I recently installed the stock nvidia graphics driver on my debian lenny machine by using the nvidia original driver from their support page. Just installing the kernel sources and the driver shell script and executing it lead me to a running nvidia dual head system.

pflog0
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
# 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
