Internet Connection 6.2 Connection with a single leased link - dial on demand If the Kerio Control host is connected to the Internet via dial-up, Kerio Control can automatically dial the connection when users attempt to access the Internet. Kerio Control provides the following options of dialing/hanging control: • Line is dialed when a request from the local network is received. This function is called Dial on demand. For further description see below. • Line is disconnected automatically if idle for a certain period (no data is transmitted in both directions). • Maintenance of persistent connection or disconnection of the link within defined time ranges. Requirements The corresponding device must be installed on the Kerio Control (usually an analog or an ISDN modem) and the corresponding dial-up connection must be created in the operating system. It is not necessary to define and save login data in the dial-up settings, this information can be defined directly in Kerio Control. This connection type also requires one or more network cards for connection of individual segments of the LAN. Default gateway must NOT be set on any of these cards! We recommend you to create and test a dial-up connection before installing Kerio Control. Warning: Before configuring the LAN and the firewall for a Internet link dialed on demand, please pay special attention to the information provided in chapter 25.5. Correct configuration of the network with respect to specific qualities and behavior of on demand dial helps to avoid subsequent problems. Configuration with the wizard On the second page of the Traffic Policy Wizard (see chapter 7.1), select A Single Internet Link — Dial on Demand. On the third page of the wizard, select a corresponding dial-up connection (Internet link). If authentication data are not saved in the operating system, username and password are required. In the Software Appliance / VMware Virtual Appliance edition, the wizard allows: 64
