24 You have aliased three additional IPs to a NIC. You cannot add routes to those
25 aliases, only individual IP addresses.
26
27 You will either have to come up with a routing scheme that routes_eth0 fully
28 satisfies or pony up the cash for three NIC cards.

30 I'd go for option 2 - NICs are dirt cheap.
