QVPN Service creates a log entry every time a user accesses a VPN server. The connection logs
include the connection method, date, time, username, source IP, and content.
Note: QVPN Service only displays the connection logs. To copy or delete a log, or to
export the list, go to “Control Panel” > “System” > “System Logs”.
