Help me get started with VPN

Submitted ⁨⁨10⁩ ⁨months⁩ ago⁩ by ⁨PlutoniumAcid@lemmy.world⁩ to ⁨selfhosted@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.
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
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.

If the access is just for you then don’t bother with VPN, just use Tailscale, and install the client on your other devices (they have clients for every OS).

This creates an encrypted virtual network between your devices. It can even enable access to hardware, like printers (or anything with an IP address and an Admin interface) by enabling Subnet Routing.

If you do need to provide access to specific resources for other people, you can use the Funnel feature, which provides an entrance into your Tailscale Network for the specified resources, fully encrypted.

And if you have friends who use Tailscale, using the Serve option, you can invite them to connect to your Tailscale network (again, for specified resources) from their Tailscale network.

  I second this. Wireguard, openvpn, various docker containers offering these, I’ve been through with them.
  
  The regular openvpn or wireguard tools are good if you only need a dumb von, but if you want some kind of special routing or overlay network, tailscale has just been so easy.
  
  I selfhost it completely too, using a headscale control server.

I’d use tailscale or zerotier, super easy use

- PlutoniumAcid@lemmy.world ⁨9⁩ ⁨months⁩ ago
  I used Zerotier before and I still use it now. It is also the solution I am now going to continue with.
  
  I wanted to try Wireguard to get away from a centrally managed solution, but if I can’t get it working after several hours, and Zerotier took five minutes - the winner is clear.

I chose wireguard implemented by pivpn (i like pi’s)

Wireguard app on phone and a quick duckduck will find you a script or app for your laptop. Connected to your home in seconds.

  PiVPN is elegant. Easy install, and I am impressed with the ascii QR code it generates.
  
  But I could not make it work. I am guessing that my Android setup is faulty, orrrr maybe something with the Pi? This is incredibly difficult to troubleshoot.

    As a side note i had to portforward in my router to make this work.

  Here is a script to easily install WireGuard and generate client config files for any server: github.com/Nyr/wireguard-install

I use WireGuard to access my home services and for net-forwarding when I’m outside.
To set it up, I followed this simple guide.
Make sure to choose a proper DNS if you want net-forwarding to work.

  Wireguard was really easy to setup on my ubuntu server. It took less than 15 minutes to get it up and running.

  I’ve heard very good things about wireguard-easy to simplify the config and management, too

rambos@lemm.ee ⁨10⁩ ⁨months⁩ ago
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.

I wanted to do something similar for a long time but somehow all my atempts failed. I tried the build in into a Fritzbox but my laptop never could connect. Later I tried the wireguard addon in homeassistant but same there.

  But does port forwarding work for you, can you access your servers from outside your network?
  
  If not, it’s probably carrier-grade NAT. There are several ways to fix this:
  
  Call your ISP and ask them to give you your own dynamic IPv4 address.
  
  Use a service like tailscale (also available in Home Assistant)

    Dynamic IP is one that changes. I think you meant static IP.

    Yes port forwarding with everything else works well, I have no problem with port forwarding, running a lot of services from home.

  You can self-host Headscale to cut the third party out of the Tailscale equation.
  
  source
  - stown@sedd.it ⁨10⁩ ⁨months⁩ ago
    If you’re going to do that you may as well cut out the extra server/service and run regular wireguard.

Personally I would have gone for OpenVPN access server on Debian. Fairly simple and well documented for those starting out.

I have used and worked with OpenVPN connect on android, PC and Mac.

  PiVPN offers both services, Wireguard and OpenVPN.
  
  What app do you use on Android? And on Windows?

  - teslasaur@lemmy.world ⁨9⁩ ⁨months⁩ ago
    OpenVPN connect on both. I load the .ovpn-file that is exported from the server and that’s it.

You would want to setup a VPN server on your linux server and vpn clients on android and laptop. I’m not knowledgeable enough to help, but you can look into wireguard

Check out Twingate. It’s super easy and with granular controls.
