Extending your Private IP Space to GCP

Cloud VPN supports site-to-site VPN. You can have multiple tunnels to a single VPN gateway. In other words, you can connect multiple on-premises networks using multiple on-premises gateways to the same VPC network.

  • Cloud VPN supports both static routes and dynamic routes (via Cloud Router) for managing traffic between your instances and your existing infrastructure.
  • Uses IPSec (Gateway to Gateway).
  • Traffic traveling between the two networks is encrypted by one VPN gateway, then decrypted by the other VPN gateway.

Connecting Existing GCP Networks/Projects together using CloudVPN

  • Create a dedicated network for Google Compute Engine instances you want to connect via VPN in project A. This will be our project-a-network. Choose an address range in one of the private IP address ranges. We will use a class C network with over 65k addresses for our example.
  • Set up the VPN connection in each of your projects with a dedicated endpoint IP address
