Today in #FreeSoftwareAdvent, it's pf(4)

Having lived through several iterations of firewall management tools on Linux (and FreeBSD offers both IPFW, IPFilter, and pf in the base system), I've come appreciate the simplicity and declarative nature of pf.conf for my firewall management.

The only downside is the quirky syntax of pfctl(8) but I do like being able to run my rules through it to sanity-check them from vi/ed with

:w !pfctl -nvf -

before installing them.
