30.1 Default Behavior

Specify the default behavior for ports and protocols. The default behavior is applied to all ports and protocols unless it is overridden by a port/protocol rule or an Access Control List.

Select one of the following behaviors:

  • Stateful: Blocks all unsolicited inbound network traffic. Allows all solicited inbound network traffic and all outbound network traffic.

  • Open: Allows all inbound and outbound network traffic. Because all network traffic is allowed, a device’s identity is visible on all ports.

  • Closed: Blocks all inbound and outbound network traffic. Because all network identification requests are blocked, a device’s identity is concealed on all ports.

    If you select this option, you should enable the ZENworks Server ACL and ARP ACL (see Section 30.4, Standard Access Control Lists) to ensure that the device can communicate with ZENworks Servers to receive content (policies, bundles, and so forth) and upload report data.

  • Inherit: If the policy’s Inherit from Policy Hierarchy setting is enabled, inherits this setting value from other Firewall policies assigned higher in the policy hierarchy. For example, if you assign this policy to a user, the setting value is inherited from any Firewall policies assigned to the user’s groups, folders, or zone.
