GCP Compute Forwarding Rule

A Google Cloud forwarding rule represents a single IP address and port or range of ports that forwards incoming traffic to a specific target resource such as a backend service or load balancer. Forwarding rules are created as part of load-balancing configurations and determine where packets that match the rule’s protocol, IP and port are delivered. They can be regional (for internal traffic or regional external load balancing) or global (for global external load balancing).

gcp-compute-network​

A forwarding rule is always associated with a VPC network. The network defines the address space within which an internal forwarding rule exists, or provides the egress path for an external forwarding rule.

gcp-compute-backend-service​

For load-balancing use-cases, the forwarding rule directs traffic to a backend service. Inspecting this link lets you see the collection of instance groups or endpoints that ultimately receive the traffic.

ip​

The forwarding rule reserves or references a specific external or internal IP address. Linking to the IP resource shows ownership and helps detect address conflicts across multi-cloud inventories.

gcp-compute-subnetwork​

When the forwarding rule is internal, it must reside in a particular subnetwork within its VPC. This link identifies the subnetwork that scopes the rule’s address range and reachability.
