Thanks a lot.

I could use  Proxy ARP. It's rather  easy and it's
in  the HOWTO.  I  couldn't have  done it  without
tcpdump... Your advice is  quite generic. It reads
: Learn  IP and learn  what the Linux  kernel does
with  your packages  :) And  I know  I need  to do
that.

Is there  a way to  trace the flow of  the packets
inside of  the kernel?  It would  be nice  to have
some  /proc  entry to  watch  that.  I don't  know
whether it exists. I  mean, this packet came here,
and went there ... and so on.
