为部署安全 Web 代理的每个区域创建代理子网。创建至少为 /26 的子网大小，即 64 个代理专用地址。我们建议子网大小为 /23（即 512 个代理专用地址），因为安全 Web 代理连接由为安全 Web 代理预留的 IP 地址池提供。此池用于在每个代理的出站端分配唯一的 IP 地址，以便与 Cloud NAT 和 VPC 网络中的目的地进行交互。

Optional: If you have a set of users responsible for ongoing policy\n management, grant them the Security Policy Admin role\n (`roles/compute.orgSecurityPolicyAdmin`) to let them manage security\n policies.\n\nCreate a Google Cloud project\n\nTo create or select a Google Cloud project, follow these steps: \n\nConsole\n\nIn the Google Cloud console, on the project selector page, select or\n[create a Google Cloud project](/resource-manager/docs/creating-managing-projects).\n\n[Go to project selector](https://console.cloud.google.com/projectselector2/home/dashboard)\n\nCloud Shell\n\n- Create a Google Cloud project:\n\n gcloud projects create \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e\n\n Replace \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e with the project ID that you\n want.\n- Select the Google Cloud project that you created:\n\n gcloud config set project \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e\n\nEnable billing\n\nMake sure that billing is enabled for your Google Cloud project. For more\ninformation, see [Enable, disable, or change billing for a project](/billing/docs/how-to/modify-project)\nand [Verify the billing status of your projects](/billing/docs/how-to/verify-billing-enabled).\n\nEnable the required APIs\n\nYou must enable the following Google Cloud APIs:\n\n- `compute.googleapis.com`\n- `certificatemanager.googleapis.com`\n- `networkservices.googleapis.com`\n- `networksecurity.googleapis.com`\n- `privateca.googleapis.com` (optional)\n\nTo enable the required Google Cloud APIs, do the following: \n\nConsole\n\n1. Enable the Compute Engine API.\n\n [Enable the API](https://console.cloud.google.com/apis/enableflow?apiid=compute)\n2. Enable the Certificate Manager API.\n\n [Enable the API](https://console.cloud.google.com/apis/enableflow?apiid=certificatemanager)\n3. Enable the Network Services API.\n\n [Enable the API](https://console.cloud.google.com/apis/enableflow?apiid=networkservices)\n4. Enable the Network Security API.\n\n [Enable the API](https://console.cloud.google.com/apis/enableflow?apiid=networksecurity)\n5. Optional: If you plan to [configure TLS inspection](/secure-web-proxy/docs/enable-tls-inspection)\n for your proxy, then you must enable the Certificate Authority Service API.\n\n [Enable the API](https://console.cloud.google.com/apis/enableflow?apiid=privateca)\n\ngcloud\n\nRun the following command: \n\n```\n gcloud services enable \\\n --compute.googleapis.com \\\n --certificatemanager.googleapis.com \\\n --networkservices.googleapis.com \\\n --networksecurity.googleapis.com \\\n --privateca.googleapis.com\n```\n\nCreate a proxy subnet\n\nCreate a proxy subnet for each region that you deploy Secure Web Proxy in.\nCreate a subnet size of at least /26, or 64 proxy-only addresses. We recommend\na subnet size of /23, or 512 proxy-only addresses, because Secure Web Proxy\nconnectivity is provided by a pool of IP addresses reserved for\nSecure Web Proxy. This pool is used to allocate unique IP addresses on the\negress side of each proxy for interaction with Cloud NAT and destinations in\nthe VPC network.\n**Important:** This subnet is *not* referenced when creating a Secure Web Proxy instance. For more information, see [Proxy-only subnets for Envoy-based load balancers](/load-balancing/docs/proxy-only-subnets). \n\ngcloud \n\n gcloud compute networks subnets create \u003cvar translate=\"no\"\u003ePROXY_SUBNET_NAME\u003c/var\u003e \\\n --purpose=REGIONAL_MANAGED_PROXY \\\n --role=ACTIVE \\\n --region=\u003cvar translate=\"no\"\u003eREGION\u003c/var\u003e \\\n --network=\u003cvar translate=\"no\"\u003eNETWORK_NAME\u003c/var\u003e \\\n --range=\u003cvar translate=\"no\"\u003eIP_RANGE\u003c/var\u003e\n\nReplace the following:\n\n- \u003cvar translate=\"no\"\u003ePROXY_SUBNET_NAME\u003c/var\u003e: the name that you want for your proxy subnet\n- \u003cvar translate=\"no\"\u003eREGION\u003c/var\u003e: the region to deploy the proxy subnet in\n- \u003cvar translate=\"no\"\u003eNETWORK_NAME\u003c/var\u003e: your network name\n- \u003cvar translate=\"no\"\u003eIP_RANGE\u003c/var\u003e: the subnet range, such as `192.168.0.0/23`\n\nDeploy an SSL certificate\n\nSSL certificates are optional for Secure Web Proxy. To deploy certificates\nusing Certificate Manager, use any of the following methods:\n\n- Deploy a regional Google-managed certificate with per-project DNS\n authorization. For more information, see [Deploy a regional Google-managed certificate](/certificate-manager/docs/deploy-google-managed-regional).\n\n- Deploy a regional Google-managed certificate with Certificate Authority Service. For\n more information, see [Deploy a regional Google-managed certificate with CA Service](/certificate-manager/docs/deploy-google-managed-cas-regional).\n\n- Deploy a regional self-managed certificate.\n\n The following example shows how to deploy a regional self-managed certificate using Certificate Manager.\n\n \u003cbr /\u003e\n\n1. To create an SSL certificate:\n\n openssl req -x509 -newkey rsa:2048 \\\n -keyout \u003cvar translate=\"no\"\u003eKEY_PATH\u003c/var\u003e \\\n -out \u003cvar translate=\"no\"\u003eCERTIFICATE_PATH\u003c/var\u003e -days 365 \\\n -subj '/CN=\u003cvar translate=\"no\"\u003eSWP_HOST_NAME\u003c/var\u003e' -nodes -addext \\\n \"subjectAltName=DNS:\u003cvar translate=\"no\"\u003eSWP_HOST_NAME\u003c/var\u003e\"\n\n Replace the following:\n - \u003cvar translate=\"no\"\u003eKEY_PATH\u003c/var\u003e: the path to save the key, such as `~/key.pem`\n - \u003cvar translate=\"no\"\u003eCERTIFICATE_PATH\u003c/var\u003e: the path to save the certificate, such as `~/cert.pem`\n - \u003cvar translate=\"no\"\u003eSWP_HOST_NAME\u003c/var\u003e: the hostname for your Secure Web Proxy instance, such as `myswp.example.com`\n2.
