Can I create 2 internal zones on one ISA server and seperate them from each other? I have a small customer with one ISA server. They have two seperate departments located at the same place. They should not have access to each other, but both need internet access. Can I do this with several nettwork cards on one ISA. With larger customers, we sometimes need a lot of segments, and would need even more inernal zones - do ISA support this?
