Strange UDP Activity

["LAVELLE,MICHAEL (HP-PaloAlto,ex1)" <mlavelle () hp com>]

Greetings to the List,

I recently started seeing strange UDP traffic to my home DSL, which is
included below. It has been active for the last 4 days at all hours. None of
these IPs are DNS servers that I use, and much of the activity is when all
of my computers are off. Google led me to port 1067 as being an SNMP port,
but I have SNMP disabled on all devices at home, and the ACL blocks it
anyway.

Is there a new vulnerability going around that I missed? So far I have not
read anything on the list that looks like this...any ideas?

Thanks for listening,

Mike
