How to Change the Root Password and Management ACL

  • Last updated on

The root password is used for the superuser root. The user root can log into the basic subsystems and OS. Unless set during deployment, the default root password is ngf1r3wall. Change the root password immediately after the first login.

The management ACL specifies which IP addresses can access the system. Use the management access control list to whitelist networks that are allowed to connect to the firewall. Only these whitelisted networks are allowed access to the management IPs on TCP ports 22 (secure shell) and 800-820. Access from all other addresses to these port/addresses are denied.

Change the Root Password

Passwords can consist of small and capital characters, numbers, and non-alpha-numeric symbols except #, &, § and spaces. Barracuda Firewall Admin rates the password strength according to the entered characters.

  1. Go to BASIC > Administration.
  2. In the PASSWORD CHANGE section, enter the Old Password.
  3. In the New Password field, enter the new password for the root user.
  4. Click Save.

Management Access Control List

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 BASIC > Active Connections page.

Misconfigurations of the Access Control Lists render the web interface inaccessible. The only way to revert this change is to log into the physical console of the system and follow the instructions from Barracuda Networks Technical Support to manually recover connectivity.

  1. Go to BASIC > Administration.
  2. In the MANAGEMENT ACL section, add IPv4 networks and/or IP addresses that are allowed to manage the firewall. Click Add after each entry.
  3. Click Save.
