## firewall ## firewall
Hetzner hosts have a firewall that must be configured from
https://robot.hetzner.com/server to only allow incoming ssh, http,
https requests for both IPv4 & IPv6. Each server has a "Firewall" tab
that provides control over this firewall.
The firewall applies to the VLAN too. The 10.0.0.0/8 source address
must therefore be allowed explicitly for IPv4 and that must be the
first rule of the firewall.
A template "k8s" was defined that can be used for sharing the same
rules between multiple k8s nodes.
