No insight into your question, but I'd like to tag on my own... I'm
puzzled by mystery Microsoft UDP traffic from:

  65.54.240.61 port 7001 to <machine on local subnet> port 1052
  65.54.240.62 port 7001 to <machine on local subnet> port 1070

I also see traffic from these ip/port combinations to high port
addresses. I suspect this traffic is related to MSN Messenger. My
firewall drops the traffic, and I see no ill effects.
