This homeserver is also my workstation/gaming/dev/everything.
I use QubesOS (an operating system based on the Xen hypervisor), and wrote some document about it: https://neowutran.ovh/qubes/articles/homeserver.pdf

Basically, I am hosting:

• DNS
• Matrix
• Email
• Jitsi
• Mumble
• Peertube
• Screego
• Nextcloud
• Searxng
• Tor
• Wireguard VPN
• Copy of wikipedia
• Personal website
  And others.

And for TLS, to have better security, and to avoid relying on third party company/providers, I am using DANE.

The "dane_without_root" is one of my projects and I am welcoming review / feedback on it

( I also posted about it on the QubesOS forum: https://forum.qubes-os.org/t/highlighting-neowutrans-technical-doc-about-qubes )
