Mid 2022, a friend of mine helped me set up a selfhosted Vaultwarden instance. Since then, my “infrastructure” has not stopped growing, and I’ve been learning each and every day about how services work, how they communicate and how I can move data from one place to another. It’s truly incredible, and my favorite hobby by a long shot.
Here’s a map of what I’ve built so far. Right now, I’m mostly done, but surely time will bring more ideas. I’ve also left out a bunch of “technically revelant” connections like DNS resolution through the AdGuard instance, firewalls and CrowdSec on the main VPS.
Looking at the setups that others have posted, I don’t think this is super incredible - but if you have input or questions about the setup, I’ll do my best to explain it all. None of my peers really understand what it takes to construct something like this, so I am in need of people who understand my excitement and proudness :)

I appreciate this thoughtful reply. I read it a few times, I think I understand the goal. Basically you’re systematically closing off points that leak private information or constitute a security weakness. The IP address and the ports.
For the VPS, in order for that to have no bandwidth loss, does that mean it’s only used for domain resolution but clients actually connect directly to your own server? If not and if all data has to pass through a data center, I’d assume that makes service more unreliable?
Your first paragraph hits the nail on the head. From what I’ve read, bots all over the net will find any openly exposed ports in no time and start attacking it blindly, putting strain on your router and a general risk into your home network.
Regarding bandwith: 100% of the traffic via the domain name (not local network) runs through the proxy server. But these datacenters have 1 to 10 gigabit uplinks, so the slowest link in the chain is usually your home internet connection. Which, in my case, is 500mbit down and 50mbit up. And that’s easily saturated on both directions by the tunnel and VPS. plus, streaming a 4K BluRay remux usually only requires between 35 and 40 mbit of upload speed, so speed is rarely a worry.
