# Other settings

## Custom CA certificates

The Efento Gateway comes with several commonly used **preloaded CA certificates**. If you wish to use a **custom CA certificate**, you can upload it through the gateway by navigating to **Settings > CA Certificates**.

Efento Gateway supports any certificate in PEM format. For security reasons, we strongly recommend using certificates signed by a trusted Certification Authority. However, for development or demonstration purposes, you may also [use a self-signed certificate](/efento-gateways/integration/self-signing-ca-certificate.md).

## Proxy

The Efento Gateway can connect to **Efento Cloud** or a **third-party server** through a proxy server. By default, the proxy feature is **disabled**. Efento Cloud supports both **anonymous** and **non-anonymous** proxy servers.

To configure proxy settings:

1. Go to the **Settings > Proxy** tab.
2. Select the **proxy type**.
3. Enter the **server address** and **port**.
4. If using a **non-anonymous proxy**, provide the **login credentials**.

These settings allow the gateway to communicate with the server securely and reliably through your network’s proxy.

## Encryption

Communication between Efento loggers and the Efento Gateway can be **encrypted** using a user-defined key. When encryption is enabled, only devices that have the correct key can decode the transmissions and read loggers measurements.

The gateway allows you to add up to **five encryption keys**. Once a key is added, the gateway can decrypt and read measurements from all loggers using that same key. Encryption keys for loggers can be [configured using the **Efento mobile application**](/efento-ble-loggers/using-loggers/standalone-mode/logger-settings.md#encryption).

## Password

In the **Settings** > **Password** tab, you can change the gateway’s login password. To update the password, enter the **new password twice** and provide the **current password** for verification. It is **strongly recommended** to change the password during the initial gateway configuration to ensure secure access.

## Reset

The **Settings > Reset** tab allows you to manage the gateway’s restart and factory reset functions:

* **Restart the Gateway:** The device will power off and on again without affecting any existing settings or configurations.
* **Reset the Gateway:** The device will restore **factory default settings**. All custom configurations will be lost, and the gateway will need to be reconfigured.

A factory reset can also be performed using the physical button on the back of the gateway:

* **Older models:** Press and hold the button for **10 seconds**.
* **Newer models:** Press the button **7 times** in succession.

## 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://docs.efento.io/efento-gateways/ethernet-gateway/other-settings.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.
