Welcome to your haven!

This is my little corner on the internet, were I write about my current projects, networking, security and everything else I encouner in my everyday work and studies.

Proxmox 2U Node Server Build

Sophos has a DMZ, a LAN, an HA, a WAN, and several normal Ethernet ports. I would like to set up the Ethernet ports together as a bridge.
