Setting up a VLAN on OpenWRT for a FritzBox 7490

In this article, we will discuss how to set up a VLAN (Virtual Local Area Network) on OpenWRT for a FritzBox 7490. This will allow you to segment your network, improving security and organization.

Prerequisites

Before we begin, make sure you have the following:

• A FritzBox 7490 router with DSL internet connection
• A NAS (Network Attached Storage) device with IP address 192.168.0.3
• An LXC container running an HTTP server
• OpenWRT installed on your router

Accessing the OpenWRT Web Interface

To access the OpenWRT web interface, connect your computer to one of the LAN ports on the FritzBox and open a web browser. Navigate to http://192.168.0.1 and log in using your administrator credentials.

Creating a VLAN

To create a VLAN, follow these steps:

1. Click on Network > Switch
2. Click on Create new VLAN
3. Enter a name for your VLAN (e.g., "VLAN1")

4. Select VLAN as the protocol
5. Select the VLAN you created earlier
6. Click Save & Apply
7. Configure the IP address for the interface (e.g., 192.168.10.1 with a netmask of 255.255.255.0)
8. Click Save & Apply

Assigning Devices to the VLAN

To assign devices to the VLAN, follow these steps:

1. Click on Network > DHCP
2. Click on Change DHCP subnet
3. Select the interface you created earlier
4. Enter the range of IP addresses for the VLAN (e.g., 192.168.10.100 to 192.168.10.200)
5. Click Save & Apply
6. Connect the devices you want to assign to the VLAN to one of the LAN ports on the FritzBox
7. Restart the devices

Testing the VLAN
