The simple filters defined can also be seen in the Advanced Filter page as below.

• Address filter
  You can set an address filter by physical address, IP address, IP range and IP subnet. To define an address filter, check the checkbox of Address filter first, select an address type from the upper combo box of Address1, then input an address into the lower combo box or select from the name table. Click the icon to get references if you are not familiar with address formats.
  
  The combo box of Direction is for you to specify the send/receive relationship between the two addresses. You should select Both directions to match all packets going in either direction between address 1 and address 2, otherwise you could instead match only traffic going from address 1 to address 2, or match only traffic going the other direction.
  
  Similar as Address1, you must select an address type and enter a valid address in Address2 , or simply choose Any Address. You can select an address from the name table for both Address1 and Address2 by clicking the icon. Below is an example of address filter.
  
  
   
• Port filter
  To define a port filter, check the Port filter checkbox, select a port type and input parameters with correct format in Port1. Notice that if you select Multiple ports, the ports you enter must be separated with semicolon. Other settings are similar as the Address filter section.
  
  Below is an example of port filter.
  
  
   
• Protocol filter
  To define a protocol filter, check the Protocol filter checkbox, click the Select button to open the Protocol Filter dialog, find protocols by the first alphabet of the protocol name, then select protocols by checking the corresponding check box and click OK to confirm your selection. The selected protocols are listed in the pane at the bottom of the Simple Filter page, you can delete a protocol item from the list with the Remove button.
