How to Configure VPN for VPC

Instances in your data center cannot communicate securely to instances in the VPC by default. But by configuring three methods discussed below you can provide the connectivity. There are three components of a VPN connection which are as follows:

  • Virtual Private Gateway (VGW) is a part of the VPN connection on the AWS side. AWS provides two redundant IPSec tunnels in the VPC to provide high availability.
  • Customer Gateway (CGW) is a part of the VPN connection on the data center. To have redundant connections for high availability, we need multiple CGWs configured in the data center. It will ensure continuous connectivity, even if one fails.
  • VPN connection that connects between VGW and CGW.

Task:

  • Configure the VPN Gateway names as DCLESSONS-VPNG-1
  • Once VPN gateway is configured attach it to VPC to make it VGW.
  • Create Customer Gateway named as DCLESSONS-CGW-1 and IP address of your DC subnet 192.38.1.10
  • Create the VPN connection name DCLESSONS-VPN-CONNECTION-1 and select both VPN gateway and CGW gateway and provide the CIDR for VPN 10.0.0.0/16
  • Download the configuration file while choosing the Vendor platform and which will be used for configuration on DC site Router.
