| Solution ID | sk165732 |
| Date Created | 2020-03-12 |

| Technical Level | General |
| Products | Cloud Firewall |
| Versions | R82.10, R81.20, R82 |
| OS | Gaia |
| Platform | Azure |

## Symptoms

- The following drops are observed on Azure Gateways when debugging for drops:   

```

@;289735852;[cpu_1];[fw4_0];fwha_handle_cloud_probe: dropping cloud probing request on eth1 (2);

@;289735852;[cpu_1];[fw4_0];fwha_handle_cloud_probe: dropping cloud probing request on eth0 (1);
```

## Cause

This behavior is by design.  

Cloud load balancer health probe packets are replied to by fw kernel and then the packet is dropped for performance considerations.  

As a result, the kernel level debugs show that the packets are dropped.

<br />

## Solution

This is an expected behavior: The drops are part of a performance consideration.  

To make sure certain health probe traffic is working correctly, run the following command:  

For HA cluster: '*# fw ctl zdebug -m cluster cloud* '  

For VMSS or a single Gateway: '*# fw ctl zdebug highavail* '
