Easy but I made it harder  ;D
by firtst installing win 95 and 2 3com nics
got it all verking and set the adress on nic with soft
ware toke a note of eth addresses on nics
linux usually makes nic with lowest address eth0
other wise  one has to ping to find eth1 which is
the only pingable after floppyfw have started.
eth0 goes to adsl modem
I did the w95 bit if the floppyfw should fail
so I could use analogX proxy instead if needed
(but that is actually bitchier to set up cause of all
email aliases and stuff)
I just hooked it up
configured tcp ip
the msie settings like before as well as e-mail
ftp as http with ftp support.
Cheap can handle at least a hundered clients .
