How to Change the Root Password and Management ACL

  • Last updated on

Restricting access to the management interface of the Barracuda NG Firewall is important for network security. Barracuda Networks strongly recommends changing the root password after the first login. Use the management access control list to whitelist IP addresses that are allowed to connect via NG Admin to the Barracuda NG Firewall or NG Control Center.

In this article:

Change the Root Password

  1. Open the Administrative Settings page (Config > Full Config > Box).
  2. In the left menu, click System Access.
  3. Click Lock.
  4. In the Root Password section, enter the password for the root user.

    Passwords can consist of small and capital characters, numbers, and non alpha-num symbols. Barracuda NG Admin rates the password strengh according to the entered caracters. For more information, see the NG Admin password strength policy in Configuration Pages - Access and Controls.

  5. Click Send Changes and Activate.

Manage the Management Access Control List

Enter the IP addresses or networks for which access to the management IP on TCP ports 22 (secure shell) and 800-820 is granted. Access from all other addresses to these port/addresses are denied. By default, access is allowed from an arbitrary address. Changing the ACL does not terminate active admin sessions. To enforce ACL changes, manually terminate active sessions on the Firewall > Sessions page.

  1. Open the Administrative Settings page (Config > Full Config > Box).
  2. In the left menu, click System Access.
  3. Click Lock.
  4. In the Access Control List section, click + and add the IP addresses from which the Barracuda NG Firewall can be administered.
  5. Click Send Changes and Activate.
