This dialog allows you to configure the filters used for displaying the information in the NetStat window. By default, NetStat lists all of your computer's network connections. This list is usually rather long, and you may want to filter out some of the items that are unimportant to you.


To create a new filter, enter the Value, select the filter type (Local IP, Local Port, etc.), and click Add Record. To remove a filter, select it from the list and click Clear Selected. Once you have created one or several new filters, you should select the Action. If you select Show, NetStat will display only the connections that match the filter(s). If you select Ignore, NetStat will not display any connection that matches the filter(s). If you have created multiple filters, you should also choose Boolean logic to be used: it can be either And (Filter 1 and Filter 2 and Filter 3, etc.) or Or (Filter 1 or Filter 2 or Filter 3, etc.). The screen shot above illustrates a rule set that makes NetStat hide the connections where the remote port is 80, or local port is 139, or process name is svchost.exe.

Additionally, you can use the following basic filters:

· Don't show UDP statistics – check this box if you don't want to have UDP connections listed in the NetStat window.
· Don't show TCP statistics - check this box if you don't want to have TCP connections listed in the NetStat window.
· Show established only - check this box if you want the NetStat window to list established connections only. All other connections (listening, closing, etc.) will not be listed.

You can temporarily disable filters by selecting the Disable Filters command in the NetStat context menu.
