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 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 addresss to Network3.
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.
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.
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.
CLOUD_SQL_INSTANCE_UNAUTHORIZED_ACCESS
value: 17
Access to the Cloud SQL instance endpoint is not authorized.
See Authorizing with authorized
networks for
more details.
DROPPED_INSIDE_GKE_SERVICE
value: 18
Packet was dropped inside Google Kubernetes Engine Service.
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.
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.
