    Default 3rd eth not working after restore of config

    Old box has 2 NICs: eth0/wan and eth1/Lan.

    I am building a new box with a 3rd NIC for DMZ.
    After the initial build I set a static IP on all 3 ports that match the old box's config(see below). I can attach a laptop to each port and ping the ports just fine.

    I then take the config from the old box and restore that to the new box. After a reboot, the DMZ no longer works. I've gone into the networking tab to have it find new NICs, it does that fine. I can configure the IP on DMZ just fine. I drop to the console, do an "ifconfig" but the "eth" does not show up for DMZ. Just eth0 and eth1.
    Reboot again and "ifconfig" again. Still no 3rd NIC even though Untangle's networking tab says it's there and the green light is lit when a cable is plugged in. Pings don't work to and from DMZ.

    Eth0------Wan address
    Eth1------192.168.1.1
    Eth2/DMZ----10.0.0.1

    config -> networking -> interfaces

    Click the refresh button to install the DMZ interface. The backup "uninstalled it".

    That's the first thing I did after restoring the config. Once the config is restored, 2 NICs are listed in the interface menu. I do a refresh and it finds the DMZ. The DMZ then showed up in the interface list with the green light lit when the cable was plugged in. I configured an IP of 10.0.0.1. BUT "ifconfig" on the console tells me that there is not a 3rd eth. I reboot and same thing.
    So what I'm trying to say is Linux is telling me no eth2 and Untangle tells me there is.

    Finally got a chance to work on this again.

    "ifconfig eth2" gets me:

    Link encap: ethernet hwaddr: "it's mac address"
    Broadcast Multicast MTU:1500 metric:1
    RX......
    TX......
    RX Bytes......

    That's it, no IP address.
