If the Advanced mode of the firewall is selected as default during the installation (see chapter 2.2. Initial Configuration), the Kerio Personal Firewall automatically detects active network interfaces of the computer it is installed on. Upon each new interface detected, the user will be asked whether the interface is connected to a trustworthy network.
Note: Trustworthy network is a network computers of which are considered as secure by a user. Typically, it is a local network which is protected from internet attacks by a network firewall. Kerio Personal Firewall enables definition of various specific actions for trustworthy networks and other for the rest of the Internet (for details, see chapter 7.4. Trusted Area).
The Name entry is specified by a name of a corresponding network adapter. The Address item provides information of IP address of this adapter and the mask of the network which it is connected to. Name of the interface can be edited (it is recommended to provide a short and apt description, e.g. Network card, Internet line, etc.). ID of the adapter detected at the corresponding controller is used as the name by default.
By clicking the button, the subnet to which the interface is connected will be added to the group of trustworthy IP addresses (Trusted area). If is clicked, the network will be considered as a part of the Internet.
Notes:
Anytime, group of trustworthy IP addresses can be edited (for detailed information, refer to chapter 7.4. Trusted Area).
Whenever any other interface is added or enabled or an interface is connected to a new subnet, Kerio Personal Firewall detects it and the New network interface dialog is opened.
As to dial-ups, the telephone number which is being dialed is displayed. User can enable or disable this connection.
Kerio Personal Firewall finds out whether the telephone number has been changed since the dial-up was dialed the last time (this protects users from undesirable change of dial-up configuration). For details, refer to chapter 7.8. Checking of dialed telephone numbers.
