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
