If your self-managed databases are not deployed on Alibaba Cloud, they may accept connections only from specific IP addresses. In this case, you must configure the security settings of your self-managed databases to allow access from Data Transmission Service (DTS) servers. For example, if you deploy a firewall for a database, you must add the CIDR blocks of DTS servers to the IP whitelist of the firewall. For more information about the CIDR blocks of DTS servers in different regions, see Whitelist DTS IP ranges for your user-created database.
Data migration and change tracking
- Data migration
If the source and destination databases of a data migration task are of the self-managed database with a public IP address, self-managed database without a public IP address or port number (connected over Database Gateway), self-managed database connected over Cloud Enterprise Network (CEN), or self-managed database connected over Express Connect, VPN Gateway, or Smart Access Gateway database type, you must modify the database security settings. You must add the CIDR blocks of DTS servers that reside in the same region as the source or destination database to the security settings.
For example, the source database is deployed in the China (Shenzhen) region and the destination database is deployed in the China (Hangzhou) region. In this case, you must add the CIDR blocks of DTS servers in the China (Hangzhou) region to the security settings of the source and destination databases.
- Change tracking
If the database of a change tracking task is of the self-managed database with a public IP address, self-managed database without a public IP address or port number (connected over Database Gateway), or self-managed database connected over Express Connect, VPN Gateway, or Smart Access Gateway database type, you must modify the database security settings. You must add the CIDR blocks of DTS servers that reside in the same region as the database to the security settings.

Data synchronization
- If you want to allow DTS to access the source database, you must modify the security
settings of the source database. You must add the CIDR blocks of DTS servers that
reside in the same regions as the source and destination databases to the security
settings of the source database.
For example, the source database is deployed in the China (Shenzhen) region and the destination database is deployed in the China (Hangzhou) region. In this case, you must add the CIDR blocks of DTS servers in both regions to the security settings of the source database.
- If you want to allow DTS to access the destination database, you must modify the security
settings of the destination database. You must add the CIDR blocks of DTS servers
that reside in the same region as the destination database to the security settings
of the destination database.
For example, the source database is deployed in the China (Shenzhen) region and the destination database is deployed in the China (Hangzhou) region. In this case, you must add the CIDR blocks of DTS servers in the China (Hangzhou) region to the security settings of the destination database.
- Data synchronization does not support databases of the self-managed database with a public IP address database type.
- When an on-premises database is connected to Alibaba Cloud over CEN, Express Connect, VPN Gateway, Smart Access Gateway, or Database Gateway, the CIDR block added to the database security settings is a subnet range of the CIDR block of Alibaba Cloud 100.64.0.0/10.
