The above configuration messes up your routing table.

Two things:

1) You should not have IP addresses that are on the same subnet
assigned to different physical interfaces.

2) You should only have 1 gateway address defined.

So, the interfaces file should have:

---
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
 address a.b.c.d
 netmask 255.255.255.0
 gateway a.b.c.254

Hope this helps,
