    Anything in that article in particular you were wanting to discuss?
    -that article does appear to be a little dated

    Nope, general observations, interesting specially about UDP and fragmented packet issue vis a vis router's SPI.

    From the article:

    ---------------------------------
    Fragmented packets cannot be analyzed by a conventional packet-filtering firewall, so the firewall passes them through, but then they are assembled at the destination host. In this manner the network attackers can bypass firewall defenses altogether.
    ----------------------------------

    This statement (and similar) appears in various articles talking about networks, and am wondering how this exploit affects the home user.

    regards,

    If we home users are important enough, and thankfully like myself, we really aren't high priority, we would be exploited for sure.
