En este documento, se muestra cómo asignar tus propias direcciones IP de la empresa o direcciones IP Google Cloud estáticas que usa el proxy web seguro para el tráfico de salida.
Asegúrate de tener una lista de direcciones IPv4 estáticas reservadas para usar en el proxy web seguro. Si quieres reservar direcciones IP en Google Cloud, consulta el comando gcloud compute addresses create para crear un recurso de dirección.
Verifica que tengas instalada la versión 406.0.0 o posterior de Google Cloud CLI:
gcloud version | head -n1
Si tienes instalada una versión anterior de gcloud CLI, actualiza la versión:
gcloud components update --version=406.0.0
Habilita las direcciones IP estáticas para el proxy web seguro
Puedes hacer lo siguiente:
Identifica el nombre de Cloud Router asignado durante el aprovisionamiento del Proxy web seguro:
gcloud compute routers list \
--region REGION \
--filter="network:(NETWORK_NAME) AND name:(swg-autogen-router-*)" \
--format="get(name)"
Reemplaza lo siguiente:
REGION: Es la región en la que se implementa el Cloud Router para el proxy web seguro.
NETWORK_NAME: Es el nombre de tu red de VPC.
El resultado es similar a este:
swg-autogen-router-1
Haz una lista de las direcciones IP externas aprovisionadas automáticamente asignadas durante el aprovisionamiento del proxy web seguro:
Actualiza la puerta de enlace de Cloud NAT para usar el modo de asignación dinámica de puertos (DPA). El modo DPA permite que el Proxy web seguro use por completo las direcciones IP asignadas.
Para las marcas --min-ports-per-vm y --max-ports-per-vm, te recomendamos que uses los valores 2048 y 4096, respectivamente.
Usa el Explorador de métricas para supervisar los datos de métricas de los siguientes elementos y ajustar los valores mínimos y máximos de la DPA según sea necesario:
Cloud NAT Gateway - Port usage
Cloud NAT Gateway - New connection count
Cloud NAT Gateway - Open connections
Verifica que la DPA esté habilitada y que los valores mínimos y máximos de puertos estén configurados:

If you want to reserve IP addresses in Google Cloud, see the\n [`gcloud compute addresses create` command](/sdk/gcloud/reference/compute/addresses/create) to create an address\n resource.\n\n- Verify that you have the Google Cloud CLI version 406.0.0 or later installed:\n\n gcloud version | head -n1\n\n If you have an earlier gcloud CLI version installed, update the version: \n\n gcloud components update --version=406.0.0\n\nEnable static IP addresses for Secure Web Proxy\n-----------------------------------------------\n\nDo the following:\n\n1. Identify the Cloud Router name assigned during Secure Web Proxy\n provisioning:\n\n gcloud compute routers list \\\n --region \u003cvar translate=\"no\"\u003eREGION\u003c/var\u003e \\\n --filter=\"network:(\u003cvar translate=\"no\"\u003eNETWORK_NAME\u003c/var\u003e) AND name:(swg-autogen-router-*)\" \\\n --format=\"get(name)\"\n\n Replace the following:\n - \u003cvar translate=\"no\"\u003eREGION\u003c/var\u003e: the region that the Cloud Router is deployed for Secure Web Proxy\n - \u003cvar translate=\"no\"\u003eNETWORK_NAME\u003c/var\u003e: the name of your VPC network\n\n The output is similar to the following: \n\n swg-autogen-router-1\n\n2. List the external automatically provisioned IP addresses assigned during\n Secure Web Proxy provisioning:\n\n gcloud compute routers get-status \u003cvar translate=\"no\"\u003eROUTER_NAME\u003c/var\u003e \\\n --region=\u003cvar translate=\"no\"\u003eREGION\u003c/var\u003e\n\n The output is similar to the following: \n\n kind: compute#routerStatusResponse\n result:\n natStatus:\n - autoAllocatedNatIps:\n - 34.144.80.46\n - 34.144.83.75\n - 34.144.88.111\n - 34.144.94.113\n minExtraNatIpsNeeded: 0\n name: swg-autogen-nat\n numVmEndpointsWithNatMappings: 3\n network: https://www.googleapis.com/compute/projects/PROJECT_NAME/global/networks/NETWORK_NAME\n\n | **Note:** In the preceding output, the `swg-autogen-nat` Cloud NAT gateway has four automatically provisioned IP addresses. The Secure Web Proxy can scale up or scale down automatically provisioned Cloud NAT IP addresses based on your Google Cloud workload.\n3. Update the Cloud NAT gateway to use your predefined IP range:\n\n gcloud compute routers nats update swg-autogen-nat \\\n --router=\u003cvar translate=\"no\"\u003eROUTER_NAME\u003c/var\u003e \\\n --nat-external-ip-pool=\u003cvar translate=\"no\"\u003eIPv4_ADDRESSES\u003c/var\u003e... \\\n --region=\u003cvar translate=\"no\"\u003eREGION\u003c/var\u003e\n\n Replace \u003cvar translate=\"no\"\u003eIPv4_ADDRESSES\u003c/var\u003e with the name of the external\n IPv4 address resource that you intend to use, separated by a comma (`,`).\n4. Verify that your IP range is assigned to the Cloud NAT gateway:\n\n gcloud compute routers nats describe swg-autogen-nat \\\n --router=\u003cvar translate=\"no\"\u003eROUTER_NAME\u003c/var\u003e \\\n --region=\u003cvar translate=\"no\"\u003eREGION\u003c/var\u003e\n\n The output is similar to the following: \n\n enableEndpointIndependentMapping: false\n icmpIdleTimeoutSec: 30\n logConfig:\n enable: false\n filter: ALL\n name: swg-autogen-nat\n natIpAllocateOption: MANUAL_ONLY\n natIps:\n - https://www.googleapis.com/compute/projects/PROJECT_NAME/regions/REGION/addresses/ADDRESS\n sourceSubnetworkIpRangesToNat: ALL_SUBNETWORKS_ALL_IP_RANGES\n\n5. Update the Cloud NAT gateway to use Dynamic Port Allocation (DPA)\n mode. DPA mode allows Secure Web Proxy to fully use the assigned IP\n addresses.\n\n gcloud compute routers nats update swg-autogen-nat \\\n --router=\u003cvar translate=\"no\"\u003eROUTER_NAME\u003c/var\u003e \\\n --min-ports-per-vm=2048 \\\n --max-ports-per-vm=4096 \\\n --enable-dynamic-port-allocation \\\n --region=\u003cvar translate=\"no\"\u003eREGION\u003c/var\u003e\n\n For `--min-ports-per-vm` and `--max-ports-per-vm` flags, we recommend that\n you use values `2048` and `4096`, respectively.\n\n Use [Metrics Explorer](https://cloud.google.com/monitoring/charts/metrics-selector#basic-advanced-mode)\n to monitor metrics data for the following and adjust DPA minimum and maximum\n values as needed:\n - `Cloud NAT Gateway - Port usage`\n - `Cloud NAT Gateway - New connection count`\n - `Cloud NAT Gateway - Open connections`\n6.
