Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

My firewall rules are:

00010      660      73050 allow ip from any to any via lo0
00011        0          0 deny ip from any to
00012        0          0 deny ip from to any
00013        0          0 check-state
00100      131       4192 deny ip from any to any via sis0 keep-state

and so on.

Why is the check-state counter always zero? I thought this rule should match for dynamic rules. And I am sure there are.
