I own two Deco X60 units. Currently, my mesh network looks like this (ethernet backhaul):

[router] ⇒ [Deco (main)] ⇒ [Deco (satellite)]

This was working fine, except the room where my router is located is being repurposed. I can no longer keep my router and main Deco unit in the same room, which is a problem for connecting the Deco units over ethernet.

Is the below possible, either by configuring my router (Omada ER605) a certain way or by using an intermediary between my router and Deco units?
