Barracuda CloudGen Firewall

Administration

  • Last updated on

You can use existing services in your network, such as DNS or NTP servers, when deploying the CloudGen Firewall. Initially, every CloudGen Firewall is managed by the user root who has unlimited access rights to the entire system when logged into the interface. The firewall supports multiple administrators and can restrict access based on source IP address or network. 

Administrators

The user root has the ability to grant system access to other administrators by adding them to the Management Access Control List. The Management ACL specifies which IP addresses can access the system. In the system access configuration, you can also change the password for the root user.

For more information, see How to Change the Root Password and Management ACL.

DNS

Configure the firewall to manage either a network DNS server or a DNS server assigned by your ISP. When resolving DNS requests, the firewall can redirect or block queries for specific domains by using blacklisting and whitelisting. You can use the same namespace internally and externally, and redirect external clients to use one IP address, and internal clients to use an internal path to the same hostname (Split DNS). DNS queries can be forwarded to or cached from the DNS server.

For more information, see How to Configure DNS Settings.

NTP

You can define one or more NTP server(s) to act as a master clock for the firewall. The current time on the system is synchronized via Network Time Protocol (NTP). Time settings apply to all time-related services on the firewall and affect data accounting, logging, and event notifications. Correct time settings are also important for high availability (HA) synchronization.

For more information, see How to Configure Time Server (NTP) Settings.

Email Notifications

Some services, such as the Virus Scanner, can send email notifications. You can configure the email address and the SMTP server used for email notifications.

For more information, see How to Configure System Email Notifications.
