Kerio Personal Firewall parameters can be set and status information can be viewed in the configuration dialog. Use one of the following methods to enter this dialog:
double-click on the Kerio Personal Firewall icon located on the Systray
right-click on the icon and select the Configuration option in the context menu
Use tabs on the left to switch between individual sections:
Overview — list of active and open ports (see chapter 15.1. Connections and Open Ports Overview), statistics (see chapter 15.2. Statistics), user preferences. (refer to chapter 6.3. Preferences)..
Network Security — rules for network communication of individual applications, packet filtering, trusted area definitions (see chapter 7. Network Security)
System Security — rules for startup of individual applications (read more in chapter 13.2. Application Rules)
Intrusions — configuration of parameters which will be used for detection of known intrusion types (see chapter 11. Network Intrusions Prevention System (NIPS))
Web — Web content rules (URL filter, pop-ups blocking, control over sent data — see chapter 14. Web Content Filtering)
Logs & Alerts — logs viewing and settings (refer to chapter 16. Logs)
Chart at the bottom of the dialog window shows traffic load of a particular network interface. The green bar next to the chart represents current speed of outgoing traffic, whereas the red bar shows current speed of incoming traffic.
Click on the chart to switch between the line graph and the bar graph.
Place the mouse pointer over the chart to view a tooltip giving statistics of network traffic:
speed out (green bar) — current speed of outgoing traffic
speed in (red bar) — current speed of incoming communication
maximum (in+out) — top speed record
minimum (in+out) — bottom speed record
Use the button to block all network traffic (all connections will be stopped immediately). This function can be helpful for example when communication which was supposed to be denied has been permitted by mistake. If this option is used, it is replaced by the option.
If traffic is stopped, this will be shown by the icon and the text below the button.
Note: The Stop all traffic / Enable traffic option is also available from the context menu called through the Kerio Personal Firewall icon displayed on the Systray (refer to chapter 4.2. Icon on the Systray).
Buttons at the dialog bottom provide the following functions:
— saves all changes and closes the configuration dialog
— closes the dialog without saving changes
— saves and applies all changes and leaves the dialog open
Note: Changes in configuration can be done in only tab of one section at a time. If you attempt to switch to another tab or to another section, the system seeks possible changes that could have been made since the last save. If some changes are detected, Kerio Personal Firewall asks users whether they should be saved or canceled.
It is possible to set Kerio Personal Firewall configuration so that it can be accessed only through a password authentication (only authorized users are then allowed to modify settings). In such case unauthorized users are allowed only to view the configuration. Password will be required if a configuration change is attempted.
After insertion of a correct password a particular user will be logged-in. This user will be authorized to change the configuration.
We recommend authorized users to logout after the desirable changes are done so that no unauthorized user can modify the configuration. Use the Logout option in the context menu accessible through the icon in the Systray (see chapter 4.2. Icon on the Systray), or the button in Overview / Preferences. If a user does not log out, the configuration can be accessed and modified unless the Personal Firewall Engine service is closed.
