This chapter provides information on interconnection of headquarters and branch office servers by an encrypted channel (“VPN tunnel”). The following example describes only the basic configuration of a VPN tunnel between two networks. No tips related to access restrictions or other specific settings are included here. For example of a more complex VPN configuration, refer to Kerio Control — Administrator's Guide.
The configuration consists of two parts: settings in the headquarters and settings of the filial. It is supposed that both networks have been already configured as described in chapter 2 Headquarters configuration and that connection to the Internet is available.
