   Figure 6.25. Creating a new DenyService

2. Enter a name for the service into the opening dialog. Use clear, informative, and consistent service names. It is recommended to include the following information in the service name:

   • source zones, indicating which clients may use the service (for example, intranet)

   • the protocol permitted in the traffic (for example, HTTP)

   • destination zones, indicating which servers may be accessed using the service (for example, Internet)

   Tip
   Name the service that allows internal users to browse the Web intra_HTTP_internet. Use dots to indicate child zones, for example, intra.marketing_HTTP_inter.

3. Click in the Class field and select DenyService.

4. To specify how Application-level Gateway rejects the traffic matching a DenyService, use the Deny IPv4 with and Deny IPv6 with options. By default, Application-level Gateway simply drops the traffic without notifying the client.

5. Commit your changes.
