    Hi,

    if a FW is said to be a stateful firewall, then will
    it allow a TCP packet to pass through it(outbound), if
    i haven't sent a TCP SYN to initiate a TCP Session
    before sending this TCP packet?

    I heard that Statefull firewall won't allow any TCP
    packets, other than TCP SYNs to pass through it, if
    there is no session corresponding a TCP packet is
    maintained in FW's session table.

    and FW will create a new session only when it detects
    a TCP SYN.

    is this correct?

    comments plz.

    thank u
    Manoj
