New blog post: PF Firewall on FreeBSD - A Practical Guide
After years of running PF across multiple FreeBSD servers, I've written up the patterns that work: macros, tables, brute-force protection, NAT for jails, and dual-stack filtering.
Covers everything from basic concepts to production configs, plus a sidebar on authpf for bastion hosts.
If you're running FreeBSD and want a firewall that's elegant, powerful, and actually understandable, PF is worth your time.
