Is it that Linux is supposed to have this "side effects" of arp linux on purpose ? The "hidden" flag is obsolete, kernel already has arp_ignore and arp_announce vars, see Documentation/networking/ip-sysctl.txt for more information. May be what you need is arp_announce=1/2 and (arp_ignore=1/2 or arp_filter=1 or rp_filter=1).
