You are confusing SI with Packet Filters. The technologies are

and it is, also, important to understand this distinction as well.

I don't think I am "confusing" the two.  I am saying that I have seen
people use them and think they are secure when they aren't.  IPv6 is
going to make it a little harder for people to make this mistake (or
easier to make it, I haven't decided yet which way it will go) and you
will see more people purchasing equipment that does real state
inspection which is my reason for predicting an increase in firewall
sales.  They won't have that dynamic NAT that lulls some into a false
sense of security.

Also, I believe the "fire suit" approach will become more important to
people rather than the "fire wall" approach with IPv6.


That's a great way of saying "host based security". With mobile
Internet devices (smart phones, laptops (which outsold desktops last
year apparently) etc.) becoming the dominant Internet access device, I
think host based firewalling will become the primary "firewalling"
mechanism. Network located firewalls will perform a secondary and
assistant role, because hosts can't be sure they're there when the
hosts have wired, wifi, bluetooth etc. interfaces that can all be
actively connected to the Internet at the same time.

Mark.
