Hello @גלעד דואני ,
Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.
I understand that you would like to connect your Azure Labs internal network to your on-premises via ExpressRoute.
I believe you are using Azure lab services. Is that correct?
As per the below doc, for on-premises connectivity using a Virtual Network Gateway, the gateway, specified virtual network, network security group, and the lab plan all must be in the same region.
Refer: https://learn.microsoft.com/en-us/azure/lab-services/how-to-connect-vnet-injection
Below is an Azure lab services blog explaining how to your Azure lab to your on-premises using VPN gateway:
If you see this blog, you can find the below points:
- The lab account resource and the Azure virtual network to be peered must be in the same region.
- The virtual network should be in the same subscription. If this is not possible, as might be the case when using Express Route, the lab account will need to be peered to a Vnet in the same subscription and then a Vnet-to-Vnet connection made with BGP enabled between the peered Vnet and the ExpressRoute hub Vnet.
So, you need to make sure the above pre-requisites are met in order to connect your on-premises to Azure Labs internal network via ExpressRoute.
Kindly let us know if the above helps or you need further assistance on this issue.
