In this lab, we will make private connection from Database server to Cloud server through the internet enviroment, using Site-to-Site VPN on AWS service. And the server inside Cloud server can connect to Internet via NAT Gateway.
We will use LibreSwan to establish IPsec VPN connections for the Data Server as a Customer Gateway on AWS EC2 in this lab. You can use various methods to connect to the AWS VPN, such as simulating on VMware, EVE-NG,… or using physical routing devices that support VPNs.
