Hello,


Do you have a Router on the same subnet? It could be that the router (or any

other L3 device) is proxy-arp'ing for the server IP addresses. Try disabling

proxy-arp ("no ip proxy-arp" under interface configuration of the router and

"sysopt noproxyarp "interface name"" for ASA/PIX) and see if that helps.
