Anyone else seeing webtv probing your customers for QAZ?
The following webtv hosts seem to be probing our dialup customers port
WebTV Networks is not probing for QAZ.
After reviewing the log files Dan Hollis provided, it appears that
these packets are normal TCP communication between a WebTV terminal
and the WebTV service. The client terminal initiates a connection,
picking a random source port. The service is trying to establish a
connection with the client using that port. This behavior is not
limited to WebTV. It appears that the packet from the service was
caught in Dan's perimeter router ACL.
Please do not hesitate to contact us if you have any concerns about
WebTV and security or network interoperability issues. Please see
