How one can create a Web site-to-Web site VPN in CloudFormation


To create a site-to-site VPN (Digital Personal Community) utilizing AWS CloudFormation, you should utilize the AWS::EC2::VPNGateway and AWS::EC2::VPNConnection assets. Right here’s an instance CloudFormation template to create a site-to-site VPN:

AWSTemplateFormatVersion: '2010-09-09'
Sources:
  VpnGateway:
    Kind: AWS::EC2::VPNGateway
    Properties:
      Kind: ipsec.1
      Tags:
        - Key: Identify
          Worth: SiteToSiteVPN

  VpnConnection:
    Kind: AWS::EC2::VPNConnection
    Properties:
      Kind: ipsec.1
      CustomerGatewayId: <CUSTOMER_GATEWAY_ID>
      VpnGatewayId: !Ref VpnGateway
      StaticRoutesOnly: true
      Tags:
        - Key: Identify
          Worth: SiteToSiteVPNConnection

  VpnConnectionRoute:
    Kind: AWS::EC2::VPNConnectionRoute
    Properties:
      DestinationCidrBlock: <DESTINATION_CIDR_BLOCK>
      VpnConnectionId: !Ref VpnConnection

Within the above template, you have to substitute <CUSTOMER_GATEWAY_ID> with the ID of the client gateway representing the distant web site, and <DESTINATION_CIDR_BLOCK> with the CIDR block of the distant community you wish to hook up with.

This template creates a VPN gateway (VpnGateway) and a VPN connection (VpnConnection). It additionally creates a VPN connection route (VpnConnectionRoute) to specify the vacation spot CIDR block that ought to be routed by the VPN connection.

Observe that you could be want to switch the template primarily based in your particular necessities, akin to configuring the client gateway or making extra community changes.

Upon getting the CloudFormation template prepared, you’ll be able to create the stack utilizing the AWS CloudFormation console, AWS CLI, or AWS SDKs. The stack creation course of will provision the required assets to ascertain the site-to-site VPN connection.
