I don't believe it is possible to do that in the manner you're suggesting. What is your purpose for using two ethernet cards with two different IP's on the same network? The carrying capacity of your switching fabric (hub or switch) as well as the ethernet card on the host you try to communicate will limit your bandwidth, so you will not see any performance gain from using the 2nd ethernet card, even if you setup an effective method of load balancing. If you want to use your freebsd box as your switching fabric however, you can setup the 2 cards as a bridge. "man 4 bridge" will explain how to do that. You would then only need 1 IP address for your bridge interface, and you can add a 2nd IP using aliasing as well if you wish. Keep in mind that this will be more cpu intensive than just setting up a separate network on each card, although if your machine is relatively fast, the difference will be negligible. I hope this helps. If not, perhaps you could explain more about what you are trying to accomplish, which will enable us to help you better.
