Trouble with multiple ethernet cards

Running Red Hat 9 kernel 2.4.20

Here's my configuration:
3 Ethernet cards, all the same, with a Myson chipset
eth0 for my adsl modem
eth1 for client 1
eth2 for client 2

The ip addresses are:
eth0: 10.0.0.150
eth1: 192.168.0.1
eth2: 192.168.0.3

all cards have their subnet to 255.255.255.0


+---+----------->client1
adsl-> |box|
+---+----------->client2

Here comes the problem, I can only connect to one of my clients, pings
result in network unreachable if i try the other one, and it depends on
which interface goes up first.

If set the the ip's to 192.168.0.1 and 192.168.1.1 for testing and it
worked, apperantly they just won't work if they are in the same subnet.

Does anyone know why this is? It looks really weird to me, maybe linux uses
the wrong interface, so it tries to ping on eth2 when it needs client 1 or
otherwise.

Thanks in advance,

Robert

No, it won't. How is it supposed to know which one to use? It appears to
be doing the best it can and using the first to come up.

Put them in different subnets or invest a few euros in a small switch.
