HTTP request


GET https://compute.googleapis.com/compute/v1/projects/{project}/global/forwardingRules?$apiVersion=2026-09-01

The URLs use gRPC Transcoding syntax.

Path parameters

Parameters
project

string

Project ID for this request.

Query parameters

Parameters
maxResults

integer (uint32 format)

The maximum number of results per page that should be returned. If the number of available results is larger than maxResults, Compute Engine returns a nextPageToken that can be used to get the next page of results in subsequent list requests. Acceptable values are 0 to 500, inclusive. (Default: 500)
pageToken

string

Specifies a page token to use. Set pageToken to the nextPageToken returned by a previous list request to get the next page of results.
filter

string

A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request.

If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either =, !=, >, <, <=, >= or :.

For example, if you are filtering Compute Engine instances, you can exclude instances named example-instance by specifying name != example-instance.

The :* comparison can be used to test whether a key has been defined. For example, to find all objects with owner label use:

labels.owner:*

You can also filter nested fields. For example, you could specify scheduling.automaticRestart = false to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels.

To filter on multiple expressions, provide each separate expression within parentheses. For example:

(scheduling.automaticRestart = true)
(cpuPlatform = "Intel Skylake")

By default, each expression is an AND expression. However, you can include AND and OR expressions explicitly. For example:

(cpuPlatform = "Intel Skylake") OR
(cpuPlatform = "Intel Broadwell") AND
(scheduling.automaticRestart = true)

If you want to use a regular expression, use the eq (equal) or ne (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples:

fieldname eq unquoted literal fieldname eq 'single quoted literal' fieldname eq "double quoted literal" (fieldname1 eq literal) (fieldname2 ne "literal")

The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field.

For example, to filter for instances that do not end with name "instance", you would use name ne .*instance.

You cannot combine constraints on multiple fields using regular expressions.
orderBy

string

Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name.

You can also sort results in descending order based on the creation timestamp using orderBy="creationTimestamp desc". This sorts results based on the creationTimestamp field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first.

Currently, only sorting by name or creationTimestamp desc is supported.

Request body

The request body must be empty.

Fields
kind

string

Output only. Type of resource.
id

string

Output only. Unique identifier for the resource; defined by the server.
items[]

object

A list of ForwardingRule resources.
items[].kind

string

Output only. Type of the resource. Always compute#forwardingRule for forwarding rule resources.
items[].id

string (uint64 format)

Output only. The unique identifier for the resource. This identifier is defined by the server.
items[].creationTimestamp

string

Output only. Creation timestamp in RFC3339 text format.
items[].name

string

Name of the resource; provided by the client when the resource is created. The name must be 1-63 characters long, and comply with RFC1035. Specifically, the name 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.

For Private Service Connect forwarding rules that forward traffic to Google APIs, the forwarding rule name must be a 1-20 characters string with lowercase letters and numbers and must start with a letter.

For global external Passthrough Network Load Balancer forwarding rules, the forwarding rule name must be 1-43 characters long. For each global external Passthrough Network Load Balancer forwarding rule (a parent forwarding rule) that you create, Google Cloud generates two output-only child forwarding rules that are named by concatenating the parent forwarding rule name with the -ag0 and -ag1 suffixes, respectively. Refer to the availabilityGroup field for further details.
items[].description

string

An optional description of this resource. Provide this property when you create the resource.
items[].region

string

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.
items[].IPAddress

string

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:

The IP address can only be set at creation. Once set, it cannot be updated.

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.

When creating a global external Passthrough Network Load Balancer forwarding rule (a parent forwarding rule), you must use the IPAddresses field, but the Google Cloud generated child forwarding rules set the IPAddress field instead. Refer to the availabilityGroup field for further details.
items[].IPProtocol

enum

The IP protocol to which this rule applies.

For protocol forwarding, valid options are TCP, UDP, ESP, AH, SCTP, ICMP and L3_DEFAULT.

The valid IP protocols are different for different load balancing products as described in Load balancing features.
items[].portRange

string

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 portRange field has the following limitations:

  • It requires that the forwarding rule IPProtocol be TCP, UDP, or SCTP, and
  • It's applicable only to the following products: external passthrough Network Load Balancers, internal and external proxy Network Load Balancers, internal and external Application Load Balancers, external protocol forwarding, and Classic VPN.
  • Some products have restrictions on what ports can be used. See port specifications for details.

For external forwarding rules, two or more forwarding rules cannot use the same [IPAddress, IPProtocol] pair (specified in IPAddress, IPAddresses, IPProtocol fields) if they have overlapping portRanges.

For internal forwarding rules within the same VPC network, two or more forwarding rules cannot use the same [IPAddress, IPProtocol] pair, and cannot have overlapping portRanges.

@pattern: \d+(?:-\d+)?
items[].ports[]

string

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 ports field has the following limitations:

  • It requires that the forwarding rule IPProtocol be TCP, UDP, or SCTP, and
  • It's applicable only to the following products: internal passthrough Network Load Balancers, backend service-based external passthrough Network Load Balancers, and internal protocol forwarding.
  • You can specify a list of up to five ports by number, separated by commas. The ports can be contiguous or discontiguous.

For external forwarding rules, two or more forwarding rules cannot use the same [IPAddress, IPProtocol] pair (specified in IPAddress, IPAddresses, IPProtocol fields) if they share at least one port number.

For internal forwarding rules within the same VPC network, two or more forwarding rules cannot use the same [IPAddress, IPProtocol] pair if they share at least one port number.

@pattern: \d+(?:-\d+)?
items[].target

string

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.
  • For Private Service Connect forwarding rules that forward traffic to Google APIs, provide the name of a supported Google API bundle:
  • 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.

The following load balancers cannot set the target field (they should set the backendService field instead):

  • Internal passthrough Network Load Balancers
  • Backend service-based regional external passthrough Network Load Balancers
  • G
