The Hm, I don't understand, the received replies are dropped or another host does not reply to our requests? Or we do not reply? arp_ignore does not touch the proxy_arp handling, it filters only incoming requests for local IPs, not replies. You can revert the ARP changes in this order: http://www.ssi.bg/~ja/tmp/arp_ignore-2.6.2-arp-1.diff http://www.ssi.bg/~ja/arp_announce-2.6.2-4.diff 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
