Protection against network attacks 155
To change a zone’s status, or to enable/disable Stealth Mode, select the zone
from the list, and use the appropriate links in the Rule Description box below
the list. You can perform similar tasks and edit addresses and subnet masks in
the Zone settings window, which you can open by clicking Edit.
You can add a new zone to the list while viewing it. To do so, click Refresh.
Firewall will search for potential zones to register, and if any are detected, the
program will ask you to select a status for them. In addition, you can add new
zones to the list manually (for example, if you connect your laptop to a new
network). To do so, use the Add button and fill in the necessary information in
the Zone Settings window.
To delete a network from the list, select it in the list and click on the Delete
button.
12.1.1.7. Firewall Mode
The Firewall mode (cf. Figure 54) controls Firewall compatibility with programs
that establish multiple network connections, and to network games.
Maximum compatibility – the Firewall ensures that Firewall will work optimally
with programs that establish multiple network connections, for example, filesharing
network clients. However, this mode may lead to slow reaction time
in network games. If you encounter such problems, you are advised to use
High Speed.
Maximum speed – the Firewall ensures the best possible reaction time during
network games. However, file-sharing network clients and other network
applications may experience conflicts with this mode. To solve the problem,
disable Stealth Mode.
To select a Firewall mode:
1. Open the application settings window and select Firewall under
Protection.
2. Click on Settings under Enable Filtration System (cf. Figure 47).
3. Select the Additional tab in the Settings: Firewall window and
configure Maximum Compatibility or Maximum Speed.
Changes to the Firewall settings will not take effect until after Firewall has been
restarted.
