Changing the Receive Port

You can change the Receive port of an address entry in the scrollable panel, so that a frame must be received at the speciÞed port for the Þltering action to apply. To do so, click on the Receive port in the panel. With each click, the Receive port will cycle to the next port (e.g., from * (promiscuous), to 1, to 2, to 3, to 4, to 5, up to 32, back to *).
