Using Packet Sniffer
The ZoneAlarm router includes the Packet Sniffer tool, which enables you to capture
packets from any internal network or ZoneAlarm port. This is useful for troubleshooting
network problems and for collecting data about network behavior.
The ZoneAlarm router saves the captured packets to a file on your computer. You can use
a free protocol analyzer, such as Ethereal or Wireshark, to analyze the file, or you can send
it to technical support. Wireshark runs on all popular computing platforms and can be
downloaded from http://www.wireshark.com.
