Q: How to force screen sharing to use Ethernet port 2?

I have 3 MacPros connected in my studio. MP1 is the master and I use Screen Share to see MP2 and MP3. Now I have bought a very fast switch to connect those 3 with each other via the Ethernet Port 2 on MP1 and at the same time have the MP1 connected to the internet and printers, servers and so on via Ethernet Port 1. But that is not possible, because Screen Share will prefer to use the port where the internet/router is connected.

When ONLY Ethernet Port 2 is active, screen share is using this port and it works perfect, but the moment I activate Ethernet Port 1 again, the 2 remote macs looses connection.

Is there a way to force Screen Share to use the Ethernet Port 2?

Mac Pro, OS X El Capitan (10.11.5), 12 core, 48 Gb. ram

Hi
I think you were very helpful to answer, but unfortunately it didn't solved my problem.
The Screen Share app built into Mac Os is not that easy to control. Furthermore I also need to direct VEPro which is a audio app to use the 2. port, and I can't get any information how to do that, so I give in!
