Access an inspection system using a Gateway Load Balancer endpoint

You can create a Gateway Load Balancer endpoint to connect to endpoint services powered by Amazon PrivateLink.

For each subnet that you specify from your VPC, we create an endpoint network interface in the subnet and assign it a private IP address from the subnet address range. An endpoint network interface is a requester-managed network interface; you can view it in your Amazon Web Services account, but you can't manage it yourself.

Considerations

  • You can choose only one Availability Zone in the service consumer VPC. You can't change this subnet later on. To use a Gateway Load Balancer endpoint in a different subnet, you must create a new Gateway Load Balancer endpoint.

  • You can create a single Gateway Load Balancer endpoint per Availability Zone per service, and you must select the Availability Zone that the Gateway Load Balancer supports. When the service provider and service consumer are in different accounts, an Availability Zone name, such as us-east-1a, might be mapped to a different physical Availability Zone in each Amazon Web Services account. You can use AZ IDs to consistently identify the Availability Zones for your service. For more information, see AZ IDs in the Amazon EC2 User Guide for Linux Instances.

  • Before you can use the endpoint service the service provider must accept the connection requests. The service can't initiate requests to resources in your VPC through the VPC endpoint. The endpoint only returns responses to traffic that was initiated by resources in your VPC.

  • Each Gateway Load Balancer endpoint can support a bandwidth of up to 10 Gbps per Availability Zone and automatically scales up to 100 Gbps.

  • If an endpoint service is associated with multiple Gateway Load Balancers, a Gateway Load Balancer endpoint establishes a connection with only one load balancer per Availability Zone.

  • To keep traffic within the same Availability Zone, we recommend that you create a Gateway Load Balancer endpoint in each Availability Zone to which you'll send traffic.

  • Network Load Balancer client IP preservation is not supported when traffic is routed through a Gateway Load Balancer endpoint, even if the target is in the same VPC as the Network Load Balancer.

  • There are quotas on your Amazon PrivateLink resources. For more information, see Amazon PrivateLink quotas.

Prerequisites

  • Create a service consumer VPC with at least two subnets in the Availability Zone from which you'll access the service. One subnet is for the application servers and the other is for the Gateway Load Balancer endpoint.

  • To verify which Availability Zones are supported by the endpoint service, describe the endpoint service using the console or the describe-vpc-endpoint-services command.

  • If your resources are in a subnet with a network ACL, verify that the network ACL allows traffic between the endpoint network interfaces and the resources in the VPC.

Create the endpoint

Use the following procedure to create a Gateway Load Balancer endpoint that connects to the endpoint service for the inspection system.

To create a Gateway Load Balancer endpoint using the console

  1. Open the Amazon VPC console at https://console.amazonaws.cn/vpc/.

  2. In the navigation pane, choose Endpoints.

  3. Choose Create endpoint.

  4. For Service category, choose Other endpoint services.

  5. For Service name, enter the name of the service, and then choose Verify service.

  6. For VPC, select the VPC in which to create the endpoint.

  7. For Subnets, select the subnet in which to create the endpoint.

  8. For IP address type, choose from the following options:

    • IPv4 – Assign IPv4 addresses to your endpoint network interfaces. This option is supported only if all selected subnets have IPv4 address ranges.

    • IPv6 – Assign IPv6 addresses to your endpoint network interfaces. This option is supported only if all selected subnets are IPv6 only subnets.

    • Dualstack – Assign both IPv4 and IPv6 addresses to your endpoint network interfaces. This option is supported only if all selected subnets have both IPv4 and IPv6 address ranges.

  9. (Optional) To add a tag, choose Add new tag and enter the tag key and the tag value.

  10. Choose Create endpoint. The initial status is pending acceptance.

Configure routing

Use the following procedure to configure route tables for the service consumer VPC. This enables the security appliances to perform security inspection for inbound traffic that's destined for the application servers. For more information, see Routing.

To configure routing using the console

  1. Open the Amazon VPC console at https://console.amazonaws.cn/vpc/.

  2. In the navigation pane, choose Route Tables.

  3. Select the route table for the internet gateway and do the following:

    1. Choose Actions, Edit routes.

    2. If you support IPv4, choose Add route. For Destination, enter the IPv4 CIDR block of the subnet for the application servers. For Target, select the VPC endpoint.

    3. If you support IPv6, choose Add route. For Destination, enter the IPv6 CIDR block of the subnet for the application servers. For Target, select the VPC endpoint.

    4. Choose Save changes.

  4. Select the route table for the subnet with the application servers and do the following:

    1. Choose Actions, Edit routes.

    2. If you support IPv4, choose Add route. For Destination, enter 0.0.0.0/0. For Target, select the VPC endpoint.

    3. If you support IPv6, choose Add route. For Destination, enter ::/0. For Target, select the VPC endpoint.

    4. Choose Save changes.

  5. Select the route table for the subnet with the Gateway Load Balancer endpoint, and do the following:

    1. Choose Actions, Edit routes.

    2. If you support IPv4, choose Add route. For Destination, enter 0.0.0.0/0. For Target, select the internet gateway.

    3. If you support IPv6, choose Add route. For Destination, enter ::/0. For Target, select the internet gateway.

    4. Choose Save changes.

Manage tags

You can tag your Gateway Load Balancer endpoint to help you identify it or categorize it according to your organization's needs.

To manage tags using the console

  1. Open the Amazon VPC console at https://console.amazonaws.cn/vpc/.

  2. In the navigation pane, choose Endpoints.

  3. Select the interface endpoint.

  4. Choose Actions, Manage tags.

  5. For each tag to add choose Add new tag and enter the tag key and tag value.

  6. To remove a tag, choose Remove to the right of the tag key and value.

  7. Choose Save.

To manage tags using the command line

Delete a Gateway Load Balancer endpoint

When you are finished with an endpoint, you can delete it. Deleting a Gateway Load Balancer endpoint also deletes the endpoint network interfaces. You can't delete a Gateway Load Balancer endpoint if there are routes in your route tables that point to the endpoint.

To delete a Gateway Load Balancer endpoint

  1. Open the Amazon VPC console at https://console.amazonaws.cn/vpc/.

  2. In the navigation pane, choose Endpoints and select your endpoint.

  3. Choose Actions, Delete Endpoint.

  4. In the confirmation screen, choose Yes, Delete.
