1. Select **Networking**.

1. Leave the **Router IPs**, **SSH Proxy IPs**, **HAProxy IPs**, and **TCP Router IPs** fields blank. You do not need to complete these fields when deploying PCF to GCP. 
   <p class="note"><strong>Note</strong>: You specify load balancers in the **Resource Config** section of Elastic Runtime later on in the installation process. See the <a href="#config-lb">Configure Load Balancers</a> section of this topic for more information.</p>

1. Under **Select one of the following point-of-entry options**, choose the **Forward SSL to Elastic Runtime Router** option.
   <p class="note"><strong>Note</strong>: As a clarification, GCP load balancers actually forward both encrypted (WebSockets) and unencrypted (HTTP and TLS-terminated HTTPS) traffic to the Elastic Runtime Router (Gorouter). This point-of-entry selection accommodates this specific characteristic of GCP deployments. For more details on network topology in GCP, see [Reference Architecture for Pivotal Cloud Foundry on GCP](../refarch/gcp/gcp_ref_arch.html).</p>

1. Complete the fields for the **Router SSL Termination Certificate and Private Key** and **Router SSL Ciphers**.
For details about providing SSL termination certificates and keys, see the [Providing a Certificate for your SSL Termination Point](../opsguide/security_config.html#config) topic.

   1. For GCP, you also need to specify the name of a GCP TCP load balancer in the **LOAD BALANCER** column of TCP Router job of the **Resource Config** screen. You configure this later on in Elastic Runtime. See <a href="#configure-lb">Configure Load Balancers</a> section of this topic.</p>
