Journey into self-hosting
So, I have a rpi4b that's currently running a VPN for family abroad. I'm just finishing setting up Ubuntu server 24.04LTS(I have limited number of USB sticks, and the largest is only 8gb, so this choice was one of size, I can go into ones I had considered before) on an old laptop. For my small business I've also bought a domain for a work email, and eventually a website both are/will be hosted externally as I don't want to faff about with securing those aspects on my home network. The VPN though, that is currently pointing to no-ip dns service, and I want to migrate that to both the laptop and my own registered domain. What's best practices here? I do need the VPN to exit through to my network, so that my MiL can watch UK streaming from abroad(TV licence shenanigans).
VPN needs to come in from my domain IP, but exit from my network. What network security best practices should I be implementing?
Best practices comes down to what you do or do not want the VPN clients to access. This mostly comes down to routing and firewall rules.
So, what should your users have access to?
Also what is the vpn?
Some users just need to be able to exit my home network.
I would like to, maybe, in the future have a file server/jellyfin, have access to other devices on my network and if I'm somewhere with low enough latency stream games off steam.
Just wanted to say, thanks for asking me for further details. You could have been a dick about my unclear initial post, and I appreciate your just picking away at it until I was a bit more specific about what I was actually asking for.
If this was reddit the whole thing would've been a fair bit more hostile.
You did not answer what VPN tech you are using.
Without that knowledge i would recommend setting up tailscale and having your users use that. If you want to be fully self hosted you can also run Headscale as the control plane instead of relying on Tailscales own service.
I recommend tailscale as it is very easy to grant a user privileges to ONLY use an endpoint as an exit node but also grant access to any other endpoints as needed (such as your future jellyfin server) via theor ACLs.
Ah, yeah, sorry. Currently I'm using WireGuard, but I'm open to using something else.
I'll have a look at Tail/Headscale, this was very informative, thank you very much.
In the scope of wireguard it'll just be a matter of you building appropriate firewall rules.
Since you want their internet traffic to go through you then i assime you're effectively pushing a 0.0.0.0/0 route to your clients. You then need to add firewall rules on your server to block traffic to its local subnet and in the future allow traffic to only your jellyfin server.
This is also pretty simple and nothing wrong with that setup.
Thanks so much for taking the time to give me this info.
