A filter is a set of judgment conditions that the program uses to match against every captured packet. If match result is positive, the packet is accepted and analyzed. If negative, the program will ignore it. In Capsa, you can manage your filters conveniently and easily create a new one.
This window lists all your filters, to enable one, just check the accept checkbox (no filter enabled by default). And you will see how the filters will work to process the packets in the right panel.
