Owncloud proxy from readynas



i have found the proxy addon but i do not see a way to install this into the readynas plugin that is inside owncloud.
i need a way for client to be able to access the device from the web and the provider will not let us have a public ip to put the device on the web.
does anyone have any ideas?
basiclly we have 3 outside users that we want to share data with - and its on a readynas.



it might help to explain to which "proxy addon" you're referring.
