Note that arp_filter is not a perfect solution for clusters because the traffic is mostly out->in, i.e. not originated and the prefsrc is of no help. It can work may be only if your create a permanent entry in these boxes for their gateway because if the reply traffic leads to reolving of the nexthop then you risk to broadcast an ARP probe with the virtual IP as source address and then automatically changes the remote neighbour caches. > Any suggestions? There is a project that deals with same issues: http://www.linuxvirtualserver.org/ Look for Direct Routing mode and for solving the "ARP problem" Regards -- Julian Anastasov <ja@ssi.bg> - : 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
