Why don't you block by country? Attempts were reduced by 60% by blocking
Taiwan, China and Korea according to someone on another list who was
experiencing a similar inconvenience. Performing some analysis should yield
other countries to block, also. It depends on your business of course, but
if you don't supply products or services to that part of the world why
listen to packets originating there?
