I have been trying to get this to work, and either there is something wrong with the ipfw daq module, or I have something set up wrong.

I am using freebsd 7.3 amd64, IF_BRIDGE (yes, it works.. it used to work with snort 2.8.4 with inline patches.yes, freebsd fixed the problem with divert and if_bridge)

snort started:

 snort -dQv -c snort_test.conf --daq ipfw

snort_test.conf:

#config detection: search-method ac-bnfa
config detection: search-method ac-split
#config detection: search-method ac  max_queue_events 5

config policy_mode:inline

var HOME_NET [10.0.0.0/8]

alert icmp any any <> any any (msg: "ping testing";rev:1;sid:1)



ipfw:
00100     0       0 allow ip from any to any via lo0
00200 18464 2478940 allow ip from any to any via con0
09000  1352  113492 count ip from any to any
10000   850   71400 divert 8000 ip from any to any
65535  1224  102740 allow ip from any to any


what happens, is as soon as I put in the divert rule, traffic stops being passed.

it is in /var/log/snort/alert:

02/08-10:09:24.936282 172.70.2.56 -> 172.70.2.13
