OK, this is not really a Linux related post, but OS independent
networking. If that bothers you, stop reading.
For anyone who is still interested, here is my situation. My company
will be installing a new industrial control panel at a municipal water
treatment plant. The panel will have several components (PLC, HMI, AC
motor drives, etc.) connected via ethernet. The panel will also contain
a fully managed ethernet switch with DHCP and VLAN capabilities
For obvious reasons, the folks at the plant do not want this panel to
take 5+ IP address from the top level network, so they've asked that
this panel be configured as a subnet. For example, if the primary
network uses IP addresses 192.168.1.x, the devices in this panel should
be addressed 192.168.2.X, and be accessible to 192.168.1.X devices.
I've set up quite a few (BASIC) home networks, and this task doesn't
really seem like it should be that hard. Also, I've read quite a few
articles explaining the binary aspects of IP addresses and how subnet
masks work, but its not really sinking in. Can somebody point me in the
direction of a practical walkthrough showing how this can be
accomplished? I don;t need anything hardware specifiec, but something
with screenshots and actual device settings would be very helpful.
