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