Overview

Represents a Forwarding Rule resource.

Forwarding rule resources in Google Cloud can be either regional or global in scope:

• Global
• Regional

A forwarding rule and its corresponding IP address represent the frontend configuration of a Google Cloud load balancer. Forwarding rules can also reference target instances and Cloud VPN Classic gateways (targetVpnGateway).

For more information, read Forwarding rule concepts and Using protocol forwarding.

Instance Attribute Details

#all_ports ⇒ ::Boolean

Returns The ports, portRange, and allPorts fields are mutually exclusive. Only packets addressed to ports in the specified range will be forwarded to the backends configured with this forwarding rule.

The allPorts field has the following limitations:

• It requires that the forwarding rule IPProtocol be TCP, UDP, SCTP, or L3_DEFAULT.
• It's applicable only to the following products: internal passthrough Network Load Balancers, backend service-based external passthrough Network Load Balancers, and internal and external protocol forwarding.
• Set this field to true to allow packets addressed to any port or packets lacking destination port information (for example, UDP fragments after the first fragment) to be forwarded to the backends configured with this forwarding rule. The L3_DEFAULT protocol requiresallPorts be set to true.

Returns:

• (::Boolean) —

#I_p_address ⇒ ::String

Returns 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 andvalidateForProxyless is set to true, theIPAddress 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 inhttps://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.

When reading an IPAddress, the API always returns the IP address number.

Otherwise, all the resources (e.g.TargetHttpProxy, UrlMap) referenced by the ForwardingRule are not visible to those proxies.

For each metadataFilter in this list, if itsfilterMatchCriteria is set to MATCH_ANY, at least one of thefilterLabels must match the corresponding label provided in the metadata. If its filterMatchCriteria is set to MATCH_ALL, then all of its filterLabels must match with corresponding labels provided in the metadata. If multiplemetadataFilters are specified, all of them need to be satisfied in order to be considered a match.

metadataFilters specified here will be applifed before those specified in the UrlMap that thisForwardingRule references.

metadataFilters only applies to Loadbalancers that have their loadBalancingScheme set toINTERNAL_SELF_MANAGED.

#target ⇒ ::String

Returns 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. The target is not mutable once set as a service attachment.

Returns:
