E400 or 500 AP's behind an internet proxy server

I am looking to deploy several E400 or 500 AP's behind an internet proxy server, I still need them to be visible via CNmaestro but i cant see the setting for this on the  AP gui.

Is this possible?    

Thanks 

no, APs being behind a proxy server is currently not supported. It will be supported in a future release, but we dont have a commited timeline yet.
