Container traffic routing can be enabled by setting and NAT outgoing on the configured Calico IP pools.

Traffic routing in GCE can be achieved by utilizing GCE cloud routes and running Calico in policy-only mode. Kubernetes GCE cloud provider integration simplifies route configuration by enabling Kubernetes to handle creating routes.

GCE will perform outbound NAT on any traffic which has the source address of a virtual machine instance. By enabling outgoing NAT on your Calico IP pool, Calico will NAT any outbound traffic from the containers hosted on the virtual machine instances.
