Applying Filters
Filters enable you to control network traffic. After you have created filters in the filter
table, you can apply them to the Ethernet interface as either input or output filters. For
more information about filters, see Chapter 9, “Configuring Filters.”
Filters applied to the Ethernet interface take effect immediately. If you change the filter,
the change will not take effect until you set the filter on the interface again or you
reboot the PortMaster.
Input Filters
When an input filter is used, all traffic coming into the PortMaster on the Ethernet
interface is compared to the input filter rules. Only packets permitted by the filter rules
are accepted by the PortMaster.
