# Unable to Reach On-Prem Management Plane

## Problem

* Unable to access on-prem management plane from browser or through API calls.

## Environment

* Platform9 Edge Cloud - All Versions

## Cause

* The IP forwarding is disabled manually on the host running the management plane. Any request coming for the management plane VM on the host are not getting forwarded to the management plane.
* By default it is enabled on the host running the management plane as a pre-requisite for hosting the management plane.
* Below command confirms the IP forwarding is disabled on the host.

{% tabs %}
{% tab title="Sample Output" %}

```none
$ sudo sysctl -p | grep forward
net.ipv4.ip_forward = 0
```

{% endtab %}
{% endtabs %}

## Resolution

1. Enable the kernel parameter for IPv4 packet forward by running the below command.

{% tabs %}
{% tab title="None" %}

```none
$ sudo sysctl -w net.ipv4.ip_forward=1
net.ipv4.ip_forward = 1
```

{% endtab %}
{% endtabs %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://platform9.com/kb/smcp/solution/unable-to-reach-mangement-plane.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
