Compared to working with iptables, PF is like this haiku: A breath of fresh air, floating on white rose petals, eating strawberries. Now I'm getting carried away: Hartmeier codes now, Henning knows not why it fails, fails only for n00b. Tables load my lists, tarpit for the asshole spammer, death to his mail store. CARP due to Cisco, redundant blessed packets, licensed free for me.
