Quotas and limits

This document lists the quotas and system limits that apply to Cloud VPN. Quotas specify the amount of a countable, shared resource that you can use, and they are defined by Google Cloud services such as Cloud VPN. System limits are fixed values that cannot be changed.

To change a quota, see requesting additional quota.

Google Cloud uses quotas to help ensure fairness and reduce spikes in resource use and availability. A quota restricts how much of a Google Cloud resource your Google Cloud project can use. Quotas apply to a range of resource types, including hardware, software, and network components. For example, quotas can restrict the number of API calls to a service, the number of load balancers used concurrently by your project, or the number of projects that you can create. Quotas protect the community of Google Cloud users by preventing the overloading of services. Quotas also help you to manage your own Google Cloud resources.

The Cloud Quotas system does the following:

Monitors your consumption of Google Cloud products and services
Restricts your consumption of those resources
Provides a way to request changes to the quota value

In most cases, when you attempt to consume more of a resource than its quota allows, the system blocks access to the resource, and the task that you're trying to perform fails.

Quotas generally apply at the Google Cloud project level. Your use of a resource in one project doesn't affect your available quota in another project. Within a Google Cloud project, quotas are shared across all applications and IP addresses.

There are also system limits on Cloud VPN resources. System limits can't be changed.

Quotas

This table covers important quotas per project. For other quotas, see the Google Cloud console Quotas page.

Item	Quota	Notes
VPN gateways	Quota	For HA VPN only
External VPN gateways	Quota	For HA VPN only
VPN tunnels	Quota	This quota represents the combined total number of Classic VPN tunnels and HA VPN tunnels.
Routers	Quota	This quota represents the number of Cloud Routers that you can create within your project, in any network and region. Networks also have a limit on the number of Cloud Routers in any given region. For more details, see Cloud Router quotas and limits. Subject to the Cloud Router quotas and limits, the number of Cloud Routers is independent of the type of Cloud VPN gateway, Classic VPN or HA VPN, that a tunnel is attached to. The quota is applied the same to either type of gateway.
Target VPN gateways	Quota	For Classic VPN only
Forwarding rules	Quota	For Classic VPN only

Limits

The following limits apply to Cloud VPN. In this table, VPN tunnel means either a Classic VPN tunnel or an HA VPN tunnel. Unless otherwise stated, these limits cannot be increased.

Item	Limit	Notes
Bandwidth per VPN tunnel	250,000 packets per second for the sum of ingress and egress	250,000 packets per second is roughly equivalent to 1 Gbps to 3 Gbps, depending on the average packet size within the tunnel. Cloud VPN only throttles egress IPsec traffic. It does not throttle ingress traffic. For more details, see Network bandwidth.

250,000 packets per second for the sum of ingress and egress

250,000 packets per second is roughly equivalent to 1 Gbps to 3 Gbps, depending on the average packet size within the tunnel.

Cloud VPN only throttles egress IPsec traffic. It does not throttle ingress traffic.

Known issues

Be aware of the following issues:

Google Cloud resources specific to HA VPN are not yet displayed in Cloud Asset Inventory or Security Command Center. These resources include compute.vpnGateways and compute.externalVpnGateways. However, the compute.vpnTunnels resource is listed in both locations and is required for a working HA VPN connection.
To view Cloud Monitoring metrics for HA VPN, use Metrics Explorer. For more information, see Viewing logs and metrics.
When setting up VPN tunnels to AWS, use IKEv2 and configure fewer IKE transform sets.

Manage quotas

Cloud VPN enforces quotas on resource usage for various reasons. For example, quotas protect the community of Google Cloud users by preventing unforeseen spikes in usage. Quotas also help users who are exploring Google Cloud with the free tier to stay within their trial.

All projects start with the same quotas, which you can change by requesting additional quota. Some quotas might increase automatically based on your use of a product.

Permissions

To view quotas or request quota increases, Identity and Access Management (IAM) principals need one of the following roles.

Task	Required role
Check quotas for a project	One of the following: Project Owner (`roles/owner`) Project Editor (`roles/editor`) Quota Viewer (`roles/servicemanagement.quotaViewer`)
Modify quotas, request additional quota	One of the following: Project Owner (`roles/owner`) Project Editor (`roles/editor`) Quota Administrator (`roles/servicemanagement.quotaAdmin`) A custom role with the `serviceusage.quotas.update` permission

Check your quota

Console

In the Google Cloud console, go to the Quotas page.
Go to Quotas
To search for the quota that you want to update, use the Filter table. If you don't know the name of the quota, use the links on this page instead.

gcloud

Using the Google Cloud CLI, run the following command to check your quotas. Replace PROJECT_ID with your own project ID.

    gcloud compute project-info describe --project PROJECT_ID

To check your used quota in a region, run the following command:

    gcloud compute regions describe example-region

Errors when exceeding your quota

If you exceed a quota with a gcloud command, gcloud outputs a quota exceeded error message and returns with the exit code 1.

If you exceed a quota with an API request, Google Cloud returns the following HTTP status code: 413 Request Entity Too Large.

Request additional quota

To adjust most quotas, use the Google Cloud console. For more information, see Request a quota adjustment.

Console

In the Google Cloud console, go to the Quotas page.
Go to Quotas
On the Quotas page, select the quotas that you want to change.
At the top of the page, click Edit quotas.
For Name, enter your name.
Optional: For Phone, enter a phone number.
Submit your request. Quota requests take 24 to 48 hours to process.

Resource availability

Each quota represents a maximum number for a particular type of resource that you can create, if that resource is available. It's important to note that quotas don't guarantee resource availability. Even if you have available quota, you can't create a new resource if it is not available.

For example, you might have sufficient quota to create a new regional, external IP address in the us-central1 region. However, that is not possible if there are no available external IP addresses in that region. Zonal resource availability can also affect your ability to create a new resource.

Situations where resources are unavailable in an entire region are rare. However, resources within a zone can be depleted from time to time, typically without impact to the service level agreement (SLA) for the type of resource. For more information, review the relevant SLA for the resource.
