We have an enterprise network with several process control systems.
Each process control system has its own network of controllers. Through the enterprise network there is access only between servers.
The task is to connect to the controller from another server (red arrow in the diagram)

How can I solve this issue?

Configure routing on the server on the left, and on the server on the right, configure the route to the network 192.168.1.0/24 through the server on the left

1. If OpenVPN, then we use push subnets behind clients. ( link )
2. If something else, then turn on forwarding on the left server, do masquerading of the right subnet to the internal interface, route the left subnet 192.168.1.0/24 through this server
3. If on both sides there are normal machines as vpn clients - gre tunneling
