How do create a VPN with Amazon VPC
You might need to create a secure VPN Connection between your office and cloud using AWS VPN service. I am showing here three main component to build this connection. Three main component are:
1. Customer Gateways: This represent the customer office site connection. Here you need to specify your on-premises firewall public IP and routing type dynamic routing (BGP) or static routing
2. Virtial Private Gateways: This represent VPN endpoint of AWS site connection.
3. VPN Connection: This is based on the avobe two component which will provide downloadable configuration file that you can use to configure office firewall.
