ARFNET2 deployment

After the disastrous ISP schism

Masterplan

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

Stage 2: new services

• IONOS VPS for mail
• Some new very safe services
• HE IPv6 tunnel
• Own authoritative nameservers for domain zone

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
