It is possible. If you can receive data from the fileserver, the fileserver can send you callbacks as the ports are the same for both. The question is whether the fileserver will be able to continue to send you callbacks once the data channel has gone idle. This very much depends on the settings in play on the router - you may be able to continue to receive callbacks for anything from minutes to the lifetime of the callback. This is best verified experimentally, rather than people second guessing your router configuration.
