Just so people are aware at this rather strange change.  We have an
explicit reject at the bottom of our iptables scripts.  We're seeing some
LAST_ACK's getting denied by the proxy servers iptables rules, generating
this traffic.

The network team requested we get rid of these ICMP messages so I have the
iptables rules explicitly drop the messages before they get to the reject
rule.  This is a temporary change.
