Working with IP Filters and Filter Sets
To work with filters and filter sets, begin by accessing the filter set pages.

The procedure for creating and maintaining filter sets is as follows:
1. Add a new filter set.

2. Create the filters for the new filter set.
See “Adding filters to a filter set” on page 172.
3. Associate the filter set with either the LAN or WAN interface.
See “Associating a Filter Set with an Interface” on page 176.
The sections below explain how to execute these steps.
Adding a filter set
You can create up to eight different custom filter sets. Each filter set can contain up to 16 output filters and

Enter new name for the filter set, for example Filter Set 1.
To save the filter set, click the Submit button. The saved filter set is empty (contains no filters), but you
