## Overview

If you have not yet registered for the service, you can do so by visiting our registration page. Connect to the control panel by entering the IP address of the Bright Box router in the address bar of any browser. Then, log in by entering your administrative credentials.

## Configure the Device DNS

First, you need to change the DNS of the device. To do this, click on the **Advanced** tab at the top of the page and open the **Broadband Settings** menu.

In the window that appears, choose MANUAL under the DNS IP Address section, and type our cloud IPs into the specific fields respectively:

- **Primary DNS:** 185.236.104.104
- **Secondary DNS:** 185.236.105.105

Click on the **SAVE SETTINGS** button to apply the changes.

## Configure Dynamic DNS Service

To configure the Dynamic DNS service, open the **System** menu and click on **DDNS**. Check the Dynamic DNS box and fill in the various fields exactly as follows:

- **Provider:** Select DYNDNS.org.
- **Domain name:** Type in the [domain](https://fsflt.com).
- **Account and Email:** Enter the specific username assigned to your dynamic network inside our dashboard. Do not use your main registration email.
- **Password and Key:** Enter the specific password assigned to your dynamic network.

Click the **SAVE SETTINGS** button to save the changes and force the synchronization.

## Enable the DHCP Server

At this point, you can enable the DHCP server to automatically distribute network parameters to your internal network devices.

Open the **DHCP** menu and enable the DHCP Server item. Choose a lease time and enter the first and last IP address of your local DHCP range.

:::hint{type="info"}
The DHCP server will distribute the local IP of the router as the only DNS for your clients. This will not cause any problems since our cloud IPs have already been configured as the primary DNS of the router itself, ensuring all outbound network traffic is correctly routed and filtered.
