When the device is initially booted, eth0 will default to a static IPv4 address of 10.0.0.101. Eth1 will be set dynamically by your DHCP server on your network.
Each device has two Ethernet ports called "eth0" and "eth1" on the device (eth0 illustrated above, both are available on the Networks page). The Ethernet ports support both IPv4 and IPV6. To change port settings, select Mode from the list. If static is selected, enter the IP address, netmask, and gateway. Then click Submit. Changes apply upon reboot of the IoTServer.
