I don't know a lot about these types of devices, but in general, when accessing services on my local network from an outside IP there is usually a twin requirement that first all required ports are being correctly forwarded by your router, and secondly that any device specific configuration is correct, i.e. are there any options to turn on 'remote access' or something similar. If this fails, could you put the device in your DMZ?
