I'd suggest creating your own fakenet and run ipfw/natd to alias it to the outside world, unless your office will let you have your own ip. > 3. How do I tell card2 to send what it gets out on card1?

Routing. natd will actually block that traffic unless it's part of an established connection, at which point it'll do the necessary translations. > 5.
