This blueprint creates a networking playground showing a number of different VPC connectivity options: Hub and spoke via HA VPN Hub and spoke via VPC peering Interconnecting two networks via a network virtual appliance (aka NVA) On top of that, this blueprint implements Policy Based Routing (aka PBR) to show how to force all traffic within a VPC to be funneled through an internal network passthrough load balancer, to implement an Intrusion Prevention System (IPS). PBR is enabled in the hub VPC, matching all traffic originating from within that VPC.
