Since both NIC's are on the same wire, they are both going to see the same ARP request/responses. I assume this error is just indicating that there is already an ARP entry for 192.168.1.100 which indicates that it can be found via fxp0 and it just saw an ARP response indicating that it is also available via xl0 - so which should it use? It's a bit confusing to a machine which has to select the correct NIC to send traffic out. What is the goal of all this? Typically for multipe IP's on the same subnet you would just use an alias - I assume that's not suitable in this case but am not sure why. Aaron
