Hi.
I've been tasked with setting-up a POS (Point-of-Sale) system for a small restaurant. The POS will consist of 5 terminals and a server (all WinXP-Pro), all networked together.
I would like to completely isolate the 5 terminals from the Internet. Also I would like to allow only very limited Internet access to/from the server, 1) for credit card authorization and 2) for remote access (e.g. RAdmin).
I am thinking that one way to accomplish this would be to have a "local" switch connecting all 5 terminals and the server, thereby securing the terminals. Then I would install a second NIC in the server and have it connected to an "Internet facing" switch connected to a router (connected to a DSL modem). I would then use the router's firewall to block all traffic to the server except those aforementioned.
A) Would this work? If so, are there any particular features my router would need, or can they all do this?
B) Is there a better / easier way to accomplish my goal, perhaps without needing the extra switch and NIC?
Please be gentle, this level of networking is mostly new to me. Thanks!
