Network Card Strangeness



All,

I have four network cards in an FC2 machine.  This machine is supposed
to act as a system router between different segments of a LAN, some of
which is Windows, most of which is Linux, some 10baseT and some 100baseT:

   eth0: NC100 Network Everywhere Fast Ethernet 10/100 -- a PCI card
         Manuf: Linksys    Driver: tulip

   eth1: NC100 Network Everywhere Fast Ethernet 10/100 -- a PCI card
         Manuf: Linksys    Driver: tulip

   eth2: NC100 Network Everywhere Fast Ethernet 10/100 -- a PCI card
         Manuf: Linksys    Driver: tulip

   eth3: 3c940 10/100/1000Base-T [Marvell]             -- on motherboard
         Manuf: 3Com Corp  Driver: sk98lin

In the System Services->Network control panel, all three devices appear
and can be activated.  They then stay active until reboot or network
restart, but I can't seem to get a 'ping' to work through eth1 or eth2
even if I use 'route' to make them the default.  'ifconfig' shows them
all present with their (different or same, it doesn't seem to make any
difference) IP addresses and 'route' shows almost the correct segment
routing, except that they all have 192.168.1.0 on them which I don't
want.

Regardless of the active/inactive state in the control panel, on boot or
network restart, only eth0 and eth3 are started.  Why is this ?

I am trying to get to:

   eth0: host IP 192.168.1.64, route: default
   eth1: host IP 192.168.1.64, route: 192.168.1.63 only
   eth2: host IP 192.168.1.64, route: 192.168.1.32 only
   eth3: host IP 192.168.1.64, route: 192.168.1.100 only

Any ideas how can I get there ?

Jonathan
