VPN Traffic Not Being Monitored

Symptom

DU Meter doesn't show traffic when connected to a VPN, or shows incorrect/partial traffic data.

Cause

VPN software creates virtual network adapters. DU Meter needs to monitor the correct adapter to capture VPN traffic.

Solution

Step 1: Identify the VPN Adapter

  1. Connect to your VPN
  2. Press Win+R, type ncpa.cpl and press Enter
  3. Look for the adapter that appeared or changed status when you connected

Step 2: Configure DU Meter

  1. Right-click the DU Meter icon → select User Options
  2. Select Network Interface from the categories on the left
  3. Select "All network interfaces combined" to monitor all traffic
  4. Alternatively, select your specific VPN adapter
  5. Click OK

Note

If your VPN uses split tunneling (some traffic goes through VPN, some doesn't), you may need to monitor "All network interfaces combined" to capture everything.
