Change the state of a device with the command ip link
set device_name command. For example, to deactivate device eth0, enter ip
link seteth0 down. To activate it again, use ip link seteth0 up.
After activating a device, you can configure it. To set the IP address, use ip addr
add ip_address + dev device_name. For example, to set the address of the
interface eth0 to 192.168.12.154/30 with standard broadcast (option brd), enter ip
addr add 192.168.12.154/30 brd + dev eth0.
To have a working connection, you must also configure the default gateway. To set a
gateway for your system, enter ip route get gateway_ip_address. To
translate one IP address to another, use nat: ip route add
nat ip_address via other_ip_address.
