Creating Site-to-Site connection between two Regions on Azure

Question

Hi,

I was trying for Site-to-Site connection between two Region (Central US and East US) on Azure.

VM is also created in both Region.

In one Region; I created Virtual Network Gateway and in another Region, I created Static Public IP and Local Network Gateway.

Using Connections, I added a Site-to-Site connection. Once the connection created, I see Download configuration.

When I downloaded it, it’s a text file containing various details.

Please let me know, how to use and where to use these details so that the connection can be established?

With Regards

Greetings,

This article walks you through downloading VPN device configuration scripts for S2S VPN connections with Azure VPN Gateways using Azure Resource Manager. This feature allows you to download a configuration script for your VPN device with the corresponding values of your Azure VPN gateway, virtual network, and on-premises network address prefixes, and VPN connection properties, etc. already filled in. You can use the script as a starting point, or apply the script directly to your on-premises VPN devices via the configuration console.

Thank you for replying me for my question.

The link shared by you explains, how to download S2S configuration scripts from the Azure Portal.

I mentioned in the question. I already downloaded it. This is a text file.

I don’t know which part of it to be used in another Region?

Pls let me know.

I am sharing the dashboard of both Resource Group. I downloaded the Configuration Script which is a text file. I don’t know, how to use it so that connection can be established.

If you prefer to connect your VNets by using a Site-to-Site connection then you no need to download the configuration script to establish connection instead follow the Site-to-Site IPsec steps, you create and configure the local network gateways manually. The local network gateway for each VNet treats the other VNet as a local site. These steps allow you to specify additional address spaces for the local network gateway to route traffic. If the address space for a VNet changes, you must manually update the corresponding local network gateway.
