Detailed Description

A class for filtering TCP or UDP port ranges, meaning match only packets which port is within this range, for example: "src portrange 1000-2000" will match only TCP or UDP traffic which source port is in the range of 1000 - 2000
For deeper understanding of the filter concept please refer to PcapFilter.h
