Barracuda Firewall - Overview The Barracuda Firewall is an application-aware network firewall appliance that is designed for organizations without dedicated IT personnel to manage firewalls. It leverages cloud resources to extend next-generation security and networking beyond the capabilities of typical security gateways or legacy firewalls.
Web Interface Adding source or destination networks, with netmasks higher than /24, to firewall rules now works as expected. (BNF-2869) The smart pre-submission input validation now also works correctly with DNAT firewall rules. It is now possible to access release notes for the latest general and early release through the > page.
What's New with Barracuda Firewall Version 6.1.3.003 Web Interface The Barracuda Firewall User Interface is now fully Japanese localized. Note that entering multi-byte characters is not yet supported. Guest networks for Wi-Fi networks can now only be configured in > (BNF-2650) USERS Guest Access.

SSL VPN is available at no additional cost for an unlimited amount of users. Depending on the performance level of the appliance model, Barracuda Networks recommends the following maximum numbers of users: Model Recommended Max.
High Availability All Barracuda Firewalls can now be deployed as part of a High Availability (HA) cluster. The primary unit handles all network traffic and security functions, while the secondary unit waits in standby mode to take over if the partner unit fails.
Configuration Wizards All Barracuda Firewalls now offer the following configuration wizards to guide you through initial setup and configuration: The wizard for initial activation and deployment in an evaluation and test scenario. This wizard starts automatically Test at my Desk during your first login.
Smart Pre-Submission Input Validation All Barracuda Firewalls now offer smart pre-submission input validation. This validation prevents configuration pop-ups from closing and losing entered information before all required fields are filled.
URL Filtering of HTTPS Websites and Web Security Service Exemptions All Barracuda Firewalls can now apply URL filtering provided by the Barracuda Web Security Subscription to websites accessed via HTTPS. Additionally, you can exempt user-defined domains or IP addresses from being forwarded to the Barracuda Web Security Service for HTTP and HTTPS.
Log Streaming All Barracuda Firewalls now support streaming log files to an external syslog server. You can activate syslog streaming per log file on the LOGS > page. Log Streaming Usability Improvements Quick Links to Service Configuration Pages On the page, you can click the services listed in the section to open their configuration pages.

Barracuda Firewalls can now be reloaded and rebooted if the unit is not activated yet. [BNF-2230] Known Issues High Availability : Manually t riggering an HA failover is only possible on the currently active Barracuda Firewall unit. This issue does not affect automatic failover of HA clusters.
POP3 VNC IMAP4 WebDAV Web forwards (HTTP/HTTPs) All Barracuda Firewall models starting with X200 provide SSL VPN at no additional cost for an unlimited amount of users.
Usability Improvements The following sections describe the usability improvements that are available as of firmware release 6.1.0. Quick Links to Service Configuration Pages On the page, links in the section are now available to provide quick access to the configuration pages of all available services.
Firewall rule entries can quickly be edited after their firewall rule entries are double-clicked. NAT Objects Tab NAT objects are more intuitively integrated into the user interface and can now be found in a dedicated tab. Active Routes User Interface Improvement The window is now consolidated with the network routes configuration window.
Firmware Improvements Enhancement:The DHCP TFTP Host Name field now also accepts IP address and host name combinations. [BNF-2121] Fix: The internal interface assignment of the QoS bandwidth policy Internet now works as expected. [BNF-2072] Fix: Phase 2 settings of IPsec Site-to-Site VPN tunnels are now loaded correctly.
Firmware Improvements Enhancement: It is now possible to disable the SIP Proxy. [BNF-1900] Enhancement: To simplify the firewall rule tester, time settings are no longer available. [BNF-1872] Enhancement: The Active Connections screen now allows performing a Barracuda Labs reputation search for globally routable IP addresses.
DNAT firewall rules can now also be used to perform port address translation (PAT). In the Redirect To field, append the desired port to the IP address. E.g.: 192.168.100.20:8080 [BNF-1582] The default firewall rule LOCALDNSCACHE now also includes TCP port 53 network traffic.
User interface rendering of the recent connection page was slow with huge amount of connection entries. [BTN-1492] The firewall log time filter user interface of the Barracuda Cloud Control was not displayed correctly. [BTN-1462] User objects were not saved correctly.
Log filter for service logs did not work correctly. [BNF-1366] Filtering log files occasionally caused a temporary unavailable message. [BNF-1374] IPsec VPN tunnel status was not displayed correctly. [BNF-1387] Captive Portal was not able to use uploaded certificates.
