I use Qobuz and Roon, and I currently use an iMac which has Roon Core installed on it.
I use a Lumin T1 streamer
Everything is connected conventionally through a router and a switch.
However, I am currently building a fanless PC, which will have dual ethernet sockets on it.
I wondered therefore if the following will work:
Connect the Lumin T1 direct to the second ethernet connection on the fanless PC.
See diagram of both current and proposed systems. (only network connections are shown)
I presume that I MAY need to use a crossover cable between the Lumin and the PC, and have network sharing turned on. (crossover cables are usually used to allow the ethernet ports of two computers to be connected directly, to share data and internet connections)
