 5: Using System Administration

The Firewall Name uniquely identifies the SonicWALL security appliance and defaults to the serial 
number of the SonicWALL security appliance. The serial number is also the MAC address of the unit. 
The Firewall Name is mainly used in e-mailed log files. To change the Firewall Name, enter a unique 
alphanumeric name in the Firewall Name field. It must be at least 8 characters in length.

The Administrator Name can be changed from the default setting of admin to any word using 
alphanumeric characters up to 32 characters in length. To create an new administrator name, enter 
the new name in the Administrator Name field. Click Apply for the changes to take effect on the 
SonicWALL security appliance. 

To set the password, enter the old password in the Old Password field, and the new password in the 
New Password field. Enter the new password again in the Confirm New Password field and click 
Apply. Once the SonicWALL security appliance has been updated, a message confirming the update 
is displayed at the bottom of the browser window.

The Log out the Administrator after inactivity of (minutes) setting allows you to set the length of 
inactivity time that elapses before you are automatically logged out of the management interface. By 
default, the SonicWALL security appliance logs 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 Log out the Administrator after inactivity of (minutes) 
setting and click Apply. The time range can be from 1 to 99 minutes. Click Apply, and a message 
confirming the update is displayed at the bottom of the browser window.

You can configure the SonicWALL security appliance to lockout an administrator or a user if the login 
credentials are incorrect. Select the Enable Administrator/User Lockout check box to prevent users 
from attempting to log into the SonicWALL security appliance without proper authentication 
credentials. Enter the number of failed attempts before the user is locked out in the Failed login 
attempts per minute before lockout field. Enter the length of time that must elapse before the user 
attempts to log into the SonicWALL security appliance again in the Lockout Period (minutes) field.

Alert: If the administrator and a user are logging into the SonicWALL security appliance using the 
same source IP address, the administrator is also locked out of the SonicWALL security appliance. 
The lockout is based on the source IP address of the user or administrator.
