Crashplan Rockon Network listen address

I’ve just set up the Crashplan rockon and tried to back up to it from another computer on my lan. Problem is that When you select the computer from the Crashplan gui on the computer to back up the network address is detected as the Docker address. I’ve had my reservations in setting up of Rockons due to the inability to add a real ip address to a rockon. This is clearly a major roadblock. It seems a glaring omission to not have included this. I’ve been determined to use a Linux based system but I feel that I will have to use Freenas instead if this isn’t on the roadmap soon.
