FortiView — subnet filters

In FortiView, you can filter source IPs or destination IPs with a subnet mask using the x.x.x.x/x format. You can view the results in real-time or historical mode.

Both logging from disk and logging from FortiAnalyzer are supported.

Sample configuration of filtering IPs with a subnet mask

This example shows how to filter destination IPs with a subnet mask using the x.x.x.x/x format.

To filter destination IPs with a subnet mask:

1. Go to FortiView > Destinations.
2. Click Add Filter.
3. In the dropdown menu, select Destination IP.
4. Enter the subnet mask (in the example, 91.189.0.0/16).
5. Press the Enter key. The filter results display.

To view results in the backend subnet filter:
