This question pertains to a situation where we have a server with a single NIC somewhere on a large corporate network. (Not sure how much it matters but in this scenario there are no VPNs involved.)
We also have two sets of users, SET A accessing the server from IP addresses within a specific range, and SET B accessing it from IP addresses within another range.
Is it possible to make the server accessible through one IP-address for SET A and another for SET B? What are the requirements (limitations) for this to work?
