pf problem, block .. os Linux

[Joakim Aronius <joakim@aronius.com>]

Hi there,

I used the following pf rule to block all Linux hosts from my sshd. It worked ok on 3.4 (blocked all password guessing attacks) but the rule doesn't trigger when i uppgraded to 3.6 (fresh 3.6 install, same old rules). 

block drop in log quick on $ext_if proto { tcp, udp } from any os Linux to any port ssh 

The rule sits before any 'pass .. ssh' rules. (and i added another block rule at the end, just in case.)

Any ideas?
