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
