The module is designed to be flexible and can be used in a variety of scenarios.\n\n- If you supply `customer_gateway_ip_address` and set `transit_gateway_enabled` to `true`, \n  the module will create a CGW, then create a VPN connection, and then assign the connection to\n  the Transit Gateway identified by `existing_transit_gateway_id` and the created CGW\n- If you supply `customer_gateway_ip_address` and set `transit_gateway_enabled` to `false`,\n  the module will create a VPG and CGW, then create a VPN connection, and then assign it to the VPG and CGW\n- If you do not supply `customer_gateway_ip_address` (set it to `null`) then the module will only create a VPG\n\nThe module also provides some options for adding routes to the VPC or TGW route tables. You need to use\nthe options that correspond to the kind of attachment point (VPC or TGW) you are using.\n\n\n\u003e [!TIP]\n\u003e #### 👽 Use Atmos with Terraform\n\u003e Cloud Posse uses [`atmos`](https://atmos.tools) to easily orchestrate multiple environments using Terraform. \u003cbr/\u003e\n\u003e Works with [Github Actions](https://atmos.tools/integrations/github-actions/), [Atlantis](https://atmos.tools/integrations/atlantis), or [Spacelift](https://atmos.tools/integrations/spacelift).\n\u003e\n\u003e \u003cdetails\u003e\n\u003e \u003csummary\u003e\u003cstrong\u003eWatch demo of using Atmos with Terraform\u003c/strong\u003e\u003c/summary\u003e\n\u003e \u003cimg src=\"https://github.com/cloudposse/atmos/blob/main/docs/demo.gif?raw=true\"/\u003e\u003cbr/\u003e\n\u003e \u003ci\u003eExample of running \u003ca href=\"https://atmos.tools\"\u003e\u003ccode\u003eatmos\u003c/code\u003e\u003c/a\u003e to manage infrastructure from our \u003ca href=\"https://atmos.tools/quick-start/\"\u003eQuick Start\u003c/a\u003e tutorial.\u003c/i\u003e\n\u003e \u003c/detalis\u003e\n\n\n\n\n\n## Usage\n\n```hcl\n  module \"vpn_connection\" {\n    source = \"cloudposse/vpn-connection/aws\"\n    # Cloud Posse recommends pinning every module to a specific version\n    # version = \"x.x.x\"\n    namespace                                 = \"eg\"\n    stage                                     = \"dev\"\n    name                                      = \"test\"\n    vpc_id                                    = \"vpc-xxxxxxxx\"\n    vpn_gateway_amazon_side_asn               = 64512\n    customer_gateway_bgp_asn                  = 65000\n    customer_gateway_ip_address               = \"172.0.0.1\"\n    route_table_ids                           = [\"rtb-xxxxxxxx\", \"rtb-yyyyyyyy\", \"rtb-zzzzzzzz\"]\n    vpn_connection_static_routes_only         = \"true\"\n    vpn_connection_static_routes_destinations = [\"10.80.1.0/24\"]\n  }\n```\n\n\u003e [!IMPORTANT]\n\u003e In Cloud Posse's examples, we avoid pinning modules to specific versions to prevent discrepancies between the documentation\n\u003e and the latest released versions. However, for your own projects, we strongly advise pinning each module to the exact version\n\u003e you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic\n\u003e approach for updating versions to avoid unexpected changes.\n\n\n\n\n\n\n\n\n\u003c!-- markdownlint-disable --\u003e\n## Requirements\n\n| Name | Version |\n|------|---------|\n| \u003ca name=\"requirement_terraform\"\u003e\u003c/a\u003e [terraform](#requirement\\_terraform) | \u003e= 1.3.0 |\n| \u003ca name=\"requirement_aws\"\u003e\u003c/a\u003e [aws](#requirement\\_aws) | \u003e= 5.53.0 |\n\n## Providers\n\n| Name | Version |\n|------|---------|\n| \u003ca name=\"provider_aws\"\u003e\u003c/a\u003e [aws](#provider\\_aws) | \u003e= 5.53.0 |\n\n## Modules\n\n| Name | Source | Version |\n|------|--------|---------|\n| \u003ca name=\"module_logs\"\u003e\u003c/a\u003e [logs](#module\\_logs) | cloudposse/cloudwatch-logs/aws | 0.6.9 |\n| \u003ca name=\"module_this\"\u003e\u003c/a\u003e [this](#module\\_this) | cloudposse/label/null | 0.25.0 |\n\n## Resources\n\n| Name | Type |\n|------|------|\n| [aws_customer_gateway.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/customer_gateway) | resource |\n| [aws_ec2_tag.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/ec2_tag) | resource |\n| [aws_ec2_transit_gateway_route.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/ec2_transit_gateway_route) | resource |\n| [aws_ec2_transit_gateway_route_table_association.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/ec2_transit_gateway_route_table_association) | resource |\n| [aws_ec2_transit_gateway_route_table_propagation.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/ec2_transit_gateway_route_table_propagation) | resource |\n| [aws_vpn_connection.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/vpn_connection) | resource |\n| [aws_vpn_connection_route.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/vpn_connection_route) | resource |\n| [aws_vpn_gateway.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/vpn_gateway) | resource |\n| [aws_vpn_gateway_route_propagation.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/vpn_gateway_route_propagation) | resource |\n\n## Inputs\n\n| Name | Description | Type | Default | Required |\n|------|-------------|------|---------|:--------:|\n| \u003ca name=\"input_additional_tag_map\"\u003e\u003c/a\u003e [additional\\_tag\\_map](#input\\_additional\\_tag\\_map) | Additional key-value pairs to add to each map in `tags_as_list_of_maps`.

It centralizes configuration and wraps common test workflows with easy-to-use commands.\n\nAll tests are located in the [`test/`](test) folder.\n\nUnder the hood, tests are powered by Terratest together with our internal [Test Helpers](https://github.com/cloudposse/test-helpers) library, providing robust infrastructure validation.\n\nSetup dependencies:\n- Install Atmos ([installation guide](https://atmos.tools/install/))\n- Install Go [1.24+ or newer](https://go.dev/doc/install)\n- Install Terraform or OpenTofu\n\nTo run tests:\n\n- Run all tests:  \n  ```sh\n  atmos test run\n  ```\n- Clean up test artifacts:  \n  ```sh\n  atmos test clean\n  ```\n- Explore additional test options:  \n  ```sh\n  atmos test --help\n  ```\nThe configuration for test commands is centrally managed. To review what's being imported, see the [`atmos.yaml`](https://raw.githubusercontent.com/cloudposse/.github/refs/heads/main/.github/atmos/terraform-module.yaml) file.\n\nLearn more about our [automated testing in our documentation](https://docs.cloudposse.com/community/contribute/automated-testing/) or implementing [custom commands](https://atmos.tools/core-concepts/custom-commands/) with atmos.\n\n### 🌎 Slack Community\n\nJoin our [Open Source Community](https://cpco.io/slack?utm_source=github\u0026utm_medium=readme\u0026utm_campaign=cloudposse/terraform-aws-vpn-connection\u0026utm_content=slack) on Slack.
