• Hacky – Restart Network Interface On OpenWRT – Jon's FOSS Blog

  So on OpenWRT for example, a WAN interface can be set get an IP address via DHCP, however, this will launch a separate independent process on Linux to act as the client. On the web interface, there is a button on each network interface which allows you to restart that individual interface (and in addition, it will be smart enough to kill the previous client process and launch a new one as well as re-initialize the firewall and other stuff). I could not find the equivalent command line option to this as a simple ifdown/sleep/ifup would not capture all of these sub-actions as per the extra configurations set on the interface. So I searched and read a helpful hint that can give a similar workaround using the network init startup script.
