Okay, imagine this order:

1) Kernel starts
2) Network driver is loaded
3) Link is brought up
4) Interface is configured for IP (manually or via DHCP)
5) Firewall rules (ipfw or pf) are applied

Do you realise that between steps #4 and steps #5 there is a small
window of time where someone may be able to send packets to your machine
and get responses which would normally be blocked by ipfw/pf?
