I bought a copy of "The Book of PF" from @pitrh

It's the best and most comprehensive resource about the marvelous PF firewall that I've ever seen, and I've been using PF since the early days.

Amazing work!

It's available here on No Starch Press: https://nostarch.com/book-of-pf-4th-edition

I also recently wrote a practical guide on PF (https://blog.hofstede.it/pf-firewall-on-freebsd-a-practical-guide/) for anyone who wants to get started :-)

@Larvitz I just learned about authpf from your article. That’s very neat!
@bytex64 authpf is great for jump-hosts/bastion-hosts. I use it primarily on OpenBSD machines , that I expose to DMZ networks. Adds a layer of additional safety, when the PF rules are only applied afer a user log-in 🙂
@Larvitz @bytex64 I use it for several years on large systems for many users. It's great.
