You have All, TCP, UDP, Remote, Listening and Established. If you make one named Process Historic, it shout shove a list of the process that have been active from Port Explorer was started and show the last time the process was active. You can then go to the Log Window, find the time and look at the process. You have also a list of all the process that have been active, a good security information.
