Firewall Create
POST
https://api.linode.com/v4/networking/firewalls
Creates 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_writeUser’s Grants to the device.
Currently, Firewalls can be assigned to Linode compute instances and NodeBalancers.
A Firewall can be assigned to multiple services at a time.
A Firewall can be assigned during Linode creation by utilizing the firewall_idLinode Create Request property.
A service 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.
Firewalls apply to all of a Linode’s non-vlan purpose Configuration Profile Interfaces.
Assigned Linodes must not have any ongoing live migrations.
A firewall_create Event is generated when this endpoint returns successfully.
Devices to create for this Firewall.
When a Device is created, the Firewall is assigned to its associated service.
Currently, Devices can be created for Linode compute instances and NodeBalancers.
Additional devices can be assigned after Firewall creation by using the Firewall Device Create command.
linodes
array
of integers
An array of Linode IDs. A Firewall Device is created for each ID.

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

Currently, Devices with linode and nodebalancer entity types are accepted.
Firewalls only apply to inbound TCP traffic to NodeBalancers.
A Firewall can be assigned to multiple services at a time.
A service 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.
Assigned Linodes must not have any ongoing live migrations.
A firewall_device_add Event is generated when the Firewall Device is added successfully.

assigned to by the Device. This removes all of the Firewall’s Rules from the
service. If any other Firewalls have been assigned to the service, then those Rules
remain in effect.

Must contain ipv4, ipv6, or both.
ipv4
array
of strings
A list of IPv4 addresses or networks. Addresses must be in IP/mask format. Must not be an empty list.
If “0.0.0.0/0” is included in this list, all IPv4 addresses are affected by this rule.
ipv6
array
of strings
A list of IPv6 addresses or networks. Addresses must be in IP/mask format and must not include zone_id notation as described in RFC 4007. Must not be an empty list.
If “::/0” is included in this list, all IPv6 addresses are affected by this rule.

ports
Nullable
string
A string representing the port or ports affected by this rule:
The string may be a single port, a range of ports, or a comma-separated list of single ports and port ranges. A space is permitted following each comma.
A range of ports is inclusive of the start and end values for the range. The end value of the range must be greater than the start value.
Ports must be within 1 and 65535, and may not contain any leading zeroes. For example, port “080” is not allowed.
The ports string can have up to 15 pieces, where a single port is treated as one piece, and a port range is treated as two pieces. For example, the string “22-24, 80, 443” has four pieces.
If no ports are configured, all ports are affected.
