Dear Jason,
many thanks for your answer!
Sorry that I didn't explain as clear as necessary what I want to
do and in what kind of environment I'm working in. So, here some
precisions:

I agree with you that an IP address is assigned to an interface and not to
a computer. The problem now is, that I have three interfaces, but only
two IP addresses (belonging to the adress space of the C class network
of our institute). As I am not the administrator for the institute's network
I cannot assign myself an IP address :-(
And I think our admin will not be happy to "waste" an IP address for an
interface that only will connect to PCs together.

To do this, I need a third IP address. Should this be an C class address from
the institutes network or any address from the reserved address space,
say 192.68.10.0 ?

The LAN is the institute's network and in my lab I only have one ethernet
plug in the wall but two computers that I want to connect to the LAN.
The easiest thing would be to buy a small hub and plug the two computers into
the hub. But as I have a second ethernet card in one of the two computers
I thought it should be possible to use this one as kind of a hub/repeater/bridge
to connect the second computer to the LAN:
_
| aaa.bbb.ccc.76(eth0) aaa.bbb.ccc.34
| ___________ ________
| | | | |
|----|eth0 eth1|-----------|ethO | eth1 has no unique IP address
| |__________| |_______| assigned to it
|
|
institutes LAN, aaa.bbb.ccc.0
I hope it is clearer now and that you have an idea what I'm missing.
Many thanks for your help :-)
