Establish connectivity between edge device and IoTHub Private Link endpoint over Azure P2S infrastructure

KumarKalambettuGanesh-7003 1

I have done the following steps:

Have provisioned Azure P2S VNET infrastructure.
Have provisioned IoTHub and created a private link endpoint on the virtual network.

Requirement:
Want to ingest data from edge device connected to VPN gateway using VPN client. Can someone provide mechanisms how this can be achieved?

I have tried creating a linux edge gateway on the same VNET where the private endpoint is provisioned, use the raspberry online simulator tool with the SAS connectionstring for iothubowner, but it does not work.

Even if I want to deploy standard simulator modules to edge and establish connectivity, what is the SAS connection string (is it one with public endpoint) that I use with the config.yaml for the edge runtime configuration.

Any reference to end-end demo setup guide should be useful.

Thanks

Hello @KumarKalambettuGanesh-7003

Your steps looks promising to me as it looks like you have invested a good amount of time in the whole setup. I would try to verify my steps once again, especially the outgoing traffic from the VM which is inside the VPN.

You might have already watched this channel9 video, but wanted to highlight the same once again.

Thank you Satish for the response.
I have gone through the video link already. However, it seem to not work for me the same way. Particularly, the step where a VM is created within the VNET and the raspberry PI simulator from VM's browser being able to connect over private endpoint automatically.

The nslookup from my edge VM does not resolve directly to the private endpoint as it does on the Channel9 video. It list both the public and private endpoints. Hence I suppose the connectivity defaults to public endpoint and does not succeed because I have blocked access to IotHub's pubic endpoint.

Hello @KumarKalambettuGanesh-7003 No worries, We will work together on this to resolve.

Let me also take a look at my setup today and will get back to you soon.

This is taking a little bit longer than we expected. sorry for the delay.
