Advice: accessing home network beyond home

Drudge@lemmy.world to Selfhosted@lemmy.world – 26 points –

Hi folks, I'm just getting into this hobby thanks to the posts in this community. So far, I've installed Ubuntu server 22.04 on an old laptop and got paperless working, and I'm pretty pumped. Now I would like to access it outside of my home network on my phone.

I have a Netgear R7000 with Advanced Tomato installed. Here's my plan, but I don't know if it would work... So I'm hoping for a peer review of sorts.

  • Get openVPN working on the router as a server.
  • make a certificate for my phone and use it as a client.
  • use my fedora laptop as the CA (?).

I think I need to use easy-RDA to make the keys and certificates...

Does that sound about right? It's this a good approach or is there something better/easier/more effective?

If there's a great tutorial around for accessing the home network externally, I'd super appreciate it. Would obviously prefer to do it myself and not pay for a service... I've been enjoying the learning experience!

I know it’s been mentioned before - but plain Wireguard is my way to go. KISS - keep it simple, stupid! setup might be a little bit of a learning curve, but once you got it for one device, others aren’t a big issue.

I had a CA, with OpenVPN, but that’s to much for a small setup like remote access to your home network.

Use it on iOS, Ubuntu and Windows to access my home services and DNS (Split-Tunnel).

It’s a pretty easy setup on OpenWrt. A quick look into the fresh tomato wiki tells me, that it shouldn’t be to complicated to achieve on your router (firmware). If you need help with setting Wireguard up, let me know, I’m happy to help out.

Big thanks to everyone that replied. Message received: ditch openVPN in favour of wireguard :-)

Uhm, status update: I just signed up for tailscale, and I'm able to access my home server after about 2 mins from first logging into the tailscale website. Wow...you guys weren't kidding 🙃

So what should I do next?

Nas, Media server, device auto backups to nas, game server, chatgpt instance, Lemmy instance, a website, wiki, nextcloud, pihole, or home assistant.

If you intend to collect/store data or make more servers, a nas would probably be a good idea to have.

Ok, I have an incoming Lenovo M93P SFF to upgrade my really old laptop as a server, so your list will be super helpful. Thanks!

You're mostly correct, but you don't need the laptop to act as a CA or anything. A CA is just a cryptographic key, you can generate them on the laptop, on the router, or wherever you want. All that matters is that the router and the clients agree on what the CA is.

Alternatively, you can port forward from the router to the laptop and run the VPN on the laptop itself. That will open you up to more VPN protocols such as WireGuard which is newer, works so much better, and a whole lot easier to get set up. That stuff just works. Or you can forward the SSH port, and use SSH forwarding using an app like JuiceSSH as the way to enter your network.

I can vouch for wireguard it's super easy to setup

Same here, but never tried tailscale or anything like that

So how does that work? Just using wireguard I mean.

Personally I use openmediavault (nas software) that has nice wireguard plugin and everything in UI. But you can use native wireguard app or pivpn for example.

  1. Port forward 51820 udp to your server

  2. Setup tunel and client on server

  3. Scan QR code with your client (android or whatever)

  4. and 3. has to be done for every new device

I personally am a fan of DIY when it comes to VPN. Check out Nebula. I'm working on building a Nebula-based network. Right now I'm using WireGuard tunnels. Pure WireGuard is diificult to scale but it does operate well scaled up.
