Barracuda NG Personal Firewall

9.1Overview

The Barracuda NG Personal Firewall is a lighter version of the Barracuda NG Firewall especially designed for client usage. Nevertheless, most configuration options of the Barracuda NG Firewall are available. When connected to an Access Control Service or via VPN, the Barracuda NG Personal Firewall can accept rule sets sent from the Barracuda NG Firewall (depending on the used client license).

Open the configuration mode of the Barracuda NG Personal Firewall by right-clicking (VPN status) in the system tray and selecting NG Personal Firewall from the context menu or by browsing to Start

>All Programs > Barracuda NG Network Access Client > NG Firewall.

Selection between the following functional firewall modes is available in the context menu of the system tray icon:

•Block All

•Barracuda Networks Secure Mode

•Disable Firewall (Allow all Traffic)

The active operational mode is selected. To change the mode, click another item in the menu.

DO NOT directly switch from Disable Firewall (Allow all Traffic) to Block All. Always select Barracuda Networks Secure Mode as intermediate step.

Each rule in a Barracuda NG Personal Firewall rule set is constructed from a variety of configuration entities (Adapters, Networks, Services, Applications, Users), which can be created and maintained independently from the rule set itself. They are then pieced together building a logical formation. Each configuration entity may be accessed from the Configuration sub-menu in the left navigation bar.

The Configuration section of the Barracuda NG Personal Firewall complements the automatic configuration mechanisms made available by the Firewall Settings Wizard in the Administration section (9.9 Administration - Firewall Settings Wizard, page 120). It allows you to:

•Create rules from scratch in the Rules view (9.8.2 Rules, page 104).

•Modify objects and rules that have been created automatically determined through settings in the Administration view (9.9 Administration - Firewall Settings Wizard, page 120).
