As I start to host more and more services on my home server, my family and friends are interested in using some of the services I host as well. Up to now, all of my services have been internal-only, and my wife and I just use Tailscale to access everything. Getting others set up with tailscale isn’t an issue, but I can only have up to 4 other users before I have to pay to add more, and I have more than 4 people I would like to have access to some of the things I host.
Right now I’m using cloudflare tunnels to make some services available externally. I’m behind CGNAT, so I’m forced to use something like tunnels or similar. I’ve always read that if you are going to open things up externally to use a reverse proxy (which I use internally), but does this still apply with cloudflare tunnels? What else should I be looking at to make sure I have everything secured properly?
I rent a free tier oracle vm that does nothing more than tunnel traffic using GOST. Ports 80/443/25 and a control port that my homelab can connect to to establish the tunnel. No ports open at my house, public IP is the cloud VM, and the raw encrypted tcp traffic is tunneled through whatever NAT shenanigans my ISP might have and straight into Caddy within a docker (podman) network. I’m pretty happy with it and it works well!
It’s a single binary and can parse a config file or command line parameters. If I ever switch public VM providers, it’s a single binary download and a systemd service file. Switch my DNS records to the new VM and I’m completely done. And since my homelab establishes the connection to the VM’s port, I don’t have to reconfigure anything if I move buildings, switch providers, get stuck behind NAT, or can’t open ports.
Oh to be as smart as you.
