Introduction
This manual describes configuration steps to be taken for implementation of Kerio Con-
trol in a model network. This network includes most elements present in a real-life Kerio
Control network — Internet access from the local network, protection against attacks from
the Internet, access to selected services on the LAN from the Internet, user access control,
automatic configuration of clients on the LAN, user authentication in the Active Directory
domain, user browsing behavior control, etc.
Another issue is to provide interconnection of networks between the headquarters and
a branch office by a secure (encrypted) channel (so called VPN tunnel) and secure access of
clients to the local network via the Internet using Kerio Control.
This manual provides guidelines for quick setup. Detailed information addressing individual
Kerio Control features and configuration instructions are provided in the Kerio Control —
Administrator’s Guide available at http://www.kerio.com/firewall/manual.
Network configuration example
Kerio Control configuration will be better understood through an example of a model network
shown at figure 1.1.
