Reference documentation and code samples for the Network Management V1 API module Google::Cloud::NetworkManagement::V1::DropInfo::Cause.

Drop cause types:

Constants

CAUSE_UNSPECIFIED

value: 0
Cause is unspecified.

UNKNOWN_EXTERNAL_ADDRESS

value: 1
Destination external address cannot be resolved to a known target. If the address is used in a Google Cloud project, provide the project ID as test input.

FOREIGN_IP_DISALLOWED

value: 2
A Compute Engine instance can only send or receive a packet with a foreign IP address if ip_forward is enabled.

FIREWALL_RULE

value: 3
Dropped due to a firewall rule, unless allowed due to connection tracking.

NO_ROUTE

value: 4
Dropped due to no matching routes.

ROUTE_BLACKHOLE

value: 5
Dropped due to invalid route. Route's next hop is a blackhole.

ROUTE_WRONG_NETWORK

value: 6
Packet is sent to a wrong (unintended) network. Example: you trace a packet from VM1:Network1 to VM2:Network2, however, the route configured in Network1 sends the packet destined for VM2's IP address to Network3.

ROUTE_NEXT_HOP_IP_ADDRESS_NOT_RESOLVED

value: 42
Route's next hop IP address cannot be resolved to a GCP resource.

ROUTE_NEXT_HOP_RESOURCE_NOT_FOUND

value: 43
Route's next hop resource is not found.

ROUTE_NEXT_HOP_INSTANCE_WRONG_NETWORK

value: 49
Route's next hop instance doesn't hace a NIC in the route's network.

ROUTE_NEXT_HOP_INSTANCE_NON_PRIMARY_IP

value: 50
Route's next hop IP address is not a primary IP address of the next hop instance.

ROUTE_NEXT_HOP_FORWARDING_RULE_IP_MISMATCH

value: 51
Route's next hop forwarding rule doesn't match next hop IP address.

ROUTE_NEXT_HOP_VPN_TUNNEL_NOT_ESTABLISHED

value: 52
Route's next hop VPN tunnel is down (does not have valid IKE SAs).

ROUTE_NEXT_HOP_FORWARDING_RULE_TYPE_INVALID

value: 53
Route's next hop forwarding rule type is invalid (it's not a forwarding rule of the internal passthrough load balancer).

NO_ROUTE_FROM_INTERNET_TO_PRIVATE_IPV6_ADDRESS

value: 44
Packet is sent from the Internet to the private IPv6 address.

VPN_TUNNEL_LOCAL_SELECTOR_MISMATCH

value: 45
The packet does not match a policy-based VPN tunnel local selector.

VPN_TUNNEL_REMOTE_SELECTOR_MISMATCH

value: 46
The packet does not match a policy-based VPN tunnel remote selector.

PRIVATE_TRAFFIC_TO_INTERNET

value: 7
Packet with internal destination address sent to the internet gateway.

PRIVATE_GOOGLE_ACCESS_DISALLOWED

value: 8
Instance with only an internal IP address tries to access Google API and services, but private Google access is not enabled in the subnet.

PRIVATE_GOOGLE_ACCESS_VIA_VPN_TUNNEL_UNSUPPORTED

value: 47
Source endpoint tries to access Google API and services through the VPN tunnel to another network, but Private Google Access needs to be enabled in the source endpoint network.

NO_EXTERNAL_ADDRESS

value: 9
Instance with only an internal IP address tries to access external hosts, but Cloud NAT is not enabled in the subnet, unless special configurations on a VM allow this connection.

UNKNOWN_INTERNAL_ADDRESS

value: 10
Destination internal address cannot be resolved to a known target. If this is a shared VPC scenario, verify if the service project ID is provided as test input. Otherwise, verify if the IP address is being used in the project.

FORWARDING_RULE_MISMATCH

value: 11
Forwarding rule's protocol and ports do not match the packet header.

FORWARDING_RULE_NO_INSTANCES

value: 12
Forwarding rule does not have backends configured.

FIREWALL_BLOCKING_LOAD_BALANCER_BACKEND_HEALTH_CHECK

value: 13
Firewalls block the health check probes to the backends and cause the backends to be unavailable for traffic from the load balancer. For more details, see Health check firewall rules.

INSTANCE_NOT_RUNNING

value: 14
Packet is sent from or to a Compute Engine instance that is not in a running state.

GKE_CLUSTER_NOT_RUNNING

value: 27
Packet sent from or to a GKE cluster that is not in running state.

CLOUD_SQL_INSTANCE_NOT_RUNNING

value: 28
Packet sent from or to a Cloud SQL instance that is not in running state.

TRAFFIC_TYPE_BLOCKED

value: 15
The type of traffic is blocked and the user cannot configure a firewall rule to enable it. See Always blocked traffic for more details.

GKE_MASTER_UNAUTHORIZED_ACCESS

value: 16
Access to Google Kubernetes Engine cluster master's endpoint is not authorized. See Access to the cluster endpoints for more details.

DROPPED_INSIDE_CLOUD_SQL_SERVICE

value: 19
Packet was dropped inside Cloud SQL Service.

GOOGLE_MANAGED_SERVICE_NO_PEERING

value: 20
Packet was dropped because there is no peering between the originating network and the Google Managed Services Network.

GOOGLE_MANAGED_SERVICE_NO_PSC_ENDPOINT

value: 38
Packet was dropped because the Google-managed service uses Private Service Connect (PSC), but the PSC endpoint is not found in the project.

GKE_PSC_ENDPOINT_MISSING

value: 36
Packet was dropped because the GKE cluster uses Private Service Connect (PSC), but the PSC endpoint is not found in the project.

CLOUD_SQL_INSTANCE_NO_IP_ADDRESS

value: 21
Packet was dropped because the Cloud SQL instance has neither a private nor a public IP address.
