Filter Builder includes 10 predefined filters, which are displayed on the
Filter screen. Table 30 lists the filters by name, what each does, and
whether the filter operates in the software or the hardware.

You can distinguish predefined filters from the custom filters that you
create by the icon that pertains to each filter's name in the list on the
Filter tab. The icon for predefined filters has a lock in the lower left
corner, which indicates that the filter is write protected; you cannot edit
or delete it.
Although the predefined filters are write-protected, you can edit a
predefined filter indirectly by copying it, giving it a new name, and then
editing it.
To create a filter, Filter Builder has two interfaces:
Filter Wizard — If you are unfamiliar with the packet filtering or to
create a simple filter, use this interface.
Create or Edit Filter window — If you are familiar with the packet
filtering or to create a complex filter, use this interface.
For more information on the Filter Builder tool, see the Web
Management User Guide and the Filter Builder's Help system.
