New – Direct VPC Routing Between On-Premises Networks and AWS Outposts Rack
https://aws.amazon.com/polly/ Today, we announced direct VPC routing for https://aws.amazon.com/outposts/rack/. Direct VPC routing automatically advertises https://aws.amazon.com/vpc/ subnet CIDR addresses to on-premises networks.
Previously, to configure network routing between an on-premises network and an Outposts rack, you needed to use Customer-owned IP addresses (CoIP).
When an https://aws.amazon.com/ec2/ instance on your Outposts rack needed to communicate with your on-premises network, Outposts rack would perform a 1:1 network address translation (NAT) from the VPC private IP address to a CoIP address in the CoIP pool.
Enabling Direct VPC Routing You can select either CoIP or direct VPC routing approaches and utilize a new https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_LocalGatewayRouteTable.html, CreateLocalGatewayRouteTable, to configure direct VPC routing for both new and existing Outposts racks.
