    According to Check Point sources this is undocumented. Having also read
    through the CCSE manuals the only thing close to a caveat I can find is the
    following
    (CCSA manual- Page 5-49 - Configuring Control Properties)
    
    Begin Quote
    
    Currently, the most common errors during implementation of Firewall-1 are
    made in the Control Properties. The reason for these errors are:
    
    1) Misunderstanding the importance of direction when packets are inspected,
    and
    2) Misunderstanding of how the Control Properties and the Rule Base
    Matching Order work together.

    So the closest thing to a warning, comes not in the manuals that come with
    the software - but you have to pay to go on a course for this info. I may
    be wrong about this - if you know of any other place where this is
    documented please let me know.
