Configuring Content Filtering Maps for Zone-based Firewall Policies
Configuring URL Filter Parameter Maps
Use the Add and Edit URL Filter Parameter Map dialog boxes to define the parameters and match
criterion and values for an inspection map used in a zone-based firewall policy for a router.
If you configure the action of a zone-based firewall policy rule as Content Filter, you can select a URL
Filter parameter map to define web filtering parameters and match criteria. However, if the router is
running Cisco IOS Software release 12.4(20)T or higher, the recommended approach is to configure a
Web Filter policy map along with parameter and class maps for the appropriate server type (local, N2H2,
Trend, or Websense). For more information, see Configuring Web Filter Maps, page 21-46.
Navigation Path
Select Manage > Policy Objects, then select Maps > Parameter Maps > Web Filter > URL Filter in
the table of contents. Right-click inside the work area and select New Object, or right-click a row and
select Edit Object.
