如果您的自建数据库不是部署在阿里云上，它们可能只接受与特定IP地址建立连接。 在这种情况下，您需要将DTS服务器的IP地址段加入到自建数据库对应的安全设置（通常为您自建数据库的防火墙）中，以允许来自DTS服务器的访问。
说明 如果源或目标数据库是阿里云数据库实例（例如RDS、MongoDB等）或ECS上的自建数据库，DTS会自动将对应地区DTS服务的IP地址添加到阿里云数据库实例的白名单或ECS的安全规则中，您无需手动添加。

数据迁移/订阅
- 数据迁移
当数据迁移的源或目标数据库为有公网IP的自建数据库、无公网IP:Port的数据库（通过数据库网关DG接入）、通过云企业网CEN接入的自建数据库或通过专线/VPN网关/智能网关接入的自建数据库时，通过下表定位到目标数据库所在区域，获取对应区域DTS服务的IP地址段，并将其加入到源和目标数据库的安全设置中。
例如：源数据库地区为深圳，目标数据库地区为杭州，您只需要将杭州地区DTS服务的IP地址段加入到源和目标数据库的安全设置中。
- 数据订阅
当数据订阅的源数据库为有公网IP的自建数据库、无公网IP:Port的数据库（通过数据库网关DG接入）或通过专线/VPN网关/智能网关接入的自建数据库时，通过下表定位到源数据库所在区域，获取对应的DTS服务的IP地址段并将其加入到源数据库的安全设置中。
说明 如果您的源或目标数据库为
有公网IP的自建数据库，且DTS提供的区域未覆盖您自建数据库所在区域，则可以选择填入任意区域DTS服务的IP地址，推荐选择华东1（杭州）DTS服务的IP地址。

数据同步
当数据同步的源和目标数据库为
无公网IP:Port的数据库（通过数据库网关DG接入）或
通过专线/VPN网关/智能网关接入的自建数据库时，您需要根据业务情况进行配置：
- 如果需要放开DTS对源数据库的访问限制，您需要通过下表定位到源和目标数据库所在区域，获取对应区域DTS服务的IP地址段，并将其加入到源数据库的安全设置中。
例如：源数据库地区为深圳，目标数据库地区为杭州，您需要将深圳和杭州地区DTS服务的IP地址段，都加入到源数据库的安全设置中。
- 如果需要放开DTS对目标数据库的访问限制，通过下表定位到目标数据库所在区域，获取对应区域DTS服务的IP地址段，并将其加入到目标数据库的安全设置中。
例如：源数据库地区为深圳，目标数据库地区为杭州，您只需将杭州地区DTS服务的IP地址段，加入到目标数据库的安全设置中。
说明 数据同步暂不支持接入
