Barracuda Web Security Service

Redirecting Traffic Using Proxy Options

  • Last updated on
The quickest and easiest way to deploy the Barracuda Web Security Service is to direct web traffic from your network to the Barracuda Web Security Service, a cloud-based solution, for policy enforcement. Using existing network elements such as browsers, a network proxy, or your Barracuda (NG) Firewall, you can forward web traffic to the Barracuda Web Security Service and apply a single set of web use rules to all web traffic. This configuration option works well when you don’t need to distinguish between various users or groups to enforce rules or generate reports. If you do need to distinguish between traffic based on users and groups for enforcement and reporting, you will need to deploy a Barracuda Web Security Gateway appliance.

 The Barracuda Web Security Service currently supports IPv4 (only) for web traffic for filtering and reporting.

Direct Proxy Deployments

There are three methods for configuring direct proxies from your network to the Barracuda Web Security Service:

Direct from a Web Browser Proxy

In this mode, you configure your users’ web browsers to direct traffic to the Barracuda Web Security Service. You can use any method of managing proxy settings, but the simplest way is to configure your web browser connection settings for an upstream HTTP proxy on port 8080. You must have the Service Host URL that appears on the Support tab of the Barracuda Web Security Service Manager. Deploying the Barracuda Web Security Service as a direct proxy requires you to configure your firewall to allow internal clients to access the Barracuda Web Security Service on ports 8080. For instructions, see How to Manually Configure Proxy Settings.
