Properties

AllPorts

public bool AllPorts { get; set; }

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 requires allPorts be set to true.

Property Value
Type Description
bool

AllowGlobalAccess

public bool AllowGlobalAccess { get; set; }

If set to true, clients can access the internal passthrough Network Load Balancers, the regional internal Application Load Balancer, and the regional internal proxy Network Load Balancer from all regions. If false, only allows access from the local region the load balancer is located at. Note that for INTERNAL_MANAGED forwarding rules, this field cannot be changed after the forwarding rule is created.

IPAddress

public string IPAddress { get; set; }

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

Property Value
Type Description

LabelFingerprint

public string LabelFingerprint { get; set; }

A fingerprint for the labels being applied to this resource, which is essentially a hash of the labels set used for optimistic locking. The fingerprint is initially generated by Compute Engine and changes after every request to modify or update labels. You must always provide an up-to-date fingerprint hash in order to update or change labels, otherwise the request will fail with error 412 conditionNotMet. To see the latest fingerprint, make a get() request to retrieve a ForwardingRule.

Property Value

MetadataFilters

public RepeatedField<MetadataFilter> MetadataFilters { get; }

Opaque filter criteria used by load balancer to restrict routing configuration to a limited set of xDS compliant clients. In their xDS requests to load balancer, xDS clients present node metadata. When there is a match, the relevant configuration is made available to those proxies. 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 its filterMatchCriteria is set to MATCH_ANY, at least one of the filterLabels 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 multiple metadataFilters 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 this ForwardingRule references. metadataFilters only applies to Loadbalancers that have their loadBalancingScheme set to INTERNAL_SELF_MANAGED.

Property Value
Type Description
RepeatedFieldMetadataFilter

For Private Service Connect forwarding rules that forward traffic to Google APIs, a network must be provided.

Property Value
Type Description
string

NetworkTier

public string NetworkTier { get; set; }

This signifies the networking tier used for configuring this load balancer and can only take the following values: PREMIUM, STANDARD. For regional ForwardingRule, the valid values are PREMIUM and STANDARD. For GlobalForwardingRule, the valid value is PREMIUM. If this field is not specified, it is assumed to be PREMIUM.
