Rsync over SSH on consumer-grade ReadyNAS

Thanks blumman! I purchased the add-on as well and I've so far not gotten it to work. But an added wrinkle, which I suspect is the cause, is that I need to use a port other than the default port 22 for SSH. My guess is the code that enables SSH defaults to port 22 and there's no override. (I've updated the sshd_config file to specify the SSH port and I can therefore access the NAS via SSH. But rsync over SSH isn't working when activated via Frontview.)

Do anyone have any ideas if/how I can update the SSH port for this? I've looked for a way to ask for support for the add-on on readynasxtras.com but there doesn't appear to be anywhere to do so...
