You need to set up static routes to each of those IP addresses.
Try something like this:
route add 192.168.2.100 netmask 255.255.255.255 dev eth0
route add 192.168.2.101 netmask 255.255.255.255 dev eth1
route add 192.168.2.102 netmask 255.255.255.255 dev eth2
route add 192.168.2.103 netmask 255.255.255.255 dev eth3
If that doesn't work, look at 'man route'
