The edge gateway for Advanced Networking Services provides a network address translation (NAT) service to assign a public address to a virtual machine or group of virtual machines in a private network.

For more information about the NAT features for Advanced Networking Services, see Network Address Translation (NAT) in the vCloud Air Advanced Networking Services Guide.

Prerequisites
1

Log in to vCloud Air as an administrator. See Log in to vCloud Air for information.

2

Create a login session with vCloud Director. See Create a Session for a Virtual Data Center in a Service for information.

3

Using the vCloud API, query vCloud Director for the ID of the edge gateway you require NAT configuration details about. See Querying the vCloud API for information.

Procedure
♦

To get the details for the NAT configuration, issue the following request:

GET https://vchs.vmware.com/hybridity/api/gateways/gatewayId/nat/config

In the request header, include the OATH token and the Accept header that you obtained when creating a login session: 

Accept: application/json
Content-Type: application/json
X-Vcloud-Authorization: "vcloud-auth-token"

If the request is successful, the server returns HTTP response code 200 and the details of the NAT configuration.
