Get started with the SAG app

Procedure

Step 1: Purchase a SAG app instance

Purchase a Smart Access Gateway app instance to centrally manage networks and clients.

1. Log on to the SAG console.
2. In the top navigation bar, select the target region.
3. In the left-side navigation pane, choose Smart Access Gateway App > SAG App Instances.
4. On the SAG App Instances page, click Create SAG App. Set the following parameters, click Buy Now, and complete the payment.

   Parameter	Description
   RegionRegion	The region where the Smart Access Gateway client is used. In this example, China (Shanghai) is selected.
   Number of Client AccountsNumber of Client Accounts	The maximum number of client accounts you can create. After you purchase a specific number of client accounts, you can create the same number of accounts. Typically, one account is created for each employee who needs to log on. This example uses the default value of 10. Note You can select 1~2000 client accounts. Client accounts are billed based on a tiered pricing model. For more information, see Billing rules for SAG app instances.
   Data plan per account	Included data cannot be shared between accounts or carried over to the next month. The default value is 5 GB.
   Billing method for overage	If an account's usage exceeds its data plan, the overage is billed on a pay-as-you-go basis. This example uses Pay-As-You-Go.
   Subscription Period	The subscription duration for the data plan, calculated by month. Auto-renewal is supported. This example uses the default value of 1 Month.
   Resource Group	Select the resource group to which the instance belongs. This example uses Default Resource Group.

Step 2: Configure the network

Configure the network settings for your SAG app instance, including the private CIDR block for clients and the associated Cloud Connect Network (CCN) instance.

CCN is a key component of SAG. Associating your SAG app instance with a CCN instance enables clients to communicate with other gateway devices attached to the same CCN instance. For more information about CCN, see What is Cloud Connect Network?.

1. On the SAG App Instances page, find your new instance and click Quick Configuration in the Operation column.
2. On the Network Configuration page, complete the network configuration as follows:

   Parameter	Description
   Instance Name/ID	The name and ID of the Smart Access Gateway app instance that you created.
   Resource Group	The resource group to which the Smart Access Gateway app instance belongs.
   CCN	Choose one of the following methods to associate a CCN instance. This example uses Create CCN. Existing CCN: If you have an existing CCN instance, select it from the drop-down list. Create CCN: If you do not have a CCN instance, enter a name. The system creates a CCN instance in the current region and automatically associates it with the Smart Access Gateway app instance.
   Standby and Active DNS	This parameter is optional. You can specify the active and standby DNS servers for clients to use when connecting to the private network. After you configure DNS, the settings are automatically pushed to the clients. This example leaves the field blank. Note If clients use PrivateZone to connect to Alibaba Cloud, set the DNS server addresses to 100.100.2.136 and 100.100.2.138. For more information about PrivateZone, see What is PrivateZone?. DNS configuration is supported only on Android clients version 2.1.1 or later and macOS clients version 2.1.1 or later. For more information about clients, see Install the client.
   Private CIDR Block	The private CIDR block used for client connections to Alibaba Cloud. When a client connects, the system automatically assigns an available IP address from this CIDR block. Ensure the CIDR blocks do not overlap. This example uses 192.168.10.0/24. Click Add Private CIDR Block to add more CIDR blocks. You can configure up to five private CIDR blocks.

Step 3: (Optional) Associate with a CEN instance

Associate the CCN instance with a Cloud Enterprise Network (CEN) instance to enable communication between clients and cloud resources attached to the CEN instance. For more information about CEN, see What is Cloud Enterprise Network?.

1. Click Next: Associate with a CEN (optional) to associate a CEN instance.
   This is an optional step. If you do not need to associate a CEN instance, click Skip at the bottom of the page.
2. Use one of the following methods to associate a CEN instance. This example selects an existing CEN instance to enable communication between clients and cloud resources.
   • Instance Name/ID: The name and ID of the CCN instance that you created.
   • Existing CEN: If you have an existing CEN instance, select it from the drop-down list.
   • Create CEN: If you do not have a CEN instance, enter a name. The system creates a CEN instance and automatically associates it with the CCN instance.

Step 4: Create a client account

Create client accounts so that users can log on to the client and connect to the private network.

Step 5: Connect to the cloud

Download and install the client on your device, then use it to connect to the private network and access cloud resources.

1. After the configuration is complete, click Download Now to view download and installation instructions. For more information, see Install the client.
2. After the client is installed, log on to the client with your account credentials and connect to the private network to access cloud resources. For more information, see Connect to a private network.
