I am currently working with 2 seperate private networks that do not connect in anyway and with two separate addresses.
Network A IP: 172.16.5.X
mask: 255.255.255.0
Network B IP: 192.168.65.X
mask: 255.255.255.0
Network A connects to a cisco router that handles the internet connection. Thus all equipments on Network A have net access. Now I want to put a windows server 2003 between the router and networks A and B. Since the router belongs to our ISP I cannot reconfigure it, So I am thinking about using 3 nic cards on the server. One each connecting to the switches for networks A and B whiles the last one connects to the internet via the router. I am thinking that if this is possible, I can then go ahead to use ISA server for firewall… any helps and guides?
