IPSec VPN in AWS

To configure IPSec VPN in AWS, follow these steps:


Step 1. Create a Virtual Private Gateway (VGW): The VGW is the AWS side of the VPN connection. To create a VGW, go to the VPC dashboard in the AWS console and select "Virtual Private Gateways" from the left-hand menu. Click on "Create Virtual Private Gateway" and follow the prompts to configure the VGW.


Step 2. Create a Customer Gateway (CGW): The CGW is the on-premises side of the VPN connection. To create a CGW, go to the VPC dashboard in the AWS console and select "Customer Gateways" from the left-hand menu. Click on "Create Customer Gateway" and follow the prompts to configure the CGW.


Step 3. Create a VPN Connection: Once you have created the VGW and CGW, you can create a VPN connection between them. To do this, go to the VPC dashboard in the AWS console and select "VPN Connections" from the left-hand menu. Click on "Create VPN Connection" and follow the prompts to configure the VPN connection.


Step 4. Configure the on-premises VPN device: You will need to configure your on-premises VPN device to establish the VPN connection with the VGW. The exact configuration steps will depend on the VPN device you are using.


Step 5. Test the VPN Connection: Once you have configured the VPN connection, you should test it to ensure that it is working properly. You can do this by pinging an instance in your VPC from your on-premises network, and vice versa.


That's it! You have successfully configured IPSec VPN in AWS.
