<p>So I have GCP set up and Kubernetes, I have a web app (Apache OFBiz) running on pods in the GKE cluster. We have a domain that points itself to the web app, so essentially it's accessible from anywhere on the internet. Our issue is since this is a school project, we want to limit the access to the web app to the internal network on GCP, we want to simulate a VPN connection. I have a VPN gateway set up, but I have no idea what to do on any random computer to simulate a connection to the internal network on GCP. Do I need something else to make this work? What are the steps on the host to connect to GCP? And finally, how do I go about limiting access to the webapp so only people in the internal network have access to the webapp?</p>

<p>When I want to test a VPN, I simply create a new VPC in my project and I connect both with Cloud VPN. Then, in the new VPC, you can create VM that simulate computer in the other side of the VPN and thus simulate what you want.</p>
