DD-WRT is a Linux-based firmware that turbocharges low-end consumer wireless broadband routers, transforming a $70 toy into a mighty networking powerhouse. DD-WRT brings all the power of the Linux networking stack to these little devices: wired and wireless routing, firewalls, QoS, DHCP server and forwarder, RADIUS server, OpenVPN, VLAN, wake-on-LAN, Wireless Distribution System repeater mode, Kai gaming engine, WPA2 encryption and authentication, and more (see Resources). DD-WRT supplies a nice web GUI administration interface, and powerful, script-able command-line tools. You will learn how to get DD-WRT, to set up secure GUI and command-line administration, and to probe and configure hardware.
