This component provisions a Site-To-Site VPN with a target AWS VPC on one side of the tunnel. The other (customer) side can be any VPN gateway endpoint, e.g. a hardware device, other cloud VPN, etc.

AWS Site-to-Site VPN is a fully-managed service that creates a secure connection between your data center or branch office and your AWS resources using IP Security (IPSec) tunnels. When using Site-to-Site VPN, you can connect to both your Amazon Virtual Private Clouds (VPC) and AWS Transit Gateway, and two tunnels per connection are used for increased redundancy.

The component provisions the following resources:

AWS Virtual Private Gateway (a representation of the AWS side of the tunnel)
AWS Customer Gateway (a representation of the other (remote) side of the tunnel). It requires:
- The gateway's Border Gateway Protocol (BGP) Autonomous System Number (ASN)
- /32 IP of the VPN endpoint
AWS Site-To-Site VPN connection. It creates two VPN tunnels for redundancy and requires:
- The IP CIDR ranges on each side of the tunnel
- Pre-shared Keys for each tunnel (can be auto-generated if not provided and saved into SSM Parameter Store)
- (Optional) IP CIDR ranges to be used inside each VPN tunnel
Route table entries to direct the appropriate traffic from the local VPC to the other side of the tunnel

Post-tunnel creation requirements

Once the site-to-site VPN resources are deployed, you need to send the VPN configuration from AWS side to the administrator of the remote side of the VPN connection. To do this:

Determine the infrastructure that will be used for the remote side, specifically:

Vendor
Platform
Software Version
IKE version

Log into the target AWS account
Go to the "VPC" console
On the left navigation manu, go to Virtual Private Network > Site-to-Site VPN Connections
Select the VPN connection that was created via this component
On the top right, click the Download Configuration button
Enter the information you obtained and click Download
Send the configuration file to the administrator of the remote side of the tunnel

Amazon side Autonomous System Number (ASN)

The variable vpn_gateway_amazon_side_asn (Amazon side Autonomous System Number) is not strictly required when creating an AWS VPN Gateway. If you do not specify Amazon side ASN during the creation of the VPN Gateway, AWS will automatically assign a default ASN (which is 7224 for the Amazon side of the VPN).

However, specifying Amazon side ASN can be important if you need to integrate the VPN with an on-premises network that uses Border Gateway Protocol (BGP) and you want to avoid ASN conflicts or require a specific ASN for routing policies.

If your use case involves BGP peering, and you need a specific ASN for the Amazon side, then you should explicitly set the vpn_gateway_amazon_side_asn. Otherwise, it can be omitted (set to null), and AWS will handle it automatically.

Provisioning

Provision the site-to-site-vpn component by executing the following commands:
