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.
