you can't use 2 interfaces on the same subnet without bonding
you used to be able to years ago but it doesn't work now
note your default route
mike
That's not strictly true. You can use as many interfaces on the same
subnet as you want and traffic to the IP addresses on those interfaces
will come in initially on that interface, but then the local routing
rules will force the traffic out the default route, which would appear
to be eth0. You can change that behavior by setting up iptables rules
that force the traffic over different interfaces depending on the source
/ destination of the traffic.
Or use those 2 lines at the bottom of sysctl.conf and run sysctl -p
net.ipv4.conf.all.arp_ignore=2
net.ipv4.conf.all.arp_announce=1
I haven't found exactly what they mean, but I tested it and it works.

Ugo
