Packet Filter is utilized to set the conditions for capturing the traffic on the network.
You can click filter icon to open Packet Filter Settings dialog box which includes a right pane and a left pane.
The left pane lists all available filters including built-in filters and user-defined filters. For each filter, there are two options, Accept and Reject. Accept means only packets matching the filter will be captured by Capsa, while Reject means only packets unmatched will be captured by Capsa. All selected filters are in OR relationship.
The right pane is filter flow chart which shows all selected filter items on the filter list, including Accept ones and Reject ones. It refreshes upon any changes on the filters. You can double-click a filter on the flow chart to edit it.
There are six buttons for setting packet filters.
