We develop a tool to verify Linux netfilter/iptables firewalls rulesets. Then, we verify the verification tool itself.

Warning: involves math!

This talk is also an introduction to interactive theorem proving and programming in Isabelle/HOL. We strongly suggest that audience members have some familiarity with functional programming. A strong mathematical background is NOT required.

TL;DR: Math is cool again, we now have the tools for "executable math". Also: iptables!
