This guide shows how to set up a connector in the service project.\n\nIf you need to set up a connector in the host project, see\n[Configure connectors in the host project](/functions/1stgendocs/networking/shared-vpc-host-project).\nTo learn about the advantages of each method, see\n[Connecting to a Shared VPC network](/functions/1stgendocs/networking/connecting-shared-vpc).\n\nAt a high level, you must take the following steps:\n\n1. [Add firewall rules to allow required IP ranges](#firewall-rules-shared-vpc)\n2. [Grant permissions](#grant-permissions)\n3. [Create a subnet](#subnet)\n4. In the page [Configuring Serverless VPC Access](/vpc/docs/configure-serverless-vpc-access), complete the steps in the following sections:\n - [Create a Serverless VPC Access connector](/vpc/docs/configure-serverless-vpc-access#create-connector)\n - [Configure your serverless environment to use a connector](/vpc/docs/configure-serverless-vpc-access#configure-environment)\n\nAdd firewall rules to allow IP ranges\n-------------------------------------\n\nTo perform these steps, you must have one of the following roles on the\nhost project:\n\n- Compute Engine [Security Admin](/compute/docs/access/iam#compute.securityAdmin) role\n- Custom [Identity and Access Management (IAM)](/iam) role with the [`compute.firewalls.create`](/compute/docs/reference/rest/v1/firewalls/insert#iam-permissions) permission enabled\n\nYou must create firewall rules to allow requests from the following IP ranges to\nreach the connector and to be reached by the connector:\n\n- NAT ranges\n - `107.178.230.64/26`\n - `35.199.224.0/19`\n- Health check ranges\n - `130.211.0.0/22`\n - `35.191.0.0/16`\n - `108.170.220.0/23`\n\nThese ranges are used by the Google infrastructure underlying Cloud Run,\nCloud Run functions, and App Engine Standard. All requests from these IPs are guaranteed\nto originate from Google infrastructure, which ensures that your function\nonly communicates with the VPC connector it is connected to.\n\nFor a simple configuration, apply the rules to allow serverless services in any\nservice project connected to the Shared VPC network to send requests to\nany resource in the network.\n| **Important:** The rules you create using the following process apply to existing and future connectors. If you want to scope these rules so they only apply to specified connectors, see [Create firewall rules for specific connectors](#create_firewall_rules_for_specific_connectors).\n\nTo apply these rules:\n\n1. Run the following three commands to set the rules to allow requests from the\n serverless environment to reach all VPC Connectors in the network:\n\n **Note:** In these commands, UDP and TCP ports are used for proxying and HTTP health checks, respectively. \n\n ```bash\n gcloud compute firewall-rules create serverless-to-vpc-connector \\\n --allow tcp:667,udp:665-666,icmp \\\n --source-ranges 107.178.230.64/26,35.199.224.0/19 \\\n --direction=INGRESS \\\n --target-tags vpc-connector \\\n --network=VPC_NETWORK\n ``` \n\n ```bash\n gcloud compute firewall-rules create vpc-connector-to-serverless \\\n --allow tcp:667,udp:665-666,icmp \\\n --destination-ranges 107.178.230.64/26,35.199.224.0/19 \\\n --direction=EGRESS \\\n --target-tags vpc-connector \\\n --network=VPC_NETWORK\n ``` \n\n ```bash\n gcloud compute firewall-rules create vpc-connector-health-checks \\\n --allow tcp:667 \\\n --source-ranges 130.211.0.0/22,35.191.0.0/16,108.170.220.0/23 \\\n --direction=INGRESS \\\n --target-tags vpc-connector \\\n --network=VPC_NETWORK\n ```\n\n Where \u003cvar translate=\"no\"\u003eVPC_NETWORK\u003c/var\u003e is the VPC network to attach your\n connector to.