I have a small homelab that is not open to the internet. I am considering the following setup. Please let me know if there are any glaring issues or if I am over complicating things.
-
I want to setup a reverse proxy in the cloud that will also act as a certificate authority. (I want to limit who can access the server to a small group of people.)
-
I will setup a vpn from a raspberry pi in my home to the reverse proxy in the cloud.
-
The traffic will pass from the raspberry pi vpn to my homelab.
I am not sure if I need the raspberry pi. I like the cloud as the reverse proxy as I do not have a static IP. I would just get a cheap vps from hetzner or something like that.
How will running a CA limit access? eg. Do you want to do client side cert validation? That sounds like an overcomplication. Also not ideal to run a CA (have signing keys) on the proxy server.
Have you considered other approaches, such as Tailscale or Cloudflare Tunnels? I think you’re complicating things.
I’m not very familiar with either option. I’ll look into both of them. I think cloudflare tunnels have bandwidth limits though and I’ll be hosting jellyfin, so it might eat through the bandwidth quickly.
You can deal with the non-static IP by using duckdns.org
That sounds like a great plan, and a great way to learn how this sort of thing works.
it might be better to skip the cloud server and use cloudflare for dynamic dns. The standardized way to restrict access to websites is with client certificates or a basic authentication (user/pass) proxy. That would help avoid issues with internet traffic passing through the VPN accidentally.
Thanks! Last time I checked cloudflare had bandwidth limits. My primary uses for it may use a decent amount of bandwidth as I’ll be hosting jellyfin as well as my backup solution.
If you use tailscale you can omit the raspberry pi and tunnel directly from the reverse proxy to each server (could do this with wireguard but requires a little more setup). Also you can configure your cloud server as an exit node so that all traffic from your device go through it, sort of as a vpn service. It’s not as anonymous as a paid VPN service but at least you bypass the ISP or local wifi provider if you’re out and about.
Well if you don’t have a static IP, then your reverse proxy is going to break when your lease changes anyway. Not sure what your intended goal is for access and to what, but this is certainly a more costly and complex setup than needed for whatever it is.
The VPN should keep access to the homelab even when the external IP changes. Assuming the VPN connects from the homelab to the cloud. The reverse proxy would use the VPN local IPs to connect to services.
