Huh, never heard of it! from what I gathered from the website its a central VPN? Wouldn’t that be overkill for a homelab scenario? Thanks for your response!

Thank you for not only taking the time to answer but also adding quite useful resources. I will look into it!

That seems to be the only viable option. Someday I need to build something like this myself.

The problem is probably a legality thing. In Germany for example AFAIK people need to be told they are recorded and must accept to this. So by implementing such a feature, you need to adhere to local laws, which differ from country to country and may make it way to complex and dangerous to implement.
