This article was written based on firmware version 4.3.0.
Cradlepoint’s Series 3 routers run the Linux software platform on firmware 4.0.3 and later, and one of the features of this software is to allow the router to divide the network into a number of segments. The advantage of this network segmentation is that you are allowed to specify in the configuration of the individual networks which router interfaces are to be a part of the network.
For example, an MBR1400 can be configured with two networks, one called CORPORATE, and the other GUEST. The networks can be configured as such:
CORPORATE: Interfaces (LAN 1, 2, 3, wireless SSID: CORP-NET)
GUEST: Interfaces (LAN 4, wireless SSID: GUEST-NET)
This is just one example of the advantages of network segmentation.
Once you’re logged into the Setup pages of the router (if you need help logging in to the Setup Pages of the CradlePoint, please click here),
Click Network Settings > Wifi/Local Networks. Below is a screenshot of this page.
For the scenario described above, we will need to create additional Ethernet Port Groups for each network that we want configured. Ethernet Port Groups can be configured in a number of different ways and is entirely up to the user to specify how this is configured. In the box called Local Network Interfaces, click the “Ethernet Port Configuration” tab.
By default there are two port groups already configured: lan and wan. Once on this page
1. Click Add
2. Specify a Port Group ID for your new group
3. Move the desired port(s) into the “Selected” field
4. Click Submit, and approve any additional prompts
Now, we are ready to associate our Ethernet port group with a network.
1. Click the check box next to “Guest LAN” and then Edit
2. Make any changes needed in the IP Settings tab, such as name or IP address
3. Click the Interfaces tab. You can see by default, the only selected interface for this Guest LAN is WiFi: Public-b16
4. Select our new Ethernet group “Guest”, and move it to the “Selected” field, as shown below. Click Submit. The router will inform you if the setting was applied successfully.
You can see now that the Ethernet group for Guest LAN (192.168.10.1) will now use Ethernet port 4 on the router as part of the group. There are a number of additional configurations that can be made to the individual IP Networks to differentiate them. These are configured in the Local Network Editor.
Network segmentation is not just limited to creating Primary and Guest networks, but can also be used to create networks for specific applications, such as VoIP. For larger scale switching, Ports and network segments can be configured with VLAN tagging to create VLANs across multiple switches.
