Dokumen ini menunjukkan cara menetapkan alamat IP perusahaan Anda sendiri, atau
alamat IP Google Cloud statis, yang digunakan Secure Web Proxy untuk traffic keluar.
Pastikan Anda memiliki daftar alamat IPv4 statis yang dicadangkan untuk digunakan bagi Proxy Web Aman. Jika Anda ingin mencadangkan alamat IP di Google Cloud, lihat
perintah gcloud compute addresses create untuk membuat resource alamat.
Pastikan Anda telah menginstal Google Cloud CLI versi 406.0.0 atau yang lebih baru:
gcloud version | head -n1
Jika Anda telah menginstal versi gcloud CLI sebelumnya, update versinya:
gcloud components update --version=406.0.0
Mengaktifkan alamat IP statis untuk Secure Web Proxy
Lakukan tindakan berikut:
Identifikasi nama Cloud Router yang ditetapkan selama penyediaan Proxy Web Aman:
gcloud compute routers list \
--region REGION \
--filter="network:(NETWORK_NAME) AND name:(swg-autogen-router-*)" \
--format="get(name)"
Ganti kode berikut:
REGION: region tempat Cloud Router di-deploy untuk Proxy Web Aman
NETWORK_NAME: nama jaringan VPC
Anda
Outputnya mirip dengan hal berikut ini:
swg-autogen-router-1
Cantumkan alamat IP eksternal yang disediakan secara otomatis dan ditetapkan selama
penyediaan Secure Web Proxy:
Perbarui gateway Cloud NAT untuk menggunakan mode Dynamic Port Allocation (DPA). Mode DPA memungkinkan Secure Web Proxy menggunakan alamat IP yang ditetapkan sepenuhnya.

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.

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.
