This article explains what firewall packet
logging is and how to use it.
If programs have problems accessing the Internet, it is useful to see
what is happening on the firewall by creating a packet log. The packet log
collects information about the IP network traffic. By default, packet logging
is turned off. Packet logging is mainly aimed at experienced users who are
familiar with computer networks. You can turn packet logging on if you have
created your own set of firewall rules, and want to check how they block
traffic. You can also do this if you suspect malicious network activity.
Information is gathered into ten files (packetlog.0 - packetlog.9).
Each time you turn on the logging, the packet log is collected into a new file.
Once the tenth file becomes full, the next log is collected again to the first
file. In this way, you can view the previous logs while a new log is generated.
For more detailed information about the packet log contents, see the
product online help. If necessary, you can send the log file also to our
technical support for further analysis.

contains 10 log files, the next log is gathered into an existing file.
