AWS Client VPN quotas

Your AWS account has the following quotas related to Client VPN endpoints.

Client VPN quotas

The following quotas apply to Client VPN. Unless indicated otherwise, you can request an increase for these quotas.

• Number of Client VPN endpoints per Region: 5

• Number of authorization rules per Client VPN endpoint: 50

• Number of routes per Client VPN endpoint: 10

• Number of concurrent client connections per Client VPN endpoint: 20,000

• Number of entries in a client certificate revocation list: 20,000

  This quota cannot be increased.

• Number of concurrent operations per Client VPN endpoint: 10

  Operations include:

  • Associating or disassociating subnets

  • Creating or deleting routes

  • Creating or deleting inbound and outbound rules

  • Creating or deleting security groups

  This quota cannot be increased.

Users and groups quotas

When you configure users and groups for Active Directory or a SAML-based IdP, the following quotas apply:

• Users can belong to a maximum of 200 groups. We ignore any groups after the 200th group.

• The maximum length for the group ID is 255 characters.

• The maximum length for the name ID is 255 characters. We truncate characters after the 255th character.

General considerations

Take the following into consideration when you use Client VPN endpoints:

• If you use Active Directory to authenticate the user, the Client VPN endpoint must belong to the same account as the AWS Directory Service resource used for Active Directory authentication.

• If you use SAML-based federated authentication to authenticate a user, the Client VPN endpoint must belong to the same account as the IAM SAML identity provider that you create to define the IdP-to-AWS trust relationship. The IAM SAML identity provider can be shared across multiple Client VPN endpoints in the same AWS account.
