Creating a Zone and Adding Interfaces to the Zone

Creating a Zone and Adding Interfaces to the Zone

Context

To configure firewall functions, create zones. Then you can deploy security services according to the priorities of the zones. The device considers that data transmission within a zone is reliable and does not enforce any security policy on intra-zone data transmission. The device verifies data and enforces security policies only when the data is transmitted from one zone to another.

You must configure a priority for a zone before making other configurations. The priority cannot be changed. Each zone must have a different priority. A larger priority value indicates a higher priority.

The firewall takes effect only after interfaces are added to zones.

The device automatically creates a zone named Local. The Local zone has the highest priority and cannot be deleted. In addition, the priority of this zone cannot be changed, and no interface can be added to this zone. To apply the firewall function to the control packets that need to be processed by the device, use the Local zone.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    firewall zone zone-name

    A zone is created.

    By default, no zone is created on the Router.

  3. Run:

    priority security-priority

    A priority is set for the zone.

  4. Run:

    quit

    Return to the system view.

  5. Run:

    interface interface-type interface-number

    The interface view is displayed.

  6. Run:

    zone zone-name

    The interface is added to the zone.

    Each zone has multiple interfaces, but an interface can be added to only one zone.
