And do 1:1 Port Aware NAT translation. Plugging into the spare port on PLC comm coprocessor. They’re L18s or whatever so no extra network card. Right? The server lives at: 120.120.80.212 For example: Port 1 --\> 192.168.0.100:44818 --\> 120.120.80.1 \<–\> Server Port 2 --\> 192.168.0.100:44818 --\> 120.120.80.2 \<–\> Server I have a coupl…

I plan on updating this post. With a guide of sorts.

With what I, as a very novice network/IT eng, did when I was in your situation.

But, basically you need to set up a network device to isolate ports from each other. And NAT 1:1 translate packets between devices and server.

Or you could use a device for every machine. Like with what was mentioned above. With Stratix switches or something. If $$$ isn't an issue. I'd go that way.
