I have an existing network comprised of office user computers and production computers/PLC's on the same subnet. My goal is to isolate the office machines and put them on a separate subnet as to not be subjected to all the data collection bandwidth usage from the production equipment. My network is setup as 192.168.1.1 - 254, subnet 255.255.255.0. I want to keep the production equipment untouched as most are static IP's, but the office users are DHCP so would like to setup new subnet for them. My question is; what new IP schema should I use for my office environment, ie: 192.168.0.1 - 254 subnet 255.255.254.0? Also, the new router that I have to buy to make this happen, what IP forwarding to the old router do I need to do to make this seamless so my users can still see the production equipment? And lastly, I obviously have to change the DHCP scope range on the server to hand out the new IP's. (thats not really a question, just thinkin' out loud). Any help or input is greatly appreciated.
