Managing the WANJet Appliance


WANJet appliance authentication settings

To maintain the security of the WANJet appliance settings, the Web UI is password-protected, while the LCD menu on the front of the appliance is PIN-protected. You can change the password and/or PIN code at any time. F5 Networks recommends that you immediately change the password and PIN code from the defaults and then change them regularly (once a month, for example) thereafter.

Changing the Web UI password

The admin user account password is the only local account that you can use to access the Web UI. You can use remote accounts to access the Web UI; however, you cannot change the passwords for remote accounts from the WANJet Password screen. For more details, refer to Configuring remote authentication , following.

Important

Since there is only one local password for the Web UI, be sure to warn all other users that you are changing the password (unless they are using remote authentication).

To change the WANJet Web UI password

  1. In the navigation pane, expand Security and click Password.
    The WANJet Password screen displays.
  2. In the Old Password box, type the old password.
    • Note: If you did not change the default password during the initial configuration, leave this box blank.
  3. In the New Password box, type the new password.
    As a general rule, passwords should consist of at least 6 characters and include a mixture of lowercase and uppercase letters, numbers, and punctuation marks. A blank password is not allowed.
  4. In the Confirm Password box, retype the new password.
    This must match the password that you typed in the New Password box.
  5. Click the Save button to save the new setting.
    A confirmation screen displays.
  6. Click Yes to confirm the new password.

Configuring remote authentication

You can choose to authenticate WANJet appliance users against the WANJet appliance's local database, or against a RADIUS remote authentication server.

To configure the WANJet appliance for local authentication

  1. In the navigation pane, expand Security and click Remote Authentication.
    The WANJet Remote Authentication screen displays.
  2. Click the button next to No Remote Authentication.
  3. Click the Save button.

To configure the WANJet appliance for remote RADIUS authentication

  1. In the navigation pane, expand Security and click Remote Authentication.
    The WANJet Remote Authentication screen displays.
  2. Click the button next to RADIUS.
  3. In the box under Server, type the IP address for the RADIUS server.
  4. In the box under Secret, type the server's shared secret.
    This is the key that authenticates RADIUS transactions between the client (the local WANJet appliance, in this case) and the RADIUS server.
  5. In the box under Timeout, type the number of seconds that the WANJet appliance should wait after sending a RADIUS request. After this time has expired, WANJet appliance stops waiting for a response. F5 Networks recommends that you use the value of 3.
  6. In the box under NRetry, type the number of times that you want the WANJet appliance to send a RADIUS request to the server before giving up. F5 Networks recommends that you use the value of 3.
    • Note: If you type a value in the Timeout box, you must also enter a value in the NRetry box. If you set the values too high, it could take a long time to determine that the server is not responding to a login attempt. This problem will be compounded if you are using more than one RADIUS server.
  7. Click the Add button to store the new information.
  8. Repeat Step 2 through 7 for any additional RADIUS servers.
    • Note: Once you have added server details, you cannot edit them. You must delete and the information and add it again.
  9. Click the Save button.
    The Remote Authentication screen refreshes with the RADIUS server details that you added.
Note

After you configure the WANJet appliance to use remote RADIUS authentication, you can view diagnostic RADIUS reports. For more information, see Connectivity for details about this report. For information about RADIUS protocol, refer to http://www.ietf.org/rfc/rfc2865.txt.

Changing the WANJet LCD PIN code

There is no default PIN code for the Liquid Crystal Display (LCD) on the WANJet appliance.

To create or change the LCD PIN code

  1. In the navigation pane, expand Security and click LCD PIN.
    The LCD PIN screen displays.
  2. In the Old PIN box, type the old PIN.
    This is a four-digit number.
  3. In the New PIN box, type the new PIN.
    This must be a four-digit number.
  4. In the Confirm PIN box, retype the new PIN.
    It must match the PIN that you typed in the New PIN box.
  5. Click the Save button.

Granting Web UI access

You can restrict or allow access to the WANJet appliance's Web UI, and the SNMP reports residing on it, to specific WANJet appliances or subnets as follows:

  • Allow all addresses (default)
    Provide access to all WANJet appliances or subnets residing on the network.
  • Allow Listed Addresses
    Provide access to specified WANJet appliances or subnets.
  • Deny Listed Addresses
    Prevent access for specified WANJet appliances or subnets, while allowing access from all other WANJet appliances or subnets residing on the network.

Once configured, if a restricted WANJet appliance attempts to access the Web UI, the browser returns a 404: Page Not Found error.
