implementation of openwrt-based ip pnp gateway
Wireless Networks have been widely used by people with mobile device or laptop nowadays. There are more and more coffee shops, universities, hotels, and other business that provide services of accessing the Internet via wireless LAN. In the small-scale hotspot, like coffee shops and store, using common access gateway to provide service will be a good choice because of low cost and ease to construct. In this paper we will describe how to implement a wireless hotspot access control gateway under the open source firmware platform -- OpenWrt. This gateway will have (1) RADIUS client to communicate with RADIUS server, (2) captive portal mechanism to strengthen access control, (3) dynamic DNS client to be easily connected and managed without the inconvenience of dynamic IP address. And it will also have SSH connectivity and web page GUI. In addition, IP PnP (IP plug and play) will be in the gateway for convenience of use.
