yes, this is because by default Cloud is selected for DSL connection > see selection under Ether port page.
By default you have 1 Ethernet6 port and by default it is selected for DSL connection. Change Ethernet 6 connection port to be Coax under Ethernet6 page. Then, you can add new Ethernet 6 to Coax connection.
OR add another Ethernet port or Gig port to the cloud. then you have to go to that new GIG or Ethernet page and select Coax.
