IGEP Firmware Yocto uses the following Ethernet network configuration (IP addresses)
- eth0 − 192.168.5.1
- eth0:0 − assigned via dhcp.
This Ethernet network configuration is really useful when you work using a Linux operating system like IGEP SDK Virtual Machine. Because you use eth0 device to communicate easily with your board and eth0:0 device to get Internet acces using dhcp protocol.
But some scenarios this network configuration is not useful, for example: if you use a non-Linux operating system, connect to two IP private range interfaces is not simple. This How-to can be useful to
