Hi, the traffic statistics between the various reports don't agree. If you have a look at the figures in the web page report summary, then compare them with the figures in the network page summary for http and http-alt they don't agree.
"Network Accounting" takes the toal IP traffic (including IP, TCP and HTTP headers), whereas "Web Security" reports on HTTP content (which is, obviously, less than the total IP traffic).
