Mein Provider und Arbeitgeber stellt mir an meinem VDSL Anschluss eine Fritz!Box 7590 zur Verfügung. Diese ist aktuell noch im Router Modus. Die Fritz!Box macht auf deren WAN Seite DHCPv4 und DHCPv6 mit einer öffentlichen IPV4 Adresse und einem /56 IPv6 Prefix. Auf LAN Seite liegt ein privates /24 IPv4 Netz an.
Auf meinem Homeserver virtualisiere ich mit KVM Gäste und LXC Container. Ein wichtiger KVM Guest ist meine OPNSense.
The open internet is a great place to code, but sometimes you are sitting behind a great firewall in a corporate environment. Your are not allowed to just pull the hottest stuff from the internet, but have to go through an internal binary artifact repository like nexus or artifactory.

Traditional SDNs are complex, making them hard to deploy and troubleshoot. Calico removes that complexity, with a simplified networking model designed for the demands of today's cloud-native applications.
Unlike SDNs that require a central controller, limiting scalability, Calico is built on a fully distributed, scale-out architecture. So it scales smoothly from a single developer laptop to large enterprise deployments.
Defining secure network policy used to be reserved for skilled network engineers. Calico's powerful micro-segmentation capabilities build on a simple policy language that naturally expresses the developer's intent.
