    If you have rules to authorize and log the services handled by the
    properties, then you might as well (in fact, I'd say you'd be better
    off to) disable them in the properties since the properties will never
    come into play, unless your rules are not all encompassing.  The
    exceptions to this are the handling of established session packets and
    ftp PORT handling (and maybe one or two others that I've forgotten),
    which is difficult, if not impossible, to handle in the ruleset.
