Firewalls

FreeBSD supports 3 firewalls: IPF, IPFW, and PF. Some time ago
(perhaps years) I seem to recall some discussion that one or more of
those was better maintained and higher quality than the others. I
don't see any indications of this in the handbook. Several years ago
I needed to do traffic shaping and used IPFW with dummynet. It worked
but the need eventually went away. More recently I needed to
incorporate spamd which defaults to PF so I used that. However, now I
am back to needing traffic shaping again. I suspect trying to use
both PF and IPFW simultaneously will not be a good approach. In
addition, there now are instructions for using spamd with IPFW so it
appears that either PF or IPFW will do what I need. Is there any
additional information available to assist in selecting between
those? Thanks.
