Subnet compatibility for Resolver endpoints

We recommend using VPC Resolver on AWS Outposts to create endpoints on AWS Outposts Racks.

Important

Outposts subnets with Local Network Interface (LNI) enabled are not compatible with VPC Resolver endpoints. If you enable LNI on a subnet that contains VPC Resolver endpoint elastic network interfaces (ENIs), those ENIs will stop functioning.

To avoid this issue:

  • Before creating a Resolver endpoint, verify that the target subnets don't have LNI enabled.

  • Don't enable LNI on subnets that already contain Resolver endpoint ENIs.

  • If you need both LNI and Resolver endpoints, use separate subnets for each.

For more information about LNI, see Local network interfaces in the AWS Outposts User Guide.
