Troubleshooting for Zenarmor Device Identification
Most frequently seen Zenarmor Device Identification issues and their solutions are given below.
Only one device, which has a name that keeps changing, is shown in the devices menu.
The Devices menu displays a single device with a frequently changing name (hostname). It appears as if multiple devices are merged into one, making it difficult to track individual clients behind that device.
Root Cause
(Default Behavior - Router Device Disabled)
By default, when traffic passes through a Layer 3 (L3) device, Zenarmor captures all traffic associated with that device's MAC address, regardless of the different IP addresses using it. Zenarmor consolidates this information under a single device entry, updating the hostname and other details continuously based on the most recent observed data. This behavior is expected when a router, access point, or NAT-enabled device is present in the network and Router Device detection is not enabled. As a result, all traffic from devices connected behind the router is considered part of a single device, causing the device name to change dynamically.
Solution
Enable the Router Device option for the corresponding device. This instructs Zenarmor to treat the device as a router and to identify all connected clients individually based on their unique IP addresses.
You may enable Router Device by following the next steps.
- Go to Devices menu on Zenarmor UI.
- Find the device which has a name that keeps changing.
- Click on the device.
- Toggle the Router Device option to enable it on the right side pane.
- Save your changes.
Once enabled, Zenarmor will start recognizing and listing each connected client behind the router as a separate device, maintaining their individual hostnames and traffic data.
