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