Ok, I'm being a smartass... :] Mike> By default it is assigning those nics to eth4 and eth5. It's probably due to how the PCI bus get ennumerated. Try using the 'nameif' command to fix which MAC address is bound to which eth* name. You'll probably need to do: udevinfo -a -p /sys/class/net/eth0 and see what shows up. It might be best to do this after setting up all six interfaces (not caring what is where) so you can get their MAC addresses and put them into the table. John
