Справочное Руководство для Netopia r3100-u

When you first set up and configure the Netopia R3100, no passwords are required to access the configuration 
screens. Anyone could tamper with the router’s configuration by simply connecting it to a console.

However, by adding user accounts, you can protect the most sensitive screens from unauthorized access. User 
accounts are composed of name/password combinations that can be given to authorized users.

You are strongly encouraged to add protection to the configuration screens. Unprotected screens could allow an 
unauthorized user to compromise the operation of your entire network.

Once user accounts are created, users who attempt to access protected screens will be challenged. Users who 
enter an incorrect name or password are returned to a screen requesting a name/password combination to 
access the Main Menu.

To set up user accounts, select Security in the System Configuration screen and go to the Security Options 
screen.

The first screen you should protect is the Security Options screen, because it controls access to the 
configuration screens. Access to the Security Options screen can be protected with a password. 

Select Password for This Screen in the Security Options screen and enter a password. Make sure this 
password is secure and is different from any of the user account passwords.

You can protect the configuration screens with user accounts. You can administer the accounts from the 
Security Options screen. You can create up to four accounts.
