I’m thinking about adding a third Ethernet port to my MacPro7,1 (2019) via an Apple Thunderbolt to Gigabit Ethernet Adapter.

Current setup:
Since Eucon defaults to Ethernet port 1 on Mac I use that at the moment.
I have a switch on port 2 dedicated to VEPro servers. (I don’t want to mix internet and VEPro servers on the same switch)

Will it work with a third Ethernet port connected via TB for internet access with this setup?

And in that case - is it possible to use a second, dedicated, switch to connect multiple computers to the internet, or do I have to use a router for that?

As for now I use Wi-Fi as my third interface in Network Setup (macOS) to go on-line.
I’d like to turn that off if I can use ethernet cables for the web, but I guess I’ll have to keep using Wi-Fi to connect my iPad (Avid Control) to EuControl, if it’s not possible to use Bluetooth for that.

Appreciate any thoughts!
