The short answer is a Linux box with network cards, routing between the segments. Look up ip_forward, and try searching for the Linux Router Project.I would like to seperate the office from the shop into a different subnet.
The longer answer depends on your goals:
* Are you concerned about overall traffic swamping manufacturing
critical traffic?
* Are you worried about voltages on the manufacturing floor frying
the office LAN?
* Are you afraid that a rogue employee in the office programming the
drilling machine to puncture every metal widget?
* Is the same employee sniffing network traffic to capture CAD/CAM
milling sequences to sell your customers?
* Are your manufacturing employees surfing the web when they should
be soldering, and you want to stop this practice?
Each one of these would indicate different solutions, taking into account your overall budget and knowledge. For instance, I personally would stay away from the flexibilty of VLANs (as seen in another posting) because itcan be quite tricky if you don't work with them frequently.
