# Troubleshooting Managed Service for Kubernetes pod access via Network Load Balancer


## Issue description {#issue-description}

You cannot get access to applications in the Managed Service for Kubernetes cluster via Network Load Balancer endpoints.
  
## Solution {#issue-resolution}

If you use a load balancer that is associated with a security group, you need to create a rule in this group allowing traffic from the load balancer to Managed Service for Kubernetes cluster nodes on ports in the range from `30000` to `32767`.

{% note info %}

When routing traffic, the load balancer only changes the destination port, while the original IP address of the query remains the same. Therefore, you should specify the `0.0.0.0/0` address range in the allow rule.

{% endnote %}

## If the issue persists {#if-issue-still-persists}

If the above actions did not help, [create a support ticket](https://center.yandex.cloud/support). In your request, provide the following information:

1. Network Load Balancer ID.
1. Managed Service for Kubernetes cluster ID.
1. Information about pods running your applications that require network access via a load balancer, and the ports they receive traffic on.
