ifconfig eth0:1 <IP address> netmask <netmask> will add an extra IP address to eth0, so it will correctly answer arp requests for that address iptables rules, nothing different than you would have done anyway, except you always refer to the interface as "eth0" no matter which address you're talking about. You can put as many addresses on one interface as you like. Antony.
