Two of the components you need to connect to your VPC with a VPN connection are a virtual
private gateway on the VPC side and a customer gateway on the on-premise network side
VPC routers are not part of the VPN configuration
NAT instances are not used for VPN, they are used by EC2 instances in private subnets to
access the Internet
Direct Connect can be used to connect an on-premise network to the cloud however it is not
part of the configuration of an Amazon Managed VPN connection
