Barracuda NG Personal Firewall

9.1 Overview

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