I have played around with yunohost and other similar tools. I know how to open ports on router, configure port forwarding. I am also interested on hosting my own stuff for experiments, but I also have a VPN enabled for privacy reasons on my router at all times. If you haven’t guessed already, I am very reserved on revealing my home IP for selfhosting, as contradictory as it sounds.
I am aware that it’s better to rent a VPS, not to mention the dynamic IP issues, but here it goes: assuming my VPN provider permits port forwarding, is it possible to selfhost anything from behind a VPN, including the virtual machine running all the necessary softwares?

edit2: I just realized my VPN provider is discontinuing port forwarding next month. Why?!
Absolutely possible.
The key to simple self hosting is to have a dns record that points to your externally accessible IP, whether that be your real one or an external one hosted at a VPN provider.
If that IP changes, you’ll need to update it dynamically.
It’s becoming increasibly common to be a requirement to do so as CGNat becomes more widespread.
One of the newer ways to do that is with a Cloudflare Tunnel, which whilst technically is only for web traffic, they ignore low throughput usage for other things like SSH.
