+module: gcp_compute_forwarding_rule
+description:
+    - A ForwardingRule resource. A ForwardingRule resource specifies which pool of target
+      virtual machines to forward a packet to if it matches the given [IPAddress, IPProtocol,
+      portRange] tuple.
+short_description: Creates a GCP ForwardingRule
+version_added: 2.6

+            - 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, this can only be an RFC 1918 IP address
+              belonging to the network/subnet configured for the forwarding rule. By default,
