    Hello,

    the ISS RealSecure Network Engine has the
    possibilty to respond to detected attacks with
    a RST-TCP-packet (RS-Kill).

    my questions are:

    To which IP-Dest addresses RealSecure sends
    the RS-Kill (server or client or both) ?

    Which MAC-Src address RealSecure uses for
    building the RS-Kill (the own or faked for
    server, client (router)) ?

    If RealSecure uses the own MAC then you have
    false entries in the arp cache of router/switch.

    If RealSecure uses faked MAC for server or client
    then you have false entries in the bridging table
    of the switch.

    Exist any solutions for this (potential) problem ?

    Birk