\n2. Create an ingress rule on your VPC network to allow requests\n from connectors:\n\n ```bash\n gcloud compute firewall-rules create vpc-connector-requests \\\n --allow tcp,udp,icmp \\\n --direction=INGRESS \\\n --source-tags vpc-connector \\\n --network=VPC_NETWORK\n ```\n\n This rule gives the VPC connector access to every resource in the network. To\n limit the resources that your serverless environment can reach using\n Serverless VPC Access,\n [specify a target for these firewall rules](/vpc/docs/firewalls#rule_assignment).\n\n### Create firewall rules for specific connectors\n\nFollowing the procedure in\n[Add firewall rules to allow IP ranges](#firewall-rules-shared-vpc)\nresults in firewall rules that apply to *all* connectors, both current ones\nand ones created in the future. If you don't want this, but instead want to\ncreate rules for specific connectors only, you can scope the rules so that\nthey apply only to those connectors.\n\nTo limit the scope of the rules to specific connectors, you can use one of the\nfollowing mechanisms:\n\n- Network tags. Every connector has two network tags: `vpc-connector` and `vpc-connector-`\u003cvar translate=\"no\"\u003eREGION\u003c/var\u003e`-`\u003cvar translate=\"no\"\u003eCONNECTOR_NAME\u003c/var\u003e. Use the latter format to limit the scope of your firewall rules to a specific connector.\n- IP ranges. Use this for the Egress rules only, because it doesn't work for Ingress. You can use the IP range of the connector subnet to limit the scope of your firewall rules to a single VPC connector.\n\nGrant permissions to service accounts in your service projects\n--------------------------------------------------------------\n\nFor each service project that will use VPC Connectors, a Shared VPC\nAdmin must grant the Compute Network User\nrole ([`compute.networkUser`](/compute/docs/access/iam#compute.networkUser)) in the\nhost project to the service project `cloudservices` and `vpcaccess` service\naccounts.\n\nTo grant the role:\n\n1. Use these commands:\n\n ```bash\n gcloud projects add-iam-policy-binding HOST_PROJECT_ID \\\n --role \"roles/compute.networkUser\" \\\n --member \"serviceAccount:service-\u003cvar translate=\"no\"\u003eSERVICE_PROJECT_NUMBER\u003c/var\u003e@gcp-sa-vpcaccess.iam.gserviceaccount.com\"\n ``` \n\n ```bash\n gcloud projects add-iam-policy-binding HOST_PROJECT_ID \\\n --role \"roles/compute.networkUser\" \\\n --member \"serviceAccount:\u003cvar translate=\"no\"\u003eSERVICE_PROJECT_NUMBER\u003c/var\u003e@cloudservices.gserviceaccount.com\"\n ```\n2. If the `@gcp-sa-vpcaccess` service account does not exist, turn on the\n Serverless VPC Access API in the service project and try again:\n\n ```bash\n gcloud services enable vpcaccess.googleapis.com\n ```\n\n \u003cbr /\u003e\n\nIf you prefer not to grant these service accounts access to the entire\nShared VPC network and would rather only grant access to specific subnets, you\ncan instead [grant these roles to these service accounts on specific subnets only](/vpc/docs/shared-vpc#svc_proj_admins).\n\nCreate a subnet\n---------------\n\nWhen using Shared VPC, the Shared VPC Admin must create a subnet\nfor each connector. Follow the documentation in\n[adding a subnet](/vpc/docs/create-modify-vpc-networks#add-subnets) to add a `/28` subnet to the\nShared VPC network. This subnet must be in the same region as the\nserverless services that will use the connector.\n\nNext steps\n----------\n\n- In the page [Configuring Serverless VPC Access](/vpc/docs/configure-serverless-vpc-access), complete the steps in the following sections:\n - [Create a Serverless VPC Access connector](/vpc/docs/configure-serverless-vpc-access#create-connector)\n - [Configure your serverless environment to use a connector](/vpc/docs/configure-serverless-vpc-access#configure-environment)"]]
