Edge NAT Services
NSX Edge provides network address translation (NAT) service to assign a public address to a computer or group of computers in a private network. Using this technology limits the number of public IP addresses that an organization requires. You must configure NAT rules to provide access to services running on privately addressed virtual machines.
- API-URL is a URL of the form https://vcloud.example.com/network.
- id is a VMware Cloud Director unique identifier in the form of a UUID, as defined by RFC 4122.
- # is a small integer used in an NSX object identifier.

| Append a NAT rule to NAT rules on the edge with identifier id. | POST API-URL/edges/id/nat/config/rules | natRules | 201 Created |
| Add an edge NAT rule above the rule with identifier# on the edge with identifier id. | POST API-URL/edges/id/nat/config/rules/?aboveRuleId=# | natRule | 201 Created |
| Update edge NAT rule with identifier# on the edge with identifier id. | PUT API-URL/edges/id/nat/config/rules/# | natRule | 204 No Content |
| Delete edge NAT rule with the identifier# from the edge with identifier id. | Delete API-URL/edges/id/nat/config/rules/# | None | 204 No Content |
Note:
Every external IP address associated with a NAT rule must be registered as a secondary address on the Edge Gateway's uplink interface. The VMware Cloud Director API for NSX handles this registration automatically. Administrators using the NSX API must register those external IP addresses manually.
