To the best of my knowledge, there is presently no way to change the arp behavior of Linux such that it uses the interface-based arp mechanizm in a manner compatable with load-balancing and hot-standby techniques involving aliasing the loopback interface. In all the proposed solutions the cache-update by an arp request problem still exists (arp source ip problem). I would love to be proven wrong. Presently I have to either patch the kernel or suffer the throughput penalty of doing dnat to myself, all to do something that Solaris, AIX, HP-UX, *BSD, and even Windows can do natively. --Harley
