Create or update NAT Rule

Create or update NAT Rule on Tier-0 denoted by Tier-0 ID, under NAT section
denoted by <nat-id>.
Under tier-0 there will be 3 different NATs(sections).
(INTERNAL, USER and DEFAULT)
For more details related to NAT section please refer to PolicyNAT schema.
Note:
IPSecVpnSession as Scope: Please note that old IPSecVpnSession policy path deprecated. If user specifiy old IPSecVpnSession path in the
scope property in the PUT API, the path returned in the PUT/GET response payload will be a new path instead of the deprecated IPSecVpnSession path
Both old and new IPSecVpnSession path refer to same resource. there is no functional impact.
This API is available when using VMware Cloud (AWS, Dell-EMC, Outpost, Hyperscalers) or VMware NSX.

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.	string	Readonly
_revision	Generation of this resource config 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.	int

_self	Link to this resource	SelfResourceLink	Readonly
_system_owned	Indicates system owned resource	boolean	Readonly
action	Represents action of NAT Rule SNAT, DNAT, REFLEXIVE 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.

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	string	Enum: MATCH_EXTERNAL_ADDRESS, MATCH_INTERNAL_ADDRESS, BYPASS Default: "MATCH_INTERNAL_ADDRESS"

marked_for_delete	Indicates whether the intent object is marked for deletion 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.	boolean	Readonly Default: "False"

It indicates that Nat policy will be applied to the inbound traffic on Routed Based VPN tunnel, if the policy based VTI is in the "scope" for this rule. Default value will be set to BYPASS if MATCH - It indicates that this NAT rule will only match the Policy Based VPN traffic.	string	Enum: BYPASS, MATCH
realization_id	A unique identifier assigned by the system for realizing intent This is a UUID generated by the system for realizing the entity object. In most cases this should be same as 'unique_id' of the entity.

Realization id is helpful for users to debug data path to correlate the configuration with corresponding intent.	string	Readonly
relative_path	Relative path of this object Path relative from its parent	string	Readonly

service	Represents the service on which the NAT rule will be applied 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. Please note, if this is a DNAT, the destination_port of the service will be realized on NSX Manager as the translated_port. And if this is a SNAT, the destination_port will be ignored.	string
source_network	Represents the source network address This supports single IP address or comma separated list of single IP addresses or CIDR. This does not support IP range or IP sets. For SNAT, NO_SNAT, NAT64 and REFLEXIVE rules, this is a mandatory field and represents the source network of the packets leaving the network.

Comma separated list of single IP addresses is not suported for DNAT and REFLEXIVE rules. For SNAT, DNAT, NAT64 and REFLEXIVE rules, this ia a mandatory field, which represents the translated network address. For NO_SNAT and NO_DNAT this should be empty. For VPC SNAT and Refelexive NATRule, translated network address should be IPv4 address allocated from External Block associated with VPC.	IPElementList
