| # 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" | |
| ``` |
