Pretty simple setup i have using a draytek router upgrading to a ER8411

WAN 1 PPPOE with a /29 subnet, pppoe assigns 1st ip in range and use the wan alias on the draytek to use the range, unifi has same option on the dream machine and other routers

soon as i select pppoe on the connection the wan alias goes, only thing i can see is "secondary connection" but what im wanting to do is not a secondry connection.

am i missing something?

this is not anything extravagant i want to archive, also tried it through oc200 managed as well
