Ubiquiti Dream Machine (UDM) – unable to connect to NBN

I don’t want the NBN ISP router running anymore and use Ubiquiti Dream Machine (UDM) instead. But when I try to remove ISP Router it and direct connect UDM to NBN, the connection fails. Ubiquiti Dream Machine (UDM) - unable to connect to Internet

UDM is set for DHCP, only other options are PPOE (which requires credentials) and Static IP (I have a dynamic IP).

ISP router the connection mode says “IPoE routed mode”. I don’t have to enter any credentials.


  1. WAN connection – DHCP, no VLAN tagging
  2. Turn off NCD for at least 30 minutes to reset the DHCP settings, then connect the UDM.
