Port Forward Security & Alternatives
As other's have suggested, I use wireguard to get into these services. One other thing I would suggest though is to setup SSH with external access using port knocking along with SSH keys. That means if your VPN is failing for some reason you can at least diagnose it.

UFW setup for decent security
Sure, few links for when you dig in: http://iplists.firehol.org/, https://crowdsec.net/, https://www.zeroflux.org/projects/knock/, https://www.cipherdyne.org/fwknop/

Linux automated shutdown from windows batch file.
Maybe port knocking would work. https://www.zeroflux.org/projects/knock

SSH safety measure
I can recommend another protection method: port-knocking. For example with this excellent little helper: https://github.com/jvinet/knock
- knock: a "port knocking" daemon that grants access to services based on sequentially opening a series of network ports.

Fail2ban Sucks
sounds fun; i see the arch aur has a few options as well. have you tried https://www.cipherdyne.org/fwknop/ ?

Has anyone ever had their homelab or network hacked? What happened?
Yes that's the basic idea, i tried to use fwknop first but it didn't do what i wanted it to do so i made my own

How to securely enable SSH access to my home network?
Port knocking. Or better yet FWKNOP. I'm disappointed I don't hear people talk about it more. The port isn't even open until you give the secret combination of knocks on a large number of ports. There's much more to it. I recommend listening to Episode 865 ofSecurity Now.

Show HN: Knockles – eBPF Port Knocking Tool
> Is this approach used elsewhere?
Yes, or at least in a similar fashion. An alternative variant of port knocking is SPA (Single Packet Authorization). Often SPA protocols use UDP and contain within the body field an encrypted payload containing all the required data to authenticate and authorize a particular request.
There are multiple different implementations of SPA: OpenSPA [1] (full disclosure: I am the author of OpenSPA), fwknop [2] just to name a few.
SDP (Software Defined Perimeter) often builds upon SPA technologies in order to achieve a form of zero trust access.

I am currently re-writting the OpenSPA protocol (version 2) and I plan on playing around with eBPF as well, so thanks eeriedusk for paving the way :)

Who's Attacking My Server?
An upgrade to port knocking is Single Packet Authorization [1]. It doesn’t suffer from the observability, and other, problems of port knocking.

Or keep the port closed like I do with my ssh port and use fwknop to open the port only when needed.
