MOVEit Central supports the following HTTP/S proxy server configurations when communicating with any MOVEit DMZ server:
MOVEit Central draws information about whether it should use a proxy server, and the host and port to which it should connect in order to access the proxy server from the Internet Explorer settings of the user under which MOVEit Central runs as a service.
MOVEit Central cannot make use of proxy servers to connect to MOVEit DMZ when it is running as "LocalSystem".
