What is a virtual network (VNet) data gateway (Preview)?

The virtual network (VNet) data gateway helps you to connect from Microsoft Cloud services to your Azure data services within a VNet without the need of an on-premises data gateway. The VNet data gateway securely communicates with the data source, executes queries, and transmits results back to the service.

Limitations

• Currently, this feature is available only for Power BI datasets, Power Platform dataflows, and Power BI paginated reports. Power BI dataflows and datamarts are not supported.

• This feature is currently not supported in sovereign clouds.

• Due to an Azure AD limitation you might encounter failures when the following settings are enabled together:

  • Service endpoint for Azure AD is enabled on the delegated VNet.
  • Conditional access policies are enabled for the tenant.

  To overcome this Azure AD limitation, you can try the following workaround:

  • If you have VNet traffic blocked by a conditional access policy, check your Azure AD sign-in log. Once you've identified the traffic, you can get the IPv6 address being used and exclude it from your policy. More information: Location condition in Azure Active Directory conditional access

• You can't change the region, subscription, or resource group for the VNet on which the VNet data gateway was created. This scenario isn't currently supported.

• Power BI datasets:

  • A list of supported data services for Power BI datasets is available in Supported Azure data services.

• Power Platform dataflows:

  • For Power Platform dataflows, this feature currently doesn't support the ability to write to a privatized data lake or Dataverse.
  • A list of supported data sources for Power Platform dataflows is available in Supported data sources.
  • The physical VNet data gateway is injected into your virtual network and subnet, so it operates in the same region as the virtual network.
  • The VNet data gateway can be accessed through the application only from the home region of your tenant. There's currently no option to change the VNet data gateway region.
  • VNet data gateways currently support only admin roles and not "Can Use and Can Use+Share" for Power Platform dataflows.

• Power BI paginated reports:

  • VNet gateways support paginated reports.
  • A list of supported data sources for Power BI paginated reports is available in Supported data sources for Power BI paginated reports.
