     *     @type string[]|\Google\Protobuf\Internal\RepeatedField $ports
     *           The ports field is only supported when the forwarding rule references a backend_service directly. Supported load balancing products are Internal TCP/UDP Load Balancing and Network Load Balancing. Only packets addressed to the specified list of ports are forwarded to backends.
     *           You can only use one of ports and port_range, or allPorts. The three are mutually exclusive.
     *           You can specify a list of up to five ports, which can be non-contiguous.
     *           For Internal TCP/UDP Load Balancing, if you specify allPorts, you should not specify ports.
     *           For more information, see [Port specifications](https://cloud.google.com/load-balancing/docs/forwarding-rule-concepts#port_specifications).
     *     @type string $region
     *           [Output Only] URL of the region where the regional forwarding rule resides. This field is not applicable to global forwarding rules. You must specify this field as part of the HTTP request URL. It is not settable as a field in the request body.
     *     @type string $self_link
     *           [Output Only] Server-defined URL for the resource.
     *     @type string $service_label
     *           An optional prefix to the service name for this Forwarding Rule. If specified, the prefix is the first label of the fully qualified service name.
     *           The label must be 1-63 characters long, and comply with RFC1035. Specifically, the label must be 1-63 characters long and match the regular expression `[a-z]([-a-z0-9]*[a-z0-9])?` which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash.
     *           This field is only used for internal load balancing.
     *     @type string $service_name
     *           [Output Only] The internal fully qualified service name for this Forwarding Rule.
     *           This field is only used for internal load balancing.
     *     @type string $subnetwork
     *           This field is only used for internal load balancing.
     *           For internal load balancing, this field identifies the subnetwork that the load balanced IP should belong to for this Forwarding Rule.
     *           If the network specified is in auto subnet mode, this field is optional. However, if the network is in custom subnet mode, a subnetwork must be specified.
     *     @type string $target
     *           The URL of the target resource to receive the matched traffic. For regional forwarding rules, this target must be in the same region as the forwarding rule. For global forwarding rules, this target must be a global load balancing resource. The forwarded traffic must be of a type appropriate to the target object. For more information, see the "Target" column in [Port specifications](https://cloud.google.com/load-balancing/docs/forwarding-rule-concepts#ip_address_specifications).
     *           For Private Service Connect forwarding rules that forward traffic to Google APIs, provide the name of a supported Google API bundle. Currently, the supported Google API bundles include:
     *           - vpc-sc - GCP APIs that support VPC Service Controls. For more information about which APIs support VPC Service Controls, refer to VPC-SC supported products and limitations.
     *           - all-apis - All GCP APIs. For more information about which APIs are supported with this bundle, refer to Private Google Access-specific domains and VIPs.
