cannot email the log file, the log buffer might fill up. In this case, the

wireless modem router overwrites the log and discards its contents.

Log the Network Activity

A log is a detailed record of the websites that users on your network have accessed or

attempted to access. If you have set up content filtering on the Block Sites screen, the Logs

screen shows you when someone on your network tried to access a blocked site. If you have

email notification on, you will receive these logs in an email message. If you do not have

email notification set up, you can view the logs on the Logs screen.



To log the network activity:

1.

Select

Content Filtering > Logs

to display the Logs screen:

Selecting all check boxes will increase the size of the log, so it is good practice to disable

any events that are not really required.

•

Attempted access to blocked sites
