Introducing AWS S2S VPN: A Bridge to the Cloud
An S2S VPN is a type of virtual private network that enables secure connectivity between two or more networks over a public network, typically the internet. In the realm of AWS, S2S VPN serves as a secure conduit, bridging the gap between your on-premises infrastructure and the vast array of AWS cloud services. By leveraging the robust security mechanisms of AWS, S2S VPNs ensure that data traversing between your premises and the cloud remains shielded from unauthorized access.
Prerequisites for AWS S2S VPN Setup
Before delving into the intricacies of AWS S2S VPN setup, it’s essential to gather the necessary prerequisites. These include:
- AWS account with necessary permissions
- Preconfigured on-premises infrastructure with a public IP address
- Virtual private gateway (VGW) within your AWS account
- Customer gateway (CGW) within your on-premises infrastructure
- Internet connectivity between the on-premises network and AWS
Step-by-Step Guide to AWS S2S VPN Setup
With the prerequisites in place, let’s embark on a step-by-step journey through AWS S2S VPN setup:
1. Create a VGW in AWS
Log into the AWS Management Console and navigate to the VPC section. Click on “Virtual Private Gateways” and select “Create Virtual Private Gateway.” Configure the VGW with the appropriate settings, including name, type, availability zone, and routing table.
2. Create a CGW in Your On-Premises Network
Configure the CGW on your on-premises router or firewall. Assign a public IP address, determine the IP address ranges of the on-premises network, and establish the necessary access and authentication parameters.
3. Establish a VPN Connection
In the AWS Management Console, navigate to “VPN Connections” and select “Create VPN Connection.” Enter a connection name, select the VGW created in step 1, and specify the IP address of the CGW. Configure encryption and authentication settings for secure data transmission.
4. Attach VGW and CGW to the VPN Connection
Associate the VGW and CGW with the VPN connection. This establishes a secure tunnel between your on-premises network and the AWS cloud.
5. Propagate Static Routes
Update the routing tables of both the VGW and CGW to advertise the IP address ranges of the on-premises network and AWS VPC, respectively. This ensures proper routing of traffic between the two networks.
