Is it possible to get a report or a log showing the users that get access to Internet and from what IP that users were connecting.ADDITIONAL INFORMATION:
I have an RF660VPN configured to allow users to access the Internet using the local authentication of the RF660. It is probable that an unauthorized employee is using a username and password that is not authorized to get Internet access.
If you have HTTP proxy enabled, you can view the HTTP access log in the Statistics and Logs screen. The access log will only show IP addresses and not the usernames.
