Problems with gateway on LAN

[Andrew <andrew@capital.net.au>]

I have a network of 4 machines.  Two running Debian, one Win98 and one
WinNT.  I have been trying to setup one of the Linux machines as a
masqurading gateway with aliased interfaces.  Currently all 4 machines
are on the same segment of ethernet.

The problem is that with my current configuration, none of the machines
can talk to each other.

The gateway /etc/init.d/network config is:

[snip lo config]

ifconfig eth0 down
ifconfig eth0     192.168.1.1   broadcast 192.168.1.63  netmask
255.255.255.192
ifconfig eth0:64  192.168.1.65  broadcast 192.168.1.127 netmask
255.255.255.192
ifconfig eth0:128 192.168.1.129 broadcast 192.168.1.191 netmask
255.255.255.192
ifconfig eth0:192 192.168.1.193 broadcast 192.168.1.255 netmask
255.255.255.192

route add -net 192.168.1.0   netmask 255.255.255.192 dev eth0
route add -net 192.168.1.64  netmask 255.255.255.192 dev eth0:64
route add -net 192.168.1.128 netmask 255.255.255.192 dev eth0:128
route add -net 192.168.1.192 netmask 255.255.255.192 dev eth0:192

The /etc/init.d/network off the other linux machine is

ifconfig eth0 down
ifconfig eth0 192.168.1.72 broadcast 192.168.1.127 netmask
255.255.255.192

route add -net 192.168.1.64 netmask 255.255.255.192 dev eth0
route add default gw 192.168.1.65 metric 1

I figure if I can get the two Linux boxes talking the others wil work
too, but they can't talk to each other at all ATM.

Is what I'm trying to do possible (with kernel 2.0.36 BTW)?  Is the some
problem with aliased interfaces and IP masq?  Would it work if I had 4
network cards and properly segmented the physical network rather than
just the addresses?
