This guide helps you configure step by step remote access to the UTM using IPsec Internet Protocol Security. IPsec allows you to give individual hosts access to your network through an encrypted IPsec tunnel. The structure is described in the following chart.
First, you configure the UTM to allow remote access. Then, you enable the User Portal of the UTM for the remote access users.
The User Portal offers the Sophos IPsec Client software, the configuration files, the necessary keys, and a configuration guide to the remote access user. You must provide users with their login data for the User Portal.
The Sophos IPsec Client comes with a 30-day trial license. You have to purchase the license to use the unlimited version. The IPsec Client works on Microsoft Windows XP, Vista, and 7 operating systems and will work on Windows 8, too.
