Serv-U Gateway is a secure addition to Serv-U MFT Server and Serv-U FTP Server. It allows you to safely accept incoming connections in the DMZ, and provides deeper protection for file transfers on secure networks. Gateway plays a similar role to that of a reverse proxy server. It safely handles traffic that should not be directly passed from the Internet to secure internal systems. A two-tier deployment involving Serv-U and Serv-U Gateway satisfies most “managed file transfer” requirements.
