Open Source Summit + Embedded Linux Conference Europe 2020

Linux networking has gone through many changes over the years, and the ip filtering subsystem is no different. From ipchains, to iptables, and now to nftables, which is quickly becoming the defacto standard for network filtering on Linux. This talk is intended to get users who have a basic understanding of networking an overview of nftables, why it's a major step forward, why it's taken so long, and to get attendees the basics (including examples) they can take to deploy their own network filtering using nftables. This is primarily targeted as a teaching and 101 level discussion, and to give attendees a starting point to go further from. Basic concepts like tcp/ip, udp, network flows and such would be good understandings to have coming in, but the topics will be touched on briefly.
