This guide describes step by step the configuration of a remote access to the UTM by using L2TP over IPsec. L2TP over IPsec is a combination of the Layer 2 Tunneling Protocol and of the IPsec standard protocol. L2TP over IPsec allows you, while providing the same functions as PPTP, to give individual hosts access to your network through an encrypted IPsec tunnel. The structure is described in the following chart. On Microsoft Windows systems, L2TP over IPsec is easy to set-up, and requires no special client software.

To configure and establish L2TP remote access connections, do as follows:

  1. Create a user or user group to use remote access.
  2. Configure the L2TP remote access connection in the UTM.
  3. Provide users with the Sophos Connect client and configuration files.

    There are two methods:

    • Enable the UTM User Portal for the remote access users to download the installer and configuration files.

    • Send the installer and configuration file to users.

The User Portal offers the necessary keys and a configuration guide to the remote access user. You must provide users with their login credentials for the User Portal.
