pfctl -d
FreeBSD users sometimes compile pf from ports ( security/pf or sysutils/pf ). If the kernel is from a base system (e.g., FreeBSD 13.2) but the port installs a newer pfctl to /usr/local/sbin/ , a version clash occurs.
pfctl -d
Run:
# Save current active rules (compatible with running kernel) pfctl -sr > /etc/pf.current.rules
Next, flush all existing rules, tables, states, and counters from the kernel memory: sudo pfctl -F all Use code with caution.
Probably not. When the mismatch occurs, the kernel typically rejects the ioctl commands from the outdated pfctl , so the ruleset never loads. Your system may be running with no firewall rules at all. pf configuration incompatible with pf program version
: A recent OS update (e.g., FreeBSD 14.1 to 14.2) may have introduced new keywords or deprecated old syntax that the tool can no longer parse. Staged or Pending Updates

Ensure your entire base system is at the same release level. For example, on FreeBSD, check your version with freebsd-version -k (kernel) and freebsd-version -u (userland). pfctl -d FreeBSD users sometimes compile pf from
This error happens when the pfctl command-line tool parses a configuration file containing syntax, options, or features that the running kernel's PF module does not support. Why This Error Happens
Review your /etc/pf.conf against the official manual page for your specific OS version: man pf.conf Use code with caution. 4. Clear Static Rule Leftovers and Reload
