Network Discovery

If your Firebox runs Fireware OS v11.11 or higher and includes an active subscription to the Network Discovery feature in the feature key, on the Dashboard > Network Discovery page, you can see a tree map view of all the devices on your network that are connected to the interfaces on your Firebox. You can see this detailed information for each connected device:

  • IP address
  • MAC address
  • Host name
  • Operating system
  • Open ports
  • Device type (for devices found by Mobile Security)

Network Discovery is only supported on Firebox M Series, T Series, FireboxV, and XTMv devices.

When you enable the Network Discovery feature on your Firebox, the process load increases and consumes additional memory. This could noticeably affect the performance of your Firebox, particularly if you have a large network. Make sure to only enable the Network Discovery feature if you plan to use it. To help minimize the performance impact on your Firebox, WatchGuard recommends that you configure the Network Discovery Scan settings to only scan the networks that you must monitor.

See Devices on Your Network

The Network Map is organized by interface, in a tree map. Interfaces are on the first level, subnets are on the second level, and devices are on the third level. Each interface can have several subnets.

The connections between interfaces, subnets, and devices are indicated by the branch lines of the tree map. If there are distant network connections to your network, they appear at the last level, behind a device, and appear as a dotted line, which indicates that there could be more than one connection between the device directly connected to you network and the endpoints.

Run a Scan

To see the devices on your network, if you are logged in with Device Administrator credentials, you can run a scan that finds all the devices connected to your network. You can schedule a scan to run automatically, or run an on-demand scan. Scan times can vary based on network conditions, which can include the size of your network, how many hosts are active, and how many services are enabled. On-demand scans take longer to complete than scheduled scans.

An on-demand scan has three stages:

  • Quick Host discovery phase — Finds basic information about each device to organize the interfaces and connected devices in the map
  • TCP and OS phase — Finds more detailed information, such as the TCP port and the OS on the device
  • UDP and Service Version phase — Finds the UDP port and services versions

To schedule a scan, configure the Network Scan settings, which specify the interfaces that are included in the scan and at what frequency the scan runs.

For more information about how to configure scheduled scan settings or run an on-demand scan from the Network Scan page, see Network Discovery.

To run an on-demand scan from the Network Discovery page:

  1. At the top-right of the Network Discovery page, click Scan Now.
    The Scan Now dialog box appears.

  1. From the drop-down list, select a scan option:
  2. If you selected Scan the following interfaces, select the check box for each interface to scan.
    If you selected Scan the following networks, type each network to scan and click Add.
  3. Click Scan.
    The Firebox runs the network scan.

To stop an on-demand scan before it completes:

At the top-right of the page, click Stop Scan.

See Scan Details

While the network scan runs, you can view the details of the progress of the scan. Details include:

To see scan details:

  1. At the top-right of the page, click Show Details.
    The Scan Details dialog box appears.

  1. Review the details of the current scan.
  2. Click OK.

After the network scan has completed, the devices appear in the Network Map and Devices List tabs. Devices remain in the map and list until they are removed because:

  • A new on-demand or scheduled scan does not find the device
  • No on-demand or scheduled scan has run for seven days
  • No traffic was found for a mobile device for more than two hours; a mobile device is removed from the map after seven days with no response

Use the Network Map

After a manual or scheduled scan has completed, you can use the Network Map to see all the devices connected to your network and see details about each connected device.

Review the Device List

On the Device List tab, you can see all of the devices connected to your network in a tabular list format.

Screen shot of the Device List tab

The list includes this information for each device:

  • Status — The status of the device at the last scan and, if available, a scan details indicator icon.
    • the Green Cross icon — The device was found on the network the last time it was scanned.
    • the Green Dot icon — The device has sent traffic in the last two hours.
    • the Yellow Dot icon — The device has not sent traffic in the last two hours.
    • If Mobile Security is enabled, and the device was discovered by a Mobile Security scan, a device-specific icon appears.
  • Device — The name of the device. If the device name cannot be detected, a host name or IP address appears in this column.
  • IP Address — The IP address of the device.
  • Device Type — The type of device. For a mobile device, the type of mobile device appears, such as Android or iPhone. If the device type is not available, this column is empty.

Edit Device Details and Forget a Device

To make it easier to identify those devices that often appear in the Network Map, you can edit the details for the devices in the map to add a name and a description. You can also specify whether a device is an Approved Device. An Approved Device remains in the Network Map when it is offline. Offline devices that are approved appear in the Idle Devices branch of the Network Map. The details you specify for a device are saved in the device configuration file for your Firebox.

You can edit the device details from the device information dialog box or from any of the device Details pages. For an approved device, you can change the device details that you specified, or forget the device so it is no longer approved.

To edit the device details for a device that is not approved:

  1. Click Remember Device.

Example of the Remember device button on the device information dialog box.

Example of the Remember device button on the Details page.

The Edit Device dialog box appears.

  1. In the Name text box, the name from the device automatically appears. You can type a new, friendly name to help you identify the device.
  2. In the Description text box, type a brief description of the device.
  3. To specify that the device is approved, and enable it to appear in the Idle Devices branch when it is offline, select the Approved Device check box.
  4. Click OK.

When you select to remember a device, the Edit and Forget buttons appear in the device information dialog box and on the details page in place of the Remember Device button. If you selected to approve the device, the Approved Device label appears below the device icon.
