I am looking for a software firewall to install on servers. I need to get each server to have only one port opend on one network card, and all ports opened on the other network card. here is a link to an image that shows the network layout:
you will notice the Red Cables, going to a Gigabit Switch, and that should only be for backups, but it will open the network if I will not have a softeware firewall installed on those servers.
is there a software that I can install on a server, which will give me a control over the traffic to either one of the network cards?
thanks a experts.
