<more of same snipped>

UDP port 39213 is used by the Sygate Home Network Manager - a web
search (via google) will pop up other reports of this.  (sometimes,
the source UDP address is in the private 192.168.* address space)  In
all likelihood, this means that some poor adelphia.net user has bought
a Sygate Home Network firewall product and failed to configure it
correctly before connecting it to their cable modem.

As the only bugtraq article I can find about Sygate seems to indicate
a hole via TCP port 7323 connections, it is unlikely that this was
looking to exploit anything.
