In an internet traffic measurement it is seen that port 14443 carries a large amount of traffic. What exactly is this port? and what can be the explanation?
Possibly BRU backup software (per Internet Storm Center), or misbehaving SonicPoint wireless access points.
Is that port seen from the client side? If so, what server side port is in use? My guess is that's an ephemeral port being used on the client side to connect to a well known port on the server (80, 25, etc).
