I have a network with firewall. My internal workstations have access ton Internet. I will like to add a sever on the internal network which should not have an access to Internet. Only internal computers should have access to this server. Do I need to setup a second firewall?
I would like to fully isolate server from Internet (both ways). I am using a Linux box as a firewall. Maybe third NIC will solve my problem. My current setup include 3 networks (one is physically isolated from Internet). This works well but each user has two computers (one with connection to Internet (behind firewall) and second one connected only to separate internal server (without Internet). Ideally I will like to have just one workstation per user (with connection to Internet and secure server) but I cannot sacrifice security of my internal server.
