Please refer to attached diagram "Network [url removed, login to view]"
Machines 1,2,3,4 are on their own network (201.1.1.x). They are connected through an ethernet switch, which is connected to a router (#1) that controls a LAN in the 201.1.1.x range.
Control PC #1 is also connected to that router to interact with machines 1-4.
So far, this works fine.
Router #1 is connected to router #2, the main network router. Router #2 controls a LAN in the 192.168.2.x range. Control PC#2, which has a 192.168.2.x IP, can connect to the internet just fine.
I want control PC#2 to be able to interact with machines 1-4, while still keeping its internet connection and [url removed, login to view] IP.
Also I want control PC#1 to be able to access the internet, while still being able to interact with machines 1-4.
How do I configure the routers/PCs to set this up?
