Using Packet Capture

Packet Capture allows you to capture and examine the contents of individual data packets that traverse your SonicWALL firewall appliance. The captured packets contain both data and addressing information. The System > Packet Capture page provides a way to configure the capture criteria, display settings and file export settings, and displays the captured packets.

The Packet Capture screen has buttons for starting and stopping a packet capture. If you simply click Start without any configuration, the SonicWALL appliance will capture all packets except those for internal communication, and will stop when the buffer is full or when you click Stop.
