Introduction

This guide helps you configure step by step remote access to Sophos UTM using the Secure Sockets Layer (SSL) protocol. SSL remote access in UTM provides security by a double authentication using X.509 certificates, and username and password. It uses the TCP port 443 to establish an encrypted tunnel to your organization, giving your users access to internal resources.

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 free Sophos SSL VPN Client software for Windows, including the configuration, the necessary keys, and a configuration guide for remote access users. Users of other operating systems, such as Linux or macOS, can download configuration files for their operating systems. Android and iOS users find a download link for the OpenVPN app.

You must provide users with their login data for the User Portal.
