Setting the Administrator Inactivity Timeout
The Administrator Inactivity Timeout setting allows you to configure the length of inactivity that can
elapse before you are automatically logged out of the Web Management Interface. The SonicWALL
is preconfigured to log out the administrator after 5 minutes of inactivity.
Tip If the Administrator Inactivity Timeout is extended beyond 5 minutes, you should end every
management session by clicking Logout to prevent unauthorized access to the SonicWALL Web
Management Interface.
Enter the desired number of minutes in the Administrator Inactivity Timeout section and click
Update. The Inactivity Timeout can range from 1 to 99 minutes. Click Update, and a message
confirming the update is displayed at the bottom of the browser window.
Login Failure Handling
You can configure the SonicWALL to lockout an administrator or a user if the login credentials are
incorrect. Select Enable User Lockout on login failure to prevent users from attempting to log into
the SonicWALL without proper authentication credentials. Enter the number of failed attempts
before the user is locked out in the Lock out user after __ failed login attempts in a 1 minute period
field. Enter the length of time that must elapse before the user attempts to log into the SonicWALL
again in the Lockout Period (minutes) field.
Alert If the administrator and a user are logging into the SonicWALL using the same source IP
address, the administrator is also locked out of the SonicWALL. The lockout is based on the source
IP address of the user or administrator.
