Smart Access Gateway:Configure roaming for clients

Last Updated:Jul 18, 2026

The Smart Access Gateway (SAG) app supports roaming, which allows clients to access private networks across areas for convenient cross-region connectivity to Alibaba Cloud.

Background information

Roaming replicates client account information from an SAG app instance to instances in other areas. After replication, clients can connect to Cloud Connect Network (CCN) instances in those areas and access Alibaba Cloud, enabling cross-region private network access for off-site employees.

Before you use the roaming feature, take note of the following limits:

  • Within the same area, you cannot replicate information about client accounts among SAG app instances.

  • The CIDR blocks of the private networks attached to the source and destination SAG app instances cannot overlap with each other.

  • The client accounts from which information is replicated have not been added to the destination SAG app instance.

Procedure

  1. Log on to the Smart Access Gateway console.

  2. In the navigation pane on the left, choose Smart Access Gateway App > SAG App Instances.

  3. In the top navigation bar, select the region in which you want to create the SAG app instance.

  4. On the SAG App Instances page, click the target instance ID.

  5. On the SAG app instance details page, click the Client Accounts tab and find the target client account.

  6. In the Operation column, choose 更多> Roaming.

  7. On the Configure Roaming page, configure the settings.

    Parameter

    Description

    Client Account

    Select the SAG app instance to which you want to replicate the client account information.
