In this talk we will be building a highly available firewalling gateway. It is not a lecture or talk, it's a hands-on workshop.

how to play:

  • Log into the wireless network "antareztest"
  • SSH to the gateway in that lan (192.168.1.254 or 192.168.1.252)
  • Login as "root" password "bier"
  • use "tmux a" to attach to the shared session
  • break things, discuss, fix things
