I have a (test ports) version of  and am trying to make sure 
ipfw/daq works.

I have never gotten this to work in the past, and am still confused.

did you find you needed the -Q in the command line?
(man page seems to say this is for iptables only)

did you find you needed this in snort.conf?
config policy_mode:inline

what sysctl's did you need to add to turn on ipfw filtering?

(sysctl -a | egrep 'fw|bridge')

this in a router mode? with an ip on each interface? or bridged? (with 
what ifconfig options did you use to create the bridge?
