Static IP of Logic App Standard using NAT Gateway

This post has been republished via RSS; it originally appeared at: Microsoft Tech Community - Latest Blogs - .



Route Logic App Standard traffic through your Virtual Network through specified static public IP address(es).

This approach will not work with Logic App Consumption





Services Used





1. Create Virtual Network




2. Create Logic App Standard




3. Create a workflow within the Logic App and set up an outbound HTTP action. 

This external website returns the IP address of the caller. This step mimics the HTTP trigger function mentioned here:

4. Integrate the Virtual Network Integration on the Logic App and select the VNET/subnet that was created in Step 1.





5. (Optional) Test without the NAT Gateway Linked



Navigate to the Networking blade of the Logic App and click on the list of Outbound IP addresses to view the full set. The IP address returned is part of the list.





6. Create NAT Gateway and integrate it to the Virtual Network


These below steps can be done during or after creation:

  1. Link the NAT Gateway to the Virtual Network and subnet that is configured on the Logic App.
  2. Create a Public IP Address, which will act as the outbound IP address.




Check to see what the IP address has been created. The Outbound IP address is this case is This is the static IP address. You can also create more IP addresses.




7. Test with the NAT Gateway Linked






Logic Apps Standard can be integrated with a Virtual Network, which in turn can be integrated with a NAT Gateway. This helps with routing traffic on built-in connectors through the NAT Gateway, using the static IP(s) defined as the outbound IP. In this tutorial, I have created only 1 static IP, but it is possible to create more on the NAT Gateway, which will allow the Logic App's traffic to route through either one.
