     * IP address for which this forwarding rule accepts traffic. When a client sends traffic to this IP address, the forwarding rule directs the traffic to the referenced target or backendService. While creating a forwarding rule, specifying an IPAddress is required under the following circumstances: - When the target is set to targetGrpcProxy and validateForProxyless is set to true, the IPAddress should be set to 0.0.0.0. - When the target is a Private Service Connect Google APIs bundle, you must specify an IPAddress. Otherwise, you can optionally specify an IP address that references an existing static (reserved) IP address resource. When omitted, Google Cloud assigns an ephemeral IP address. Use one of the following formats to specify an IP address while creating a forwarding rule: * IP address number, as in `100.1.2.3` * IPv6 address range, as in `2600:1234::/96` * Full resource URL, as in https://www.googleapis.com/compute/v1/projects/ project_id/regions/region/addresses/address-name * Partial URL or by name, as in: - projects/project_id/regions/region/addresses/address-name - regions/region/addresses/address-name - global/addresses/address-name - address-name The forwarding rule's target or backendService, and in most cases, also the loadBalancingScheme, determine the type of IP address that you can use. For detailed information, see [IP address specifications](https://cloud.google.com/load-balancing/docs/forwarding-rule-concepts#ip_address_specifications).

     *     @type int|string $psc_connection_id

     *           
     *           Check the PscConnectionStatus enum for the list of possible values.
     *     @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 array<\Google\Cloud\Compute\V1\ForwardingRuleServiceDirectoryRegistration>|\Google\Protobuf\Internal\RepeatedField $service_directory_registrations
     *           Service Directory resources to register this forwarding rule with. Currently, only supports a single Service Directory 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 identifies the subnetwork that the load balanced IP should belong to for this Forwarding Rule, used in internal load balancing and network load balancing with IPv6. If the network specified is in auto subnet mode, this field is optional. However, a subnetwork must be specified if the network is in custom subnet mode or when creating external forwarding rule with IPv6.
     *     @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 load balancers, 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: - vpc-sc - APIs that support VPC Service Controls. - all-apis - All supported Google APIs. - For Private Service Connect forwarding rules that forward traffic to managed services, the target must be a service attachment.
