![]() ![]() It has support for many cloud provider, and obviously, Google Cloud Platform is one of them.Īfter creating a Service Account key file (more info here), you are only one command away from having an inlets PRO server: ![]() The fastest way to create such an exit-node is using a handy utility inletsctl, which automates the task of creating the server node on cloud infrastructure. Inlets PRO exit-node running on Google Cloud Platform All traffic is sent over an encrypted WebSocket using HTTPS which works well with HTTP proxies, VPNs, and VM networks. The interesting part is that it is using somehow the same techniques as the Cloud IAP.Īn inlets PRO client establishes an outbound connection an inlets PRO server over HTTPS. In fact, you could use any cloud provider to create a public exit-node for your services. The Cloud Native Tunnel for L4 TCP traffic, inlets PRO, is independent of Google Cloud. One extra step would be enabling Cloud Audit logs for IAP, which lets you view a request and see all the access levels a user has and hasn’t met. All ingress traffic is blocked by the firewall, except if coming from IAP, making it a secure setup. Only users with the correct IAM permissions can access your service from any location via the Cloud Identity-Aware Proxy with those two steps. Gcloud projects add-iam-policy-binding PROJECT_ID \ With the following command, we bring the database service to our local machine: Conversely, any data from the remote port is also wrapped before it’s sent to the local port where it’s then unwrapped.Ī PostgreSQL server protected by Google IAPĪs an example, let’s say we have a PostgreSQL server running on a GCE VM instance, named my-postgres-vm. IAP then receives the data, applies access controls, and forwards the unwrapped data to the remote port. The local port tunnels data traffic from the local machine to the remote machine in an HTTPS stream. You can use IAP TCP forwarding for other TCP-based protocols by using the gcloud compute start-iap-tunnel command to allocate a local port. So what does the IAP TCP forwarding looks like? Forwarding TCP traffic with IAP allows you to reduce that risk, ensuring only authorized users gain access to these sensitive services. Inlets PRO is the perfect fit to make such administrative services available with a public endpoint, but exposing them directly to the internet introduces risk. ![]() Or you want to expose administrative services such as Grafana dashboards or PostgreSQL’s admin interface. Perhaps you would like to give SSH access to some internal servers from anywhere. I’m sure the combination will be useful in many use cases. What if we could combine Google IAP and inlets? In other words, can we use Google Cloud Identity-Aware Proxy and inlets to create context-aware access control for our on-premises services? By running the server part of the tunnel, also known as an exit-node, on a Google Compute Engine instance, and connecting a client running in a private datacenter, your private services become available for your employees or customers from anywhere without the hassle of VPNs. As it is Cloud Native by design, it can run on containers or VMs. It allows you to tunnel your private service to a remote network, or get a public IP and serve traffic to your users. Inlets PRO is a Software Defined Network (SDN) for connecting applications. As part of the BeyondCorp security model, it enables context-aware access from virtually any location to your applications or VMs without the need for bastion hosts or a traditional VPN. Google Cloud Identity-aware Proxy, or in short IAP, is an access control tool on the Google Cloud Platform for controlling access based on who is making an HTTP request to your application or who is making SSH connections to your virtual servers. ![]() Photo by Scott Webb on Unsplash Introduction ![]()
