April Port Scans

Analysis of the logs files from my ADSL router for April, there was a large peak of UDP scans which was traced to Akamai who where attempted to connect to the peer to peer network component of their download engine that Adobe use. This peer to peer connection is used by Akamai to allow copies of the download products to be retrieved from the 'client' machines spreading the load from their servers to those who download the producta. The download engine sends messages to the Akamai servers as to which UDP ports it is listening on, however although it may open the ports in the host firewall, the connections where rejected by the firewall in my ADSL router.
