We recently purchased 2 ipcop systems from you. I need to know which color is assigned to what nic port on the back?

If you look at the back of the 1u server cv700a3r10, the Ethernet ports are numbered from left to right as Eth0, Eth1, and Eth2.

By default, Eth0 is GREEN, Eth1 is ORANGE, and Eth2 is RED. Or from left to right: GREEN, ORANGE, RED.

You can change the default setup through the console.
