What to do to connect to on-prem file share which are in the same virtual network as the logic app

Question

Hi, I would like draw up the step by step procedure to be able to connect to on-prem file share which are in the same virtual network as the logic app from Postman (without using on-prem data gateway).

Correct me if I wrote anything wrong and answer Q) plz.

1. Create a virtual network Subnet - Q) does the Subnet only affect the inbound traffic or also outbound traffic (for example, from logic app to On-prem network folder)?
2. Connect your on-premise computers and networks to the virtual network Site-to-site VPN 2-1) Deploy VPN gateway in Azure : I get an error that‘Not allowed resource type: Public IPs’ due to thesecurity guideline enforcement. Is Public IP required? 2-2) Create a local network gateway 2-3) Establish connection between VPN gateway and local network gateway 2-4) RRAS - create a network interface
3. Create an App Service environment (ASE) Virtual IP type - 'External' because the http request will be called from Postman (external system) Subnet - subnet of the VNET. Q) what should be the subnet address range?
4. Create a standard logic app Select the ASE created in step 3 as a Region when creating the Logic App Trigger - 'when a HTTP request is received' Action - Create a built-in filesystem action (!not a Azure file system connector)

Answer 1

@Shawn Thanks for reaching out. You can leverage the standard logic app with Build in file system connector/file system for your requirement. To setup the virtual network integration on your standard logic app you can refer to this document.

does the Subnet only affect the inbound traffic or also outbound traffic

Can you please clarify more do you mean inbound and outbound rule or the NSG here?

For your 2nd query I will suggest either to create a new thread with the Azure network tag so it would be easier for others facing the similar issue. I will check internally with the network team if they can share any insights on this.

what should be the subnet address range?

Ideally you should select the max address space that your resource would be scaled up.

Create a standard logic app Select the ASE created in step 3 as a Region when creating the Logic App Trigger - 'when a HTTP request is received' Action - Create a built-in filesystem action (!not a Azure file system connector)

Yes, you need to use the build in action as inbuild connectors can access your resources on the same network.
