  <h2 id="masterplan">Masterplan</h2>
  <p>Stage 1: very safe - Close all ports - Nuke (or stop) all old VMs
  (exclude OPNSense) - Make DMZ - Make new basic VMs (cloning deb12
  template) - Open basic ports</p>
  <p>Stage 2: new services - IONOS VPS for mail - Some new very safe
  services - HE IPv6 tunnel - Own authoritative nameservers for domain
  zone</p>
  <p>Stage 3*: finally - Another VPS in unknown provider for - Tor -
  Reverse-proxying the media library - PHP on main site with more web
  services from scratch, hopefully secure - More new services</p>

  <h2 id="masterplan">Masterplan</h2>
  <p>Stage 1: very safe - Close all ports - Nuke (or stop) all old VMs
  (exclude OPNSense) - Make DMZ - Make new basic VMs (cloning deb12
  template) - Open basic ports</p>
  <p>Stage 2: new services - IONOS VPS for mail - Some new very safe
  services - HE IPv6 tunnel - Own authoritative nameservers for domain
  zone</p>
  <p>Stage 3*: finally - Another VPS in unknown provider for - Tor -
  Reverse-proxying the media library - PHP on main site with more web
  services from scratch, hopefully secure - More new services</p>
