Yes, it was a small part of my pf.conf. Anyway i'm trying on another machine
with a much smaller configuration with the same results. I think it should be
enough for bruteforceblocker to work
table <bruteforce> persist file "/var/log/bruteforce"
set block-policy return
set loginterface bge0
scrub in all
# filter rules
block in log quick inet proto tcp from <bruteforce> to any port ssh

Yes, they display as expected
No ALTQ support in kernel
ALTQ related functions disabled
scrub in all fragment reassemble
block return in log quick inet proto tcp from <bruteforce> to any port = ssh

I cannot figure what's the problem, the bruteforce table remains clean after
the tests, but the bruteforce blocker is running in the system apparently
whithout any problems as i have checked with ps.
