# Google Compute Engine VPN Example This example joins two GCE networks via VPN. The firewall rules have been set up so that you can create an instance in each network and have them communicate using their internal IP addresses. See this [example](https://cloud.google.com/compute/docs/vpn) for more information. Run this example using ``` terraform apply \ -var="region1=us-central1" \ -var="region2=europe-west1" \ -var="project=my-project-id-123" ```
