If you wanted to do that, wouldn't the firewall just need directed-broadcast left open or emulate similar behavior, or even turning ip unreachables back on?
Exactly my point in using the word "amplifier" earlier. No special config or sploit-du-jour required. The play-by-play below is even more complicated than the process.
Flooding pipes accidentally is easy enough. Now people are selling products to do it deliberately.
They'll be sorry.
Yeesh.
I saw a license plate this week (Virginia -IWTFM) I thought that was clever.
Nice. :D

Yes, lets allow the kiddies who already get away with as little work as they can in order to produce the most destruction they can, the ability to use these 'Security Systems' as a new tool for DoS attacks against their enemies.
Scenerio:
Lets say my name is: l33th4x0r
I want to attack joeblow.cable.com because joeblow666 was upset that I called his mother various inappropriate names.
I find IP for joeblow.cable.com to be 192.168.69.69
I find one of these 'security' systems, or multiple security systems, and i decide to forge a TCP attack from 192.168.69.69 to these 'security systems'.
These 'security systems' then, thinking joeblow is attacking their network, will launch a retaliatory attack against the offender, 192.168.69.69 thus destroying his connectivity.

Mmm. A firewall that lands you immediately in hot water with your ISP and possibly in a courtroom, yourself. Hot.
Legality aside...
I don't imagine it would be too hard to filter these retaliatory packets, either. I expect that this would be more wad-blowing than cataclysm after the initial throes, made all the more ridiculous by the nefarious realizing the new attack mechanism created by these absurd boxen. A new point of failure and an amplifier rolled all into one! Joy!
More buffoonery contributed to the miasma. Nice waste of time, Symbiot. Thanks for the pollution, and shame on the dubious ZDnet for perpetuating this garbage.
