allPorts

This field can be used with internal load balancer or network load balancer when the forwarding rule references a backend service, or with the target field when it references a TargetInstance. Set this to true to allow packets addressed to any ports to be forwarded to the backends configured with this forwarding rule. This can be used when the protocol is TCP/UDP, and it must be set to true when the protocol is set to L3_DEFAULT. Cannot be set if port or portRange are set.
