This is an odd set up. I have a machine on a LAN that acts as one of two terminals for this certain network program. I have an extra identical machine, with same size hard drive. I would like to place a switching router assigned to this terminals external IP in terminals place. I would then like to clone the hard drive of that terminal, place the clone in the extra machine, and attach both to the switching router. the functionality I would like to achieve is thus, I want the server to see the router, now assigned the terminal's original address, as just one machine, so any data it sends out is essentially then split and sent to both machines simultaneously, and then any data sent from one of the machines would be sent to the server. I would, if this set up is possible, end up with a server controlling what it believes to be two terminals, and would actually have three terminals operating, two of which appearing as one. I know I could accomplish this if I had had thousands of dollars to spend on expensive networking equipment, but I would like to use an inexpensive option. Is this set up possible, and what switch/router would be best to use?
