sorry did not realise drakconnect was giving problems. I see that presents
a difficulty.

Should be no need to disable in bios. Try
service network stop (as root)
to stop eth0, which should disable its default route. when you stop the
modem and want the lan again
service network start
Of course this is not a permanent fix, just an easier way of disabling the
lan in the meantime.
Alternatively you can use the route command to set and disable all routes.
Again not a permanent fix.

Now on a more permanent basis, without using drakconnect, look in
/etc/sysconfig. There is likely to be a file in there relating to eth0, in
which it should be possible to set an environment variable to tell the box
not to set a default route on eth0 coming up. I am working from an old
version of redhat, which has the same origins as mandrake, but I suspect
there are some changes from what I am looking at. However look for a file
named something like /etc/sysconfig/network-scripts/ifcfg-eth0. On this
redhat box I am looking at that file is read by
/etc/sysconfig/network-scripts/ifup, which in turn has these lines:
# Set a default route.
if [ -z "${GATEWAYDEV}" -o "${GATEWAYDEV}" = "${REALDEVICE}" ]; then
# set up default gateway
if [ -n "${GATEWAY}" -a "`ipcalc --network ${GATEWAY} ${NETMASK}
2>/dev/
null`" = "NETWORK=${NETWORK}" ]; then
ip route add default via ${GATEWAY}
DEFGW=${GATEWAY}
elif [ "${GATEWAYDEV}" = "${DEVICE}" ]; then
ip route add default dev ${REALDEVICE}
fi
fi
I am very poor at reading bash scripts but this seems to tell me that the
setting of a default route is dependent on the settings of the GATEWAYDEV
and REALDEVICE settings in the /etc/sysconfig/network-scripts/ifcfg-eth0
file. Personally I would fiddle with the GATEWAYDEV setting and bring the
eth0 up and down a few times (with the service command as above) and see
if it continues setting the default route. back up the file before you
play with it. And look for differences in the more up to date mandrake
system that you have.
