Your on-premise data center (172.16.128.0/24) is already connected to your AWS VPC (10.0.0.0/16) by a customer gateway. You wish to connect another data center for a company you just acquired (172.16.130.0/24) to your VPC as shown in the image. What is the best way to create this link?

  • Establish a connection between your two data centers and connect the second data center to the first through a private tunnel. Traffic will flow from the second data center and then through the first data, and then into AWS.
  • Create a second customer gateway and configure your VPN client at your second data center to connect to the virtual private gateway.
  • Create a second virtual private gateway (VPG) and attach it to the VPC. Create a customer gateway for the new virtual private gateway and use your VPN client at your second data center to establish a connection to the VPG.
  • You can not have more than one customer gateway per VPC, so the proposed solution will not work. Create a second VPC with a virtual private gateway and a customer gateway. Bridge the two VPCs using VPC peering.
