A homelab mini PC isolated from the internet but controlled remotely

A fresh Windows mini PC would sit in a homelab rack and run software that keeps contacting its maker’s server to check authenticity. The desired setup would block that PC from reaching the outside internet completely, so the software could never contact home.

  • The main computer should still control it with RustDesk or .
  • The core need is to block outside contact while allowing .
  • Using this to avoid software authenticity checks is a serious caveat.
