If you build FreeBSD from source ("Source Upgrades"), you must ensure you ran both buildworld and buildkernel , followed by installkernel and installworld . Running a new kernel with an old "world" will trigger this exact PF error. Re-run your build chain completely to align the binaries. On OpenBSD pf configuration incompatible with pf program version
This is the most common cause. The pf syntax evolves. Features are added, deprecated, or changed between major versions of FreeBSD or OpenBSD.
