To view the log file:
# tcpdump -n -e -ttt -r /var/log/pflog
Note that using tcpdump(8) to watch the pflog file does not give a real-time display. A real-time display of logged packets is achieved by using the pflog0 interface:
# tcpdump -n -e -ttt -i pflog0
# pfctl -f /etc/pf.conf Load the pf.conf file
# pfctl -nf /etc/pf.conf Parse the file, but don't load it
# pfctl -Nf /etc/pf.conf Load only the NAT rules from the file
# pfctl -Rf /etc/pf.conf Load only the filter rules from the file
# pfctl -sn Show the current NAT rules
# pfctl -sr Show the current filter rules
# pfctl -ss Show the current state table
# pfctl -si Show filter stats and counters
# pfctl -sa Show EVERYTHING it can show
