In today's interconnected world, organizations often need to establish secure and reliable communication between their on-premises network and their cloud infrastructure. A popular solution to achieve this is by setting up a Site-to-Site Virtual Private Network (VPN) in Amazon Web Services (AWS).
A Site-to-Site VPN allows organizations to extend their on-premises network to AWS, creating a secure channel for data transfer and seamless communication between the two. In this blog post, we will guide you through the process of setting up a Site-to-Site VPN in AWS. Let's get started!
Step 1: Configure a Virtual Private Gateway (VGW)
The first step is to configure a Virtual Private Gateway (VGW). This gateway acts as the communication hub between the on-premises network and VPC (Virtual Private Cloud) in AWS. To configure VGW, follow these steps:
Go to the AWS Management Console and navigate to the VPC service.
Click on "Virtual Private Gateways" in the left-hand panel.
Click on "Create Virtual Private Gateway" and follow the prompts to configure it.
Step 2: Create a Customer Gateway
A Customer Gateway represents clients' on-premises network and is responsible for establishing a connection to the VGW in AWS. To create a Customer Gateway, follow these steps:
In the AWS Management Console, navigate to the VPC service.
Click on "Customer Gateways" in the left-hand panel.
Click on "Create Customer Gateway" and provide the necessary details, including the public IP address of the on-premises router.
Step 3: Create a Site-to-Site VPN Connection
After configuring VGW and Customer Gateway, it's time to create a Site-to-Site VPN connection. This connection establishes the secure tunnel between the on-premises network and VPC. To create a Site-to-Site VPN connection, follow these steps:
In the AWS Management Console, navigate to the VPC service.
Click on "Site-to-Site VPN Connections" in the left-hand panel.
Click on "Create VPN Connection" and provide the necessary details, including the VGW and Customer Gateway.
Configure the tunnel options and specify the IP address of the remote router for the on-premises network.
Step 4: Update Routing Table
The final step is to update the routing table to ensure traffic between the on-premises network and VPC flows through the VPN connection. To update the routing table, follow these steps:
In the AWS Management Console, navigate to the VPC service.
Click on "Routing Tables" in the left-hand panel.
Select the routing table associated with your VPC and click the "Routes" tab.
Add a new route that points to the Site-to-Site VPN connection as the target.
Congratulations! You have successfully set up a Site-to-Site VPN in AWS. On-premises network can now securely communicate with VPC in AWS, allowing clients to leverage the benefits of the cloud while maintaining the privacy and security of their data.
How to Setup Site to Site VPN in AWS
Setup an IPSec tunnel Site-to-Site VPN between AWS and Azure. Using OpenSwan VPN appliance, we can create IPsec tunnels between different clouds environments. This video will guide you to connect AWS and Azure over VPN tunnels.
In conclusion, a Site-to-Site VPN is essential to creating a hybrid network environment that seamlessly connects on-premises network with AWS infrastructure. Following the steps outlined in this blog post, establish a secure and reliable connection between the two, enabling data transfer and communication without compromising security.
