PolicyNatRule

Represents a NAT rule between source and destination at T0/T1 router.


Properties

Required Property Name Type Description
optional _create_time integer

Timestamp of resource creation

optional _create_user string

ID of the user who created this resource

optional _last_modified_time integer

Timestamp of last modification

optional _last_modified_user string

ID of the user who last modified this resource

optional _links array of ResourceLink

The server will populate this field when returing the resource. Ignored on PUT and POST.

optional _protection string

Protection status is one of the following: PROTECTED - the client who retrieved the entity is not allowed to modify it. NOT_PROTECTED - the client who retrieved the entity is allowed to modify it REQUIRE_OVERRIDE - the client who retrieved the entity is a super user and can modify it, but only when providing the request header X-Allow-Overwrite=true. UNKNOWN - the _protection field could not be determined for this entity.

optional _revision integer

The _revision property describes the current revision of the resource. To prevent clients from overwriting each other’s changes, PUT operations must include the current _revision of the resource, which clients should obtain by issuing a GET operation. If the _revision provided in a PUT request is missing or stale, the operation will be rejected.

optional _schema string

Schema for this resource

optional _self SelfResourceLink

Link to this resource

optional _system_owned boolean

Indicates system owned resource

optional action string

Source NAT(SNAT) - translates a source IP address in an outbound packet so that the packet appears to originate from a different network. SNAT is only supported when the logical router is running in active-standby mode. Destination NAT(DNAT) - translates the destination IP address of inbound packets so that packets are delivered to a target address into another network. DNAT is only supported when the logical router is running in active-standby mode. Reflexive NAT(REFLEXIVE) - IP-Range and CIDR are supported to define the “n”. The number of original networks should be exactly the same as that of translated networks. The address translation is deterministic. Reflexive is supported on both Active/Standby and Active/Active LR. NO_SNAT and NO_DNAT - These do not have support for translated_fields, only source_network and destination_network fields are supported.

optional children array of ChildPolicyConfigResource

subtree for this type within policy tree containing nested elements.

optional description string

Description of this resource

optional destination_network string

IP Address | Comma separeted list of IP addresses | CIDR. For DNAT and NO_DNAT rules, this is a mandatory field, and represents the destination network for the incoming packets. For other type of rules, optionally it can contain destination network of outgoing packets. NULL value for this field represents ANY network.

optional display_name string

Defaults to ID if not set

optional enabled boolean

The flag, which suggests whether the NAT rule is enabled or disabled. The default is True.

optional firewall_match string

It indicates how the firewall matches the address after NATing if firewall stage is not skipped.

MATCH_EXTERNAL_ADDRESS indicates the firewall will be applied to external address of a NAT rule. For SNAT, the external address is the translated source address after NAT is done. For DNAT, the external address is the original destination address before NAT is done. For REFLEXIVE, to egress traffic, the firewall will be applied to the translated source address after NAT is done; To ingress traffic, the firewall will be applied to the original destination address before NAT is done.

MATCH_INTERNAL_ADDRESS indicates the firewall will be applied to internal address of a NAT rule. For SNAT, the internal address is the original source address before NAT is done. For DNAT, the internal address is the translated destination address after NAT is done. For REFLEXIVE, to egress traffic, the firewall will be applied to the original source address before NAT is done; To ingress traffic, the firewall will be applied to the translated destination address after NAT is done.

BYPASS indicates the firewall stage will be skipped.

For NO_SNAT or NO_DNAT, it must be BYPASS or leave it unassigned

optional id string

Unique identifier of this resource

optional logging boolean

The flag, which suggests whether the logging of NAT rule is enabled or disabled. The default is False.

optional marked_for_delete boolean

Intent objects are not directly deleted from the system when a delete is invoked on them. They are marked for deletion and only when all the realized entities for that intent object gets deleted, the intent object is deleted. Objects that are marked for deletion are not returned in GET call. One can use the search API to get these objects.

optional parent_path string

Path of its parent

optional path string

Absolute path of this object

optional relative_path string

Path relative from its parent

optional resource_type string

The type of this resource.

optional scope array of string

Represents the array of policy paths of ProviderInterface or NetworkInterface or labels of type ProviderInterface or NetworkInterface on which the NAT rule should get enforced. The interfaces must belong to the same router for which the NAT Rule is created.

optional sequence_number integer

The sequence_number decides the rule_priority of a NAT rule. Sequence_number and rule_priority have 1:1 mapping.For each NAT section, there will be reserved rule_priority numbers.The valid range of rule_priority number is from 0 to 2147483647(MAX_INT). 1. INTERNAL section rule_priority reserved from 0 - 1023 (1024 rules) valid sequence_number range 0 - 1023 2. USER section rule_priority reserved from 1024 - 2147482623 (2147481600 rules) valid sequence_number range 0 - 2147481599 3. DEFAULT section rule_priority reserved from 2147482624 - 2147483647 (1024 rules) valid sequence_number range 0 - 1023

optional service string

It represents the path of Service on which the NAT rule will be applied. If not provided or if it is blank then Policy manager will consider it as ANY.

optional source_network string

IP Address | Comma separeted list of IP addresses | CIDR. For SNAT, NO_SNAT and REFLEXIVE rules, this is a mandatory field and represents the source network of the packets leaving the network. For DNAT and NO_DNAT rules, optionally it can contain source network of incoming packets. NULL value for this field represents ANY network.

optional tags array of Tag

Opaque identifiers meaningful to the API user

optional translated_network string

IP Address | Comma separeted list of IP addresses | CIDR. For SNAT, DNAT and REFLEXIVE rules, this ia a mandatory field, which represents the translated network address. For NO_SNAT and NO_DNAT this should be empty.

optional translated_ports string

Port number or port range
