Once you do that, you can choose between enabling the IPsec VPN protocol (you can get more info about that here) or use the proprietary Kerio VPN protocol only. To configure it you can refer to the official documentation. Among the various services offered, Kerio Control also includes a proprietary VPN implementation called Kerio VPN, accessible through a proprietary VPN client called Kerio Control VPN Client.

If you're a Network Administrator you'll have most likely heard of Kerio Control, an excellent Firewall, Router and Leading-Edge IPS solution developed and mantained by Kerio, Inc (we already mentioned it here).
