The Advanced Traffic and Routing Howto had everything I needed. It can show you how to setup its IP settings etc.. If you want to integrate into IPTables, the following example shows how simply this can be accomplished.
$ ip address list
1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 brd 127.255.255.255 scope host lo
2: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 100
link/ether 11:11:11:11:11:11 brd ff:ff:ff:ff:ff:ff
inet 192.168.1.2/24 brd 192.168.1.255 scope global eth0
inet 192.168.1.111/32 scope global eth0
3: eth1: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 100
link/ether 11:11:11:11:11:11 brd ff:ff:ff:ff:ff:ff
inet 192.168.2.1/24 brd 192.168.1.255 scope global eth1
You notice that there are 2 addresses on the same interface eth0. I want to forward each IP address to a separate machine on a different subnet in this case, so I would do the following:
iptables -t nat -A PREROUTING -j DNAT --destination 192.168.1.2 --to- destination 192.168.2.2
iptables -t nat -A PREROUTING -j DNAT --destination 192.168.1.111 --to- destination 192.168.2.111
You could have included "-i eth0" if you really wanted to, but unless
you have the same IP address bolted to different interfaces, I don't see
that mattering much.

I hate to ask but do you have and example of using iproute2 for IP address aliases?
Thanks, Mike
