If you are not on a shared lan, then it will *ONLY* work if linux is on the other end. No other system will work. And, you don't need an alias on loopback. Merely changing the default route will result in this. Change default route from gw 1.1.1.1 on eth0 to gw 2.2.2.2 on eth1 (making sure that 2.2.2.2 doesn't have an arp entry), and linux will say, on eth1: whohas 2.2.2.2 tell 1.1.1.2 where 1.1.1.2 is the address on eth0. No one will respond to this, so all communication from beyond a directly connected network will now fail. -- Daniel Gryniewicz <dang@fprintf.net> - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
