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
