Example 1: Creating an S2C VPN Gateway

Scenario

This section describes how to create an S2C VPN gateway by calling an API.

Prerequisites

• You have created a VPC. For details, see Creating a VPC.
• You have determined the region where the VPN gateway is to be deployed and obtained the endpoint for calling APIs based on the region.
• You have obtained a user token if you need to use token authentication. In addition, you need to add X-Auth-Token to the request header when calling an API. For details about token authentication, see Authentication.

The token obtained through IAM is valid for only 24 hours. When using a token for authentication, cache it to avoid frequent calling.

Data Preparation

Procedure

1. Create a VPN gateway associated with a VPC.
   1. Send POST https://{endpoint}/v5/{project_id}/vpn-gateways.
   2. Add X-Auth-Token to the request header.
   3. Specify the following parameters in the request body:

      1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

      { "vpn_gateway": { "vpc_id": "cb4a631d-demo-a8df-va86-ca3fa348c36c", "local_subnets": [ "192.168.0.0/24", "192.168.1.0/24" ], "connect_subnet": "f5741286-demo-a8df-va86-2c82bd9ee114", "eip1": { "id": "cff40e5e-demo-a8df-va86-7366077bf097" }, "eip2": { "id": "d290f1ee-demo-a8df-va86-d701748f0851" } } }

   4. Check the response.
      • The request is successful if the following response is displayed. In the response, id indicates a VPN gateway ID.

        {
            "vpn_gateway": {
                "id": "620d99b8-demo-a8df-va86-200b868f2d7d",

            "request_id": "4a739f5c-edb7-4122-b31f-b77fb1b94857"
        }

2. Query details about the VPN gateway.
   1. Send GET https://{endpoint}/v5/{project_id}/vpn-gateways/{vgw_id}.
   2. Add X-Auth-Token to the request header.
   3. Check the response.
      • The request is successful if the following response is displayed. In the response, id indicates a VPN gateway ID.
