Terraform module to provision a site-to-site VPN connection between a VPC and an on-premises network.
The module does the following:
- Creates a Virtual Private Gateway (VPG) and attaches it to the VPC
- Creates a Customer Gateway (CGW) pointing to the provided IP address of the Internet-routable external interface on the on-premises network
- Creates a Site-to-Site Virtual Private Network (VPN) connection and assigns it to the VPG and CGW
- Requests automatic route propagation between the VPG and the provided route tables in the VPC
- If the VPN connection is configured to use static routes, provisions a static route between the VPN connection and the CGW
This project is part of our comprehensive "SweetOps" approach towards DevOps.
It's 100% Open Source and licensed under the APACHE2.
We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!
Security scanning is graciously provided by Bridgecrew. Bridgecrew is the leading fully hosted, cloud-native solution providing continuous Terraform security and compliance.

IMPORTANT: We do not pin modules to versions in our examples because of the difficulty of keeping the versions in the documentation in sync with the latest released versions. We highly recommend that in your code you pin the version to the exact version you are using so that your infrastructure remains stable, and update versions in a systematic way so that they do not catch you by surprise.
Also, because of a bug in the Terraform registry (hashicorp/terraform#21417), the registry shows many of our inputs as required when in fact they are optional. The table below correctly indicates which inputs are required.
module "vpn_connection" {
source = "cloudposse/vpn-connection/aws"
# Cloud Posse recommends pinning every module to a specific version
# version = "x.x.x"
namespace = "eg"
stage = "dev"
name = "test"
vpc_id = "vpc-xxxxxxxx"
vpn_gateway_amazon_side_asn = 64512
customer_gateway_bgp_asn = 65000
customer_gateway_ip_address = "172.0.0.1"
