Just an update after messing around with the Nokia XS-240X-A for a new flat in Punggol.
After logging in via the support page, I thought I had to go through the process of selecting the bridged port in the Network. When the TP-Link HB810 failed to get an IP address, I noticed that modifying the WAN port allowed you to select a "Bridge Mode" instead of "Routing Mode". That allowed me to select Port 1, which was the 10Gbps port. I ticked the VLAN option (set to VLAN 10) and just like that, the HB810 got a WAN address.
(Additional note: All the ports must be in "Routing Mode" before attempting the WAN modification. If one of the ports is already bridged when trying to modify the WAN port, it will show up as greyed out.)
On the HB810, I did have to indicate that it did not have to select VLAN 10 on the WAN port. Once I did that, the WAN instantly connected.
One observation is that while it did issue the router an IPV6 address, it was a /64 address instead of /56. I did some of those online test to check if IPV6 was working, and unfortunately, it reported that it wasn't seeing IPV6 connectivity.
Unfortunately, I forgot to take screenshots. I'll try to do it the next time I'm at the new place.
