4.2 Network

The Personal firewall controls all network traffic to and from the system. This is accomplished by allowing or denying

individual network connections based on specified filtering rules. It provides protection against attacks from remote

computers and enables blocking of some services. It also provides antivirus protection for HTTP, POP3 and IMAP

protocols. This functionality represents a very important element of computer security.

Personal firewall configuration can be found in the Setup pane after clicking on the Network title. Here, you can adjust

the filtering mode, rules and detailed settings. You can also access more detailed settings of the program from here.

The only option for blocking all network traffic is to click Block all network traffic: disconnect network. All inbound

and outbound communication will be blocked by the Personal firewall. Use this option only if you suspect critical

security risks requiring the system to be disconnected from the network.

The Disable filtering: allow all traffic option is the opposite of blocking all network traffic. If selected, all Personal

firewall filtering options are turned off and all incoming and outgoing connections are permitted. It has the same effect

as no firewall being present. While Network traffic filtering is in Blocking state, the Switch to filtering mode option

enables the firewall.

The following options are available when Automatic filtering mode is enabled:

Automatic filtering mode – To change the filtering mode, click the Switch to interactive filtering mode option.

Zone setup... – Displays the trusted zone setup options.

The following options are available when Interactive filtering mode is enabled:

Interactive filtering mode – To change the filtering mode, click either Switch to automatic filtering mode or

Switch to automatic filtering mode with exceptions depending on the current filtering mode.

Configure rules and zones... – Opens the Zone and rule setup window, which allows you to define how the firewall

will handle network communication.

Change the protection mode of your computer in the network... – This allows you to choose between strict or

allowed protection mode.

Advanced Personal firewall setup... – Allows you to access the advanced firewall setup options.
