Enabling or Disabling a Firewall

Scenarios

After a firewall is created, you may need to enable it based on network security requirements. You can also disable an enabled firewall if needed. Before enabling a firewall, ensure that subnets have been associated with the firewall and that inbound and outbound rules have been added to the firewall.

When a firewall is disabled, custom rules will become invalid while default rules still take effect. Disabling a firewall may interrupt network traffic. For information about the default firewall rules, see Default Firewall Rules.

Procedure

  1. Log in to the management console.
  1. Click in the upper left corner and select the desired region and project.
  2. Click in the upper left corner and choose Network > Virtual Private Cloud.

    The Virtual Private Cloud page is displayed.

  3. In the navigation pane on the left, choose Access Control > Firewalls.
  4. Locate the row that contains the firewall, click More in the Operation column, and click Enable or Disable.
  5. Click Yes in the displayed dialog box.
