We have a scenario where the customer wants the control network (PLC, HMIs) and their business network separated. Has anyone ever taken the path of installing two NICs into the server. Say for example one NIC is set to 192.168.1.200 and the other one is set to 172.16.2.200 or something else. Can the clients on the control side (192.168 range) access the gateway and launch clients at the same time as the office side (172.16)? Is there any other network administration to do? I guess the other option would be to have a router between the control network and the office network and then just forward the ports.
What are your thoughts?
