PF syntax varies significantly depending on the operating system flavor and version. A major source of this error stems from mixing OpenBSD-style syntax with FreeBSD-style syntax, or upgrading across major versions.

If you recently upgraded your kernel via freebsd-update or source compilation, the safest fix is a full reboot:

If this command works but loading the rules fails with the version error, the issue is definitely a kernel/binary mismatch. Getting Started - OpenBSD PF PF syntax varies significantly depending on the operating

The Packet Filter (PF) firewall, standard on OpenBSD, FreeBSD, NetBSD, and macOS, is a powerful tool for traffic management. However, users and administrators occasionally encounter a frustrating roadblock when attempting to load or modify rules:
