Forwarding rules can be either global or regional, specified with the --global or --region=REGION flags. For more information about the scope of a forwarding rule, refer to https://cloud.google.com/load-balancing/docs/forwarding-rule-concepts.

Forwarding rules can be external, internal, internal managed, or internal self-managed, specified with the --load-balancing-scheme=[EXTERNAL|EXTERNAL_MANAGED|INTERNAL|INTERNAL_MANAGED|INTERNAL_SELF_MANAGED] flag. External forwarding rules are accessible from the internet, while internal forwarding rules are only accessible from within their VPC networks. You can specify a reserved static external or internal IP address with the --address=ADDRESS flag for the forwarding rule. Otherwise, if the flag is unspecified, an ephemeral IP address is automatically assigned (global IP addresses for global forwarding rules and regional IP addresses for regional forwarding rules); an internal forwarding rule is automatically assigned an ephemeral internal IP address from the subnet specified with the --subnet flag. You must provide an IP address for an internal self-managed forwarding rule.

Different types of load balancers work at different layers of the OSI networking model (http://en.wikipedia.org/wiki/Network_layer). Layer 3/4 targets include target pools, target SSL proxies, target TCP proxies, and backend services. Layer 7 targets include target HTTP proxies and target HTTPS proxies. For more information, refer to https://cloud.google.com/load-balancing/docs/forwarding-rule-concepts. When creating a forwarding rule, exactly one of --target-instance, --target-pool, --target-http-proxy, --target-https-proxy, --target-grpc-proxy, --target-ssl-proxy, --target-tcp-proxy, --target-vpn-gateway, --backend-service or --target-google-apis-bundle must be specified.

gcloud alpha compute forwarding-rules create RULE_NAME --global --target-http-proxy=PROXY --ports=8080 --address=ADDRESS

To create a regional forwarding rule for the subnet SUBNET_NAME on the default network that will forward all traffic on ports 80-82 to a backend service SERVICE_NAME, run:

gcloud alpha compute forwarding-rules create RULE_NAME --load-balancing-scheme=INTERNAL --backend-service=SERVICE_NAME --subnet=SUBNET_NAME --network=default --region=REGION --ports=80-82

NAME

Name of the forwarding rule to create.

Exactly one of these must be specified:

--backend-service=BACKEND_SERVICE

Target backend service that receives the traffic.

--target-google-apis-bundle=TARGET_GOOGLE_APIS_BUNDLE

Target bundle of Google APIs that will receive forwarded traffic via Private Service Connect. Acceptable values are all-apis, meaning all Google APIs, or vpc-sc, meaning just the APIs that support VPC Service Controls

--target-grpc-proxy=TARGET_GRPC_PROXY

Target gRPC proxy that receives the traffic.

--target-http-proxy=TARGET_HTTP_PROXY

Target HTTP proxy that receives the traffic. For the acceptable ports, see Port specifications.

--target-https-proxy=TARGET_HTTPS_PROXY

Target HTTPS proxy that receives the traffic. For the acceptable ports, see Port specifications.

--target-instance=TARGET_INSTANCE

Name of the target instance that receives the traffic. The target instance must be in a zone in the forwarding rule's region. Global forwarding rules cannot direct traffic to target instances. If not specified and the compute/zone property isn't set, you might be prompted to select a zone (interactive mode only).

To avoid prompting when this flag is omitted, you can set the compute/zone property:

gcloud config set compute/zone ZONE

A list of zones can be fetched by running:

gcloud compute zones list

To unset the property, run:

gcloud config unset compute/zone

Alternatively, the zone can be stored in the environment variable CLOUDSDK_COMPUTE_ZONE.

--target-pool=TARGET_POOL

Target pool that receives the traffic. The target pool must be in the same region as the forwarding rule. Global forwarding rules cannot direct traffic to target pools.

--target-service-attachment=TARGET_SERVICE_ATTACHMENT

Target service attachment that receives the traffic. The target service attachment must be in the same region as the forwarding rule.

--target-ssl-proxy=TARGET_SSL_PROXY

Target SSL proxy that receives the traffic. For the acceptable ports, see Port specifications.

--target-tcp-proxy=TARGET_TCP_PROXY

Target TCP proxy that receives the traffic. For the acceptable ports, see Port specifications.

--target-vpn-gateway=TARGET_VPN_GATEWAY

Target VPN gateway (Cloud VPN Classic gateway) that receives forwarded traffic. Acceptable values for --ports flag are: 500, 4500.

--address=ADDRESS

The IP address that the forwarding rule serves. When a client sends traffic to this IP address, the forwarding rule directs the traffic to the target that you specify in the forwarding rule.

If you don't specify a reserved IP address, an ephemeral IP address is assigned. You can specify the IP address as a literal IP address or as a reference to an existing Address resource. The following examples are all valid:

• 100.1.2.3
• 2600:1901::/96
• https://compute.googleapis.com/compute/v1/projects/project-1/regions/us-central1/addresses/address-1
• projects/project-1/regions/us-central1/addresses/address-1
• regions/us-central1/addresses/address-1
• global/addresses/address-1
• address-1

The load-balancing-scheme (EXTERNAL, EXTERNAL_MANAGED, INTERNAL, INTERNAL_SELF_MANAGED, INTERNAL_MANAGED) and the target of the forwarding rule determine the type of IP address that you can use. The address type must be external for load-balancing-scheme EXTERNAL or EXTERNAL_MANAGED. For other load-balancing-schemes, the address type must be internal. For detailed information, refer to https://cloud.google.com/load-balancing/docs/forwarding-rule-concepts#ip_address_specifications.

--allow-global-access

If True, then clients from all regions can access this internal forwarding rule. This can only be specified for forwarding rules with the LOAD_BALANCING_SCHEME set to INTERNAL or INTERNAL_MANAGED. For forwarding rules of type INTERNAL, the target must be either a backend service or a target instance.

--allow-psc-global-access

If specified, clients from all regions can access this Private Service Connect forwarding rule. This can only be specified if the forwarding rule's target is a service attachment (--target-service-attachment).

--description=DESCRIPTION

Optional textual description for the forwarding rule.

--disable-automate-dns-zone

If specified, then a DNS zone will not be auto-generated for this Private Service Connect forwarding rule. This can only be specified if the forwarding rule's target is a service attachment (--target-service-attachment=SERVICE_ATTACHMENT) or Google APIs bundle (--target-google-apis-bundle=API_BUNDLE)

--ip-collection=IP_COLLECTION

Resource reference to a public delegated prefix. The PublicDelegatedPrefix (PDP) must be a sub-prefix in EXTERNAL_IPV6_FORWARDING_RULE_CREATION mode.

--ip-collection-region=IP_COLLECTION_REGION

Region of the public delegated prefix to operate on. If not specified, the region is set to the region of the forwarding rule. Overrides the default compute/region property value for this command invocation.

--ip-protocol=IP_PROTOCOL

IP protocol that the rule will serve. The default is TCP.

Note that if the load-balancing scheme is INTERNAL, the protocol must be one of: TCP, UDP, ALL, L3_DEFAULT.

For a load-balancing scheme that is EXTERNAL, all IP_PROTOCOL options other than ALL are valid.

IP_PROTOCOL must be one of: AH, ESP, ICMP, SCTP, TCP, UDP, L3_DEFAULT, ALL.

--ip-version=IP_VERSION

Version of the IP address to be allocated or assigned. The default is IPv4. IP_VERSION must be one of: IPV4, IPV6.

--is-mirroring-collector

If set, this forwarding rule can be used as a collector for packet mirroring. This can only be specified for forwarding rules with the LOAD_BALANCING_SCHEME set to INTERNAL.

--load-balancing-scheme=LOAD_BALANCING_SCHEME
