I have several devices on and connected at all times to the blue curve router. When I try to forward a port through its restricted interface, it only allows listing of connected devices by computer name rather than by IP address like every router in the world.  The issue that I am having is that it is not listing three computer names on the network even though those computers are online with an ethernet connection. Phoned support today, gave the the computer names, IP address and MAC and they couldn't figure it out. In the end they said that this is beyond their scope of service.

Anyone has any ideas how to view the connected devices by IP or how to get bluecurve to see these three computers that are connected to it?
