What are logs?
Most Routers keep logs of all kinds of activity both inbound and outbound. Some, like most Netgears, can be configured to email the logs to you at specific intervals or when certain types of activity occur. Other Routers like Linksys and Netcomms have an external application (downloadable from the manufacturer) that collects the log data from the Router and displays it in various ways. (For these types of Routers there will be a page where you can turn logging on and specify the IP address of the PC running the logging application). Other people have written their own versions of these logging applications that can display the data in lovely graphs and tables. See Wallwatcher for Linksys Linklogger for Netgear, Linksys & Zyxel.
