Minimum: 0

Maximum: 1

Default: 0

floating_ip_id

String

Specifies the EIP ID. Use commas (,) to separate multiple EIP IDs.

description

String

Provides supplementary information about the SNAT rule. The description can contain up to 255 characters and cannot contain angle brackets (<>).

Minimum: 0

Maximum: 255

status

String

Specifies the SNAT rule status. The value can be: ACTIVE: The SNAT rule is available. PENDING_CREATE: The SNAT rule is being created. PENDING_UPDATE: The SNAT rule is being updated. PENDING_DELETE: The SNAT rule is being deleted. EIP_FREEZED: The EIP is frozen. INACTIVE: The SNAT rule is unavailable.

Enumeration values:

  • ACTIVE

  • PENDING_CREATE

  • PENDING_UPDATE

Maximum: 36

network_id

String

Specifies the network ID used by the SNAT rule. Configure either network_id or cidr.

Minimum: 36

Maximum: 36

admin_state_up

Boolean

Specifies whether the SNAT rule is frozen. The value can be:

  • true: The SNAT rule is unfrozen.

  • false: The SNAT rule is frozen.

floating_ip_address

String

Specifies the EIP. Use commas (,) to separate multiple EIPs.

freezed_ip_address

String

Specifies the frozen EIP. Use commas (,) to separate frozen EIPs.

global_eip_id

String

Specifies the global EIP ID.

global_eip_address

String

Specifies the global EIP address.
