The following sections describe quotas and limits for Cloud VPN. To change a quota, simply request additional quota using the Cloud Console. Limits cannot generally be increased unless specifically noted.
This table covers important quotas per project. See the Console quotas page for other quotas.
|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 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. See
Cloud Router quotas and limits for
Subject to the Cloud Router quotas and limits, the number of Cloud Routers is entirely independent of the type of Cloud VPN gateway, Classic VPN or HA VPN, that a tunnel is attached to, although 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|
The following limits apply to Cloud VPN. In this table, VPN tunnel means either a Classic VPN tunnel or a HA VPN tunnel. Unless otherwise stated, these limits cannot be increased.
|Bandwidth per VPN tunnel||Up to 3 Gbps for the sum of ingress and egress||This maximum bandwidth can only be achieved by using a
MTU size of 1,460
bytes and a packet rate of 250,000 packets per second (pps).
Cloud VPN only throttles egress IPsec traffic. It does not throttle ingress traffic.
Refer to Network bandwidth for more details.

for a working HA VPN connection.
Viewing Cloud Monitoring metrics for HA VPN
To view Monitoring metrics for HA VPN, you must use Metrics Explorer. See the Viewing logs and metrics page
Configuring VPN tunnels to AWS
When setting up VPN tunnels to AWS, using IKEv2 and configuring fewer IKE transform sets is required.
Cloud VPN enforces quotas on resource usage for a variety of 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 may increase automatically based on your use of a product.
To view quotas or request quota increases, Identity and Access Management (IAM) members need one of the following roles.
|Check quotas for a project||Project owner or editor or Quota Viewer|
|Modify quotas, request additional quota||Project

Checking your quota
- In the Cloud Console, go to the Quotas page.
- 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 command-line tool, 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 outputs a
quota exceeded error
message and returns with the exit code
If you exceed a quota with an API request, Google Cloud returns the
following HTTP status code:
HTTP 413 Request Entity Too Large.
Requesting additional quota
Request additional quota from the Quotas page in the Cloud Console. Quota requests take 24 to 48 hours to process.
- In the Cloud Console, go to the Quotas page.
- On the Quotas page, select the quotas that you want to change.
- At the top of the page, click Edit quotas.
- Fill out your name, email, and phone number, and then click Next.
- Fill in your quota request, and then click Done.
- Submit your request.
Each quota represents a maximum number for a particular type of resource that you can create, provided that resource is available. It's important to note that quotas do not guarantee resource availability. Even if you have available quota, you won't be able to 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, but that would
not be possible if there were 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.
