Theme night: Router-Firewall

by vimja on 2024-11-21

We invite you to the second theme night! This time, we are going to talk about router-firewall solutions.

  • Datum: Thursday, 28th of November 2024
  • Zeit: Starting 19:30, doors open at 19:00
  • Ort: At our Hackerspace (Zwyssigstrasse 45 in 3007 Bern)

After a short introduction to the topic, there will be a couple of lightning talks. These are short presentations with a maximum duration of 5 minutes. After a short break, we will then take a closer look at the topic in a discussion round.

The theme evenings are an open format to which everyone is invited.

On the subject

This time it's less about the hardware and more about the software solutions we use to firewall our (home) routers. There are numerous solutions and a wide variety of approaches: Various specialised Linux and BSD distributions such as PFSense or OpenWRT are tailored to such deployments and offer APIs and intuitive web interfaces for configuring the firewall. The use of OpenBSD with self-written packet filters (PF) requires more manual work, but improves on flexibility. If you run a traditional Linux distribution on your router, you have to choose between iptables, nftables and now eBPF.

But it's not just the choice of software that gives you a lot of freedom - the structure of the tables, chains and rules also gives you plenty of room to express your own creativity.

Call for participation

If you also want to give a lightning talk, you don't need to do anything except prepare your slides / documents. Registration is not required. However, we ask you to keep your talk short (approx. 5 minutes).
