Ubuntu Multiple interfaces on the same subnet

OK, it is working, and for referencing here is how I did it, hopefully someone will find it useful. I found the solution on the following sites: 1- Multiple interfaces on the same subnet 2- Two network interfaces and two IP addresses on the same subnet in Linux And the website that i referenced in the question as well. suppose I have two IP addresses: 7.7.7.4 & 7.7.7.5 on network 7.7.7.0 and they have a gateway 7.7.7.1 I enabled ARP filtering: # sysctl -w net.ipv4.conf.all.arp_filter=1 # echo "net.ipv4.conf.all.arp_filter = 1" >> /etc/sysctl.conf And the I configured /etc/network/interfaces as following: # The loopback network interface auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 7.7.7.4 network 7.7.7.0 netmask 255.255.255.0 broadcast 7.7.7.255 up ip route add 7.7.7.0/24 dev eth0 src 7.7.7.4 table eth0table up ip route add default via 7.7.7.1 dev eth0 table eth0table up ip rule add from 7.7.7.4 table eth0table up ip route add 7.7.7.0/24 dev eth0 src 7.7.7.4 auto eth1 iface eth1 inet static address 7.7.7.5 network 7.7.7.0 netmask 255.255.255.0 broadcast 7.7.7.255 up ip route add 7.7.7.0/24 dev eth1 src 7.7.7.5 table eth1table up ip route add default via 7.7.7.1 dev eth1 table eth1table up ip rule add from 7.7.7.5 table eth1table up ip route add default via 7.7.7.1 dev eth1 up ip route add 7.7.7.0/24 dev eth1 src 7.7.7.5 And I added the following two lines to /etc/iproute2/rt_tables 10 eth0table 20 eth1table
