarded to Nginx Proxy Manager; everything else closed.
Linux server running Docker and several containers: NPM, Portainer, Paperless, Gitea, Mattermost, Immich, etc.
Raspberry Pi running Pi-hole as DNS server for LAN clients.
Synology NAS as network storage.

What I want:

access services from WAN via Android phone.
access services from WAN via laptop.
maybe still keep some things public?
noob-friendly solution: needs to be easy to "grok" and easy to maintain when services change.

Not expert, but basically you should port forward wireguard port 51820 to your server, install wireguard server, create client(s) and load QR code (or config) on android/laptop and you are set. Pi hole DNS and everything else should work just like when you are on home wifi.

You can leave your CF for public access, but do you really need PF 80 and 443 if you are using CF tunnels? (I thought you dont, but I never used CF. Feels like its more safe to hve CF tunnels if you dont need to PF, but you have a middle man you have to trust)

Thank you for providing specific steps that I can take! I will look into this.

No I do not use cloudflare tunnels, just regular cloudflare to publish my services to the whole world - which is a concern of course.

Going with a connection from my device via wireguard sounds like just the right thing to do.
