Aliasing your network card isn't necessary.  Just assign IP's to it.

ip address add 192.168.0.1/24 dev eth0
ip address add 192.168.1.1/24 dev eth0
ip address add 192.168.2.1/24 dev eth0

I think these might work.

iptables -A FORWARD -d 192.168.0.0/24 -i eth0 -o eth1 -j ACCEPT
iptables -A FORWARD -d 192.168.1.0/24 -i eth0 -o eth2 -j ACCEPT
iptables -A FORWARD -d 192.168.2.0/24 -i eth0 -o eth3 -j ACCEPT
