    I am not sure about the Pix, but Checkpoint running on Solaris or NT could
    have different timeout values based on the OS. Also the administrator could
    have modified the setting,  I know when we build firewalls, we modify the OS
    config to reduce the timeout in order to reduce number of concurrent
    connections.

    if checkpoint uses a 60sec timeout for establishing a 3way and PIX
    uses a 300sec timeout (which seems too large but it's all the info I could
    find on it)
    and Gauntlet uses ??? could you not just send
    the intial syn wait the timeout value then try to complete the handshake?
    After exceeding the timeout value would the socket not be closed and
    would you not get a RST back thus identifying by timeout?
