I would bet you have a default route and/or netmask sending the traffic. You will get those arp messages if you run two different interfaces on the same system, on the same subnet (not to be confused with running multiple IP's on an interface.) Arp tries to tie an IP address to a machine address, but if the reverse routing isn't correct you will see these error messages. -Derek -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
