What's New in Barracuda NextGen Firewall X-Series Version 6.8.0.007

Safe Search

Protect users behind a Barracuda NextGen Firewall X-Series from undesired content in search results by enabling Safe Search for the access rules handling web traffic. No configuration is required on the clients. The necessary parameters are automatically appended to the URL when the request is forwarded by the X-Series Firewall. Safe Search is supported for Google, Bing, and Yahoo search engines.

For more information, see How to Enforce SafeSearch in the Firewall.

YouTube For Schools

The Barracuda NextGen Firewall X-Series can transparently add YouTube for Schools restrictions for all connections the X-Series Firewall forwards to YouTube without the need to configure the clients. YouTube for Schools is configured directly in the access rules matching HTTP and HTTPS traffic connecting to YouTube.

For more information, see How to Enforce YouTube for Schools in the Firewall.

Custom Block Pages

virus_scanning_block_page_eicar.png

You can customize the block pages for Virus Scanner, URL Filter, Application Control, and SSL Inspection. Each page has a predefined list of placeholder objects that are replaced on-the-fly by the Barracuda NextGen Firewall X-Series when the block page is delivered to the client. HTTP connections blocked by a Block or Reset access rule can be redirected to an HTTP block page.

For more information, see Custom Block Pages.

Transparent Redirection

Transparent_Redirect.png

The Barracuda NextGen Firewall X-Series can transparently redirect all HTTP and HTTPS traffic to a Barracuda Web Filter or any other HTTP or HTTPS processing device. The Web Filter can then process the HTTP/HTTPS request using the original source and destination IP addresses. This allows the Web Filter to create meaningful statistics and connection information.

For more information, see How to Configure a Transparent Redirection to a Barracuda Web Security Gateway.

URL Filter Improvements

url_policy_warn_RN.png

For more information, see Schedule Objects.

Known Issues and Limitations for 6.8
  • After saving an access rule or application policy for which you used the inline Create New feature, you must reload the page twice for the rule or policy to be displayed in the ruleset.
  • The Barracuda NextGen Firewall X-Series is designed to be used with a display resolution of 1280x1024 or higher. Use the browser zoom function to use the management interface on screens with a lower resolution.
  • When editing an access rule on a screen with a resolution of less than 1280x1024, the browser zoom function must be used to view the entire pop-over.

  • Safe Search cannot be enforced on Google Chrome browsers using the experimental QUIC protocol. Blocking UDP port 80 and 443 for clients using Google Chrome resolves this issue.
  • Smaller Barracuda NextGen Firewall X-Series models may take up to 10 minutes to verify the update package causing a browser timeout. Log in again to apply the update.

  • The SIP proxy cannot be used for external Barracuda Phone appliances. Use access rules to open the necessary ports instead.

  • If appending a port to the first target IP address of a DNAT access rule, the port is applied to all target IP addresses.

  • Barracuda NextGen Report Creator is only available for Windows 7, 8, and 8.1.

  • Inline editing or creation of connection objects is not possible for application-based connection objects.

  • Application-based connection objects cannot be renamed.
