I have an extra ethernet card I would like to place in my office
machine and use to (sometimes) connect my laptop:

      laptop          desktop
      ------          -------
      e-net card ---> e-net card 2
                      e-net card 1 ---> office net/world

1.  Is this feasible?

2.  My laptop and desktop machines have IP addresses.  Do I need a new
    (legitimate) one for the second card, or can I use one of the 
    "private" addresses since no one should need to address card2 from
    anywhere outside of my office?  

3.  How do I tell card2 to send what it gets out on card1?

4.  How do I tell card1 to accept stuff addressed to the laptop and
    forward it along to card2?

5.  Are there any handy scripts for switching between configurations
    of laptops?

I've been working through the O'Reilly TCP/IP Network Administration
book, but I'm not sure what to do.  Suggestions or pointers to other
references would be gratefully accepted.

Thanks-

Russ Murphy
