OK I need some input. A relation has a Dell desktop that will get connected to a Unix server with W2K. He wants to put another nic in to connect to a Mux type setup with a modem. They've done it with a single nic in a seperate desktop. What they want to do is put both nics in the Dell, but neither nic can communicate with each other at anytime. They're putting a Cisco switch on the network soon. Would programing the port to only accept packets for that specific IP work or will the other nic still be able to pass back and forth. You may need more info and I'll pass what I can.
