I recently experienced a similar situation when trying to setup a virtual host that would proxy requests to another http server while the Apache httpd daemon also honored my mod_rewrite rules for blacklisted sources which should not be proxied. It took me several hours to figure out how to configure Apache httpd to do what I wanted. Nonetheless, your description of the situation is incoherent. Let us start with your last paragraph where you say "If I go straight to localhost:2000". I assume you are saying that if you enter " http://localhost:2000/"; in your web browser you get the expected behavior. Is your Apache web server listening on port 2000? The reason I ask that question is due to your statement that "any requests the app makes are sent to localhost:2000". Which implies the app in question is directly connecting to the backend without being proxied by the Apache httpd process. What is this "app" and is it connecting to port 2000 or port 80 on the local host? What is the "app" in the statement "any requests the app makes"? Is it a web browser or something else? And if something else please provide more details. What do you mean by "the remote IP address is shown as localhost:80"? Shown where?
