Traffic Filters

The SoftPerfect Network Protocol Analyzer uses filters to include or exclude network packets. Most of the filters can be either inclusive or exclusive. In other words, they either accept or reject packets based on the criteria you have selected. If a filter is enabled, any packets that do not match the conditions set in that filter are discarded. This enables you to focus your analysis only on those packets of interest to you. To apply a filter, choose Filters - Filter Settings from the main menu. When you have created a filter using the above settings you can save it for further use by selecting Filters - Save Filter from the main menu.

Hardware Filter

This tool filters packets based on a selected hardware mode.

• Promiscuous - Receives all packets passing through the the network interface card.
  
• Owner All - Receives only packets intended for, or sent from, a specified network interface card. Many wireless network cards require this option instead of promiscuous mode.
  
• Owner Received - Receives only those packets intended for the selected network interface card.
  
• Broadcast - Accepts only broadcast packets.

Protocol Filter

You can use the protocol filter to include or exclude packets based on protocol.

MAC and IP Address Filters

Enter the addresses between which you want to filter the traffic. All traffic destined for addresses outside the specified addresses will be either excluded or included.

Port Filter

You can select one or more ports by entering numeric values or selecting from a predefined list of port labels. Those packets that have a port address in your list will be included or excluded.
