Need to have 2 separate networks with 1 ISP connection
We have a very basic workgroup network run by a Netgear FVS318. The proprietary software we use runs an SQL database and only one of these databases can run on a network at at time. The problem is we need to run another instance of the software and database concurrently and independent of each other but the software will not allow it.
I need to "split" the network into 2 separate networks where one group of computers cannot see each other while being able to keep the current router if at all possible. We do have a windows 2003 enterprise server that is not being used to its potential at all. DHCP is on the router. Any ideas on what would be the easiest way to accomplish this?
