When doing packet capture for troubleshooting network related issues, sometimes we may not be able to see packets captured on SonicWall even if the packet monitor utility is configured properly. This article shows the possible reason for the problem & provides a way to overcome it.
Step 1: Login to the SonicWall GUI.
Step 2: Navigate to System | Packet Monitor page in the GUI. You can see Trace active along with Buffer Size and Packets captured ("zero" in this case). In the same page, you could see a note stating "Capture filter based on firewall/app rule".
Step 3: Click on Configure option in the packet monitor page.
Step 4: Navigate to Monitor Filter tab and disable the check box "Enable filter based on the firewall/app rule".
Step 5: Also ensure that, you have configured the Display Filter tab and Advanced Monitor Filter tab as shown in the below screen shots.
Step 6: Click on OK.
- Try to send appropriate traffic and the respective packets would be captured by SonicWall as per the packet monitor configuration & you can see it in the System | Packet Monitor page.
