Methods

NameAccessible byRequired ParamsDescription
getFirewallSELECTfirewallIdGet a specific Firewall resource by its ID. The Firewall's Devices will not be
returned in the response. Instead, use the
List Firewall Devices
endpoint to review them.
getFirewallsSELECTReturns a paginated list of accessible Firewalls.
createFirewallsINSERTdata__rulesCreates a Firewall to filter network traffic.

Use the rules property to create inbound and outbound access rules.

Use the devices property to assign the Firewall to a service and apply its Rules to the device. Requires read_write User's Grants to the device.
Currently, Firewalls can only be assigned to Linode instances.

A Firewall can be assigned to multiple Linode instances at a time.

A Linode instance can have one active, assigned Firewall at a time.
Additional disabled Firewalls can be assigned to a service, but they cannot be enabled if another active Firewall is already assigned to the same service.

* A firewall_create Event is generated when this endpoint returns successfully.
deleteFirewallDELETEfirewallIdDelete a Firewall resource by its ID. This will remove all of the Firewall's Rules
from any Linode services that the Firewall was assigned to.

A firewall_delete Event is generated when this endpoint returns successfully.
_getFirewallEXECfirewallIdGet a specific Firewall resource by its ID. The Firewall's Devices will not be
returned in the response. Instead, use the
List Firewall Devices
endpoint to review them.
_getFirewallsEXECReturns a paginated list of accessible Firewalls.
updateFirewallEXECfirewallIdUpdates information for a Firewall. Some parts of a Firewall's configuration cannot
be manipulated by this endpoint:

- A Firewall's Devices cannot be set with this endpoint. Instead, use the
Create Firewall Device
and Delete Firewall Device
endpoints to assign and remove this Firewall from Linode services.

- A Firewall's Rules cannot be changed with this endpoint. Instead, use the
Update Firewall Rules
endpoint to update your Rules.

- A Firewall's status can be set to enabled or disabled by this endpoint, but it cannot be
set to deleted. Instead, use the
Delete Firewall
endpoint to delete a Firewall.

If a Firewall's status is changed with this endpoint, a corresponding firewall_enable or
firewall_disable Event will be generated.
