I'm still working on details here but has anyone seen a sequence like this
which I have captured from the inside interface our firewall; the first
packet is allowed through the firewall inbound, the second with a foreign
source address and a disallowed destination address will be stopped outbound
when it reaches the firewall; is "localhostaddress.edu" infected with
something known?
