bruteforceblocker + PF

[Dave]

Hello,
    I've got bruetforceblocker going with pf, i just installed the port. My 
box is a 5.4 machine. I have it going on my lan server, which does ssh for 
my network, it's the box you'll hit if you ssh in as opposed to the firewall 
box. It's adding ip's to the table, but it's doing it staggeringly, i see 
activity in my logs where atempts are made and then the IP's keep coming 
back as if they're not being blocked.
Thanks.
Dave.
