Associating Subnets with a Firewall

Scenarios

On the page showing firewall details, associate desired subnets with a firewall. After a firewall is associated with a subnet, the firewall denies all traffic to and from the subnet until you add rules to allow traffic.

Procedure

1. Log in to the management console.

2. Click in the upper left corner and select the desired region and project.
3. On the console homepage, under Network, click Virtual Private Cloud.
4. In the navigation pane on the left, choose Access Control > firewalls.
5. Locate the target firewall and click its name to switch to the page showing details of that particular firewall.
6. On the displayed page, click the Associated Subnets tab.
7. On the Associated Subnets page, click Associate.
8. On the displayed page, select the subnets to be associated with the firewall, and click OK.

Subnets that have already been associated with firewalls will not be displayed on the page for you to select. One-click subnet association and disassociation are not currently supported. Furthermore, a subnet can only be associated with one firewall. If you want to reassociate a subnet that has already been associated with another firewall, you must first disassociate the subnet from the original firewall.
