I have my house wired for 2 separate gigabit Ethernet networks. I want to create one network, let's call it "A" that everyone can get at for backups, AV files, etc. That network would have specific, physically separate hard drives in the Win 7 server. I want to then create a second network, let's call it "B" that is only for SOHO stuff. It too would have physically separate drives in the server. Can I do that? Also, do I need anything special with the dual NIC arrangement? I can use a x1 dual NIC? or get a board with dual NIC's ? And, of course, I have 2 different gigabit switches as well. I am guessing one network would need to be 192.168.1.X and the other 192.168.0.X, which is fine. The main thing I want to do is make sure that the hard drives assigned to network A can't be read or altered by network B, and vice-versa. As a matter of fact, I don't want A drives shares visible on the B network, or vice versa. What do I need to do in terms of IP range, static or DHCP, subnets, drive assigning, etc? I've never tried something like this before. I don't want to do something like give drive shares different passwords because all that does is create "forbidden fruit" and such. If the drives are never seen, they are never wondered about. Thanks for any thoughts.
