Leave content filtering to the ES, and *force* ES to filter the content.
Its not content filtering, I'm not filtering only certain html traffic 
(like access to porn sites), I'm filtering traffic that is causing harm to 
my network and if I know what traffic is causing problems for me, I'll 
filter it first chance I get.

It is content filtering. You are filtering packets that you think are
causing problems to the ES that you may not control.

No, he said quite clearly he's filtering packets (such as Nachi ICMP) that are
causing harm to *his* network.  He gets to make a choice - filter the known
problem packets so the rest of the traffic can get through, or watch the
network melt down and nobody gets anything.
