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.
