This topic provides the CIDR blocks of DTS servers that reside in different regions. To ensure that DTS can access the source and destination databases, you must add the CIDR blocks of DTS servers to the security settings (for example, IP whitelist) of the databases. This is required if the database type is User-Created Database with Public IP Address, Database without public IP:Port (Accessed through database gateway), Self built database accessed through Cloud Enterprise Network(CEN), or User-Created Database Connected Over Express Connect, VPN Gateway, or Smart Access Gateway.
Data migration and change tracking
- Data migration
You must modify the security settings of the source and destination databases if the database type is User-Created Database with Public IP Address, Database without public IP:Port (Accessed through database gateway), Self built database accessed through Cloud Enterprise Network(CEN), or User-Created Database Connected Over Express Connect, VPN Gateway, or Smart Access Gateway. You must add the CIDR blocks of DTS servers that reside in the same region as the 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
You must modify the security settings of the source database if the database type is User-Created Database with Public IP Address, Database without public IP:Port (Accessed through database gateway), or User-Created Database Connected Over Express Connect, VPN Gateway, or Smart Access Gateway. You must add the CIDR blocks of DTS servers that reside in the same region as the source 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.
