[Bug 530353] Re: Machine with 2+ interfaces will only respond to pings from same subnet

Some more notes:

root at svc1:~# netstat -rn
Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface

root at svr1:~# cat /etc/network/interfaces | grep -v ^\#

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
	address 192.168.67.20
	netmask 255.255.255.0
	gateway 192.168.67.1

auto eth1
iface eth1 inet static
	address 192.168.62.64
	netmask 255.255.255.0

auto eth2
iface eth2 inet static
	address 192.168.63.100
	netmask 255.255.255.0

- Fixed an IP conflict on the network. When interceptor pings svr1 on the IP on eth2, similar results occur.
- A response isn't generated on any interface. That is to say, if i ping from interceptor to the IP on eth0, a response isn't generated on eth1. Similar for eth2 - a response is not generated on eth1.
