In a non default environment we couldn' use a Gateway to connect to on-premise resources.
It should be posible to reuse/share an existing gateway in non default envrionments to create a connection to an external database (ex. SQL Server on-premise).
We plan to do this feature. Currently, if you have an urgent business need for this feature, we can whitelist your non-default environment to allow gateway. You need to file a support ticket for this and we will evaluate carefully your request.
The Gateway is going to be General available in all environments from October 2019
You can now create and manage gateways in any environment, not just the default environment. This release allows users to use all gateways that they have access to within their environment's region. Admins can use the rich gateway management experience in the Power Platform Admin center to manage and control access to gateways. Admins can also define who can access gateways, and their permissions.
In case you are in urgent for adding this GateWay, you can submit a ticket to PowerApps team from https://admin.dynamics.com or https://admin.powerplatform.microsoft.com/support
With the following information:
The Gateway can be mapped to a non-default environment only if the environment and the gateway are both in the tenant default region.
I'm so happy to hear it.
Thank you for letting us know.
I see it said that the support gateway for all environments will be available in Oct 2019 but this month is Oct. I did not see any update on this.
Does it mean that we still need to raise a ticket? And how long does it take for the ticket?
Do you have any more info on this?
