Chapter 4
Interconnection of the headquarters and branch of-
fices
This chapter provides information on interconnection of headquarters and branch office
servers by an encrypted channel (“VPN tunnel”). The following example describes only the ba-
sic 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 the Kerio WinRoute Firewall — User Guide document.
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 and
that connection to the Internet is available.
