project STRING Required

Project ID for this request

region STRING Required

Name of the region scoping this request

filter STRING

A filter expression that filters resources listed in the response. The expression must specify the field name, a comparison operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The comparison 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.

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)

maxResults INTEGER

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)

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

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

id STRING

[Output Only] Unique identifier for the resource; defined by the server

items[] OBJECT

Represents a Forwarding Rule resource.

A forwardingRules resource represents a regional forwarding rule.

Regional external forwarding rules can reference any of the following resources:

• A target instance
• A Cloud VPN Classic gateway (targetVpnGateway),
• A target pool for a Network Load Balancer
• A global target HTTP(S) proxy for an HTTP(S) load balancer using Standard Tier
• A target SSL proxy for a SSL Proxy load balancer using Standard Tier
• A target TCP proxy for a TCP Proxy load balancer using Standard Tier.

Regional internal forwarding rules can reference the backend service of an internal TCP/UDP load balancer.

For regional internal forwarding rules, the following applies:

• If the loadBalancingScheme for the load balancer is INTERNAL, then the forwarding rule references a regional internal backend service.
• If the loadBalancingScheme for the load balancer is INTERNAL_MANAGED, then the forwarding rule must reference a regional target HTTP(S) proxy.

For more information, read Using Forwarding rules.

A globalForwardingRules resource represents a global forwarding rule.

Global forwarding rules are only used by load balancers that use Premium Tier. (== resource_for beta.forwardingRules ==) (== resource_for v1.forwardingRules ==) (== resource_for beta.globalForwardingRules ==) (== resource_for v1.globalForwardingRules ==) (== resource_for beta.regionForwardingRules ==) (== resource_for v1.regionForwardingRules ==)

items[].IPAddress STRING

The IP address that this forwarding rule is serving on behalf of.

Addresses are restricted based on the forwarding rule's load balancing scheme (EXTERNAL or INTERNAL) and scope (global or regional).

When the load balancing scheme is EXTERNAL, for global forwarding rules, the address must be a global IP, and for regional forwarding rules, the address must live in the same region as the forwarding rule. If this field is empty, an ephemeral IPv4 address from the same scope (global or regional) will be assigned. A regional forwarding rule supports IPv4 only. A global forwarding rule supports either IPv4 or IPv6.

When the load balancing scheme is INTERNAL_SELF_MANAGED, this must be a URL reference to an existing Address resource ( internal regional static IP address), with a purpose of GCE_END_POINT and address_type of INTERNAL.

When the load balancing scheme is INTERNAL, this can only be an RFC 1918 IP address belonging to the network/subnet configured for the forwarding rule. By default, if this field is empty, an ephemeral internal IP address will be automatically allocated from the IP range of the subnet or network configured for this forwarding rule.

An address can be specified either by a literal IP address or a URL reference to an existing Address resource. The following examples are all valid:

• 100.1.2.3
• https://www.googleapis.com/compute/v1/projects/project/regions/region/addresses/address
• projects/project/regions/region/addresses/address
• regions/region/addresses/address
• global/addresses/address
• address

items[].IPProtocol ENUMERATION
