I'm using Apache Guacamole as a gateway.
Apache Guacamole, a free open-source software, offers an efficient, customizable, and affordable solution suitable for budget-conscious users. It is easy to download and set up, providing a quick provisioning system. Users report strong support and recommendation despite some areas like USB redirection and GUI documentation needing enhancement. Issues with networking and lack of advanced features, such as session recording and clipboard functionality, present challenges. Nonetheless, it remains a valuable gateway option.
