23.4 Configuring Reports
The Reports page displays which computers on the LAN send and receive the most traffic,
what kinds of traffic are used the most and which web sites are visited the most often. Use the
Reports screen to have the ZyWALL record and display the following network usage details:
• Web sites visited the most often
• Number of times the most visited web sites were visited
• The most-used protocols or service ports
• The amount of traffic for the most used protocols or service ports
• The LAN IP addresses to and/or from which the most traffic has been sent
• How much traffic has been sent to and from the LAN IP addresses to and/or from which
the most traffic has been sent
Note: The web site hit count may not be 100% accurate because sometimes when an
individual web page loads, it may contain references to other web sites that
also get counted as hits.
The ZyWALL records web site hits by counting the HTTP GET packets. Many web sites
include HTTP GET references to other web sites and the ZyWALL may count these as hits,
thus the web hit count is not (yet) 100% accurate.
