Packet Filter (pf)

====== Debugging pf rulesets FAQ ======
  * Q: My traffic from xyz to abc doesn't get through, why?
  * A: Enable logging on all "block" rules and watch on $tcpdump -vvvnei pflog0 for packets related to this connection attempt.  Also keep an eye on $pfctl -si.

Note: I plan to flesh this page as questions pop up on the freebsd-pf@%%FreeBSD%%.ORG mailing-list.  Please free to do so, as well!
