if all ethx are on the same switch, you will need: echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore #you can also do it in a per iface basis by default, if you recive an arp request(whohas) on a iface(iface1), asking for an ip that another iface(iface2) has, then the arp request is ansered with the MAC address of the first iface(iface1). If all devices are in the same fisical segment this can lead to a single device answer for all IPs, or to a total caos. This one is very hard to catch and i forgot to mention, now solved :-) -- Luciano _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
