Is it interchanging the names for interfaces like eth0 for you may be eth1.

so have you used the command arp, to view the arp table on your server ?

how about posting the output of /sbin/ifconfig

Are the two interfaces connected to separate network segments ? or do you have them plugged into the same switch.. ?

Is your switch a managed switch, and does it store an arp table of it's own ?
